USB Device Not Recognized

I've been using my AT&T Tilt for nearly a month without any problems, but yesterday for reasons I cannot determine, my phone suddenly stopped being recognized by any version of Windows XP or Windows Vista. I tired Windows XP SP2 in a virtual machine on my Mac, I tried it on my wife's Windows Vista machine, and I tried it on my children's Windows Vista machine and I received the same error each and every time.
No matter what machine I plugged it into, I would immediately get a "USB Device Not Recognized" error and neither ActiveSync on Windows XP nor WMDC on Windows Vista would initiate a sync.
I've hard reset my phone multiple times, I've uninstalled and reinstalled both ActiveSync and WMDC, I've even flashed to a different OS on my phone (using my MicroSD card) and nothing has worked.
I'm beginning to wonder if maybe the USB connection on the phone may have failed. I've been contemplating sending it back to AT&T since I had a malfunctioning pixel in the middle of the screen, but with the recent problems I'm starting to lean more towards returning it and less towards living with the pixel issue.
Anyone have any ideas on what might be causing the USB problem?

Just a quick update, when I arrived at work today, I attempted to sync with my work computer (Windows Vista Business) and I had no trouble at all. I'm going to take home the cable that I have here (which came with the BlackBerry I use for work) and see if that makes any difference with my home computers.

wow
I can confirm this as well. I have the Tilt and I used a blackberry cable from my job and it synced up flawlessly. before i was getting that usb not recognized as well.

I'm having the exact same problem now.. it worked fine for 4 months and now.. it just says usb not recognized. Please post the results if your blackberry cable. thanks

I just tried a brand new usb cable and it still didn't work for me

I have the same problem but i've got a solution for this and it's very simple.
For someother reason ActiveSync will boot on the background of your device even when you close it, it will boot up within 10 min or less.
This is the thing you need to do:
Before you plugin your usb cable to sync......
Run taskmanager and close activesync. When you are sure that this application is not running then plugin your USB cable.
It worked for me!

I've tried that, didn't work

I had this exact same problem happen to me at the end of November - I was using WMDC 6.1 for months then all of a sudden I could not connect (same error message you described). I went back and looked through the MS Windows updates and identified a NVIDEA driver update had caused my problem. Used system restore to roll it back and then everything worked fine.

ya..i bought my girlfriend the HTC Touchdual and has the same problem as well. She can't seem to sync with her Win XP and is only her 2nd time trying to sync and it failed already. In between, I don't think there was any internet connection to update anything.
Please help!
(Sorry to borrow this thread to solve the same problem but on another device btw, I own a Kaiser myself but currently didn't face any problem yet..touch wood!!)

Dwimmerlaik, did you have any luck fixing the problem?

Solved my USB Connection issue in Vista
After trying everything I could find on the net to solve my inability for Vista to stay connected with my HTC Kaiser (ATT TILT), I found the problem exists with the MicroSD card. No matter what, Vista would connect then disconnect my phone after a few seconds. After weeks of searching I finally just decided to take out my 2Gb MicroSD card.....and now Vista maintain connections and I am finally able to sync via WMDC.
Spread the Word!!!! Take out the MicroSD.

too bad I'm not using Vista..

Anyone else have this problem and solved it?

-Try to use the USBs at the back of your PC(not on the front of the case).
-Try to buy another cable(That SHOULD BE an USB2.0 HighSpeed certified shielded cable. That costs something about $6 ).

Didn't work for me either
I've tried doing that multiple times..

Go to phone, menu, options, time zones tab, uncheck the Auto change time zone & clock.
This is a known bug in the firmware that causes A/S to automatically start & then sometimes it tries to start a second sessions of A/S when you plug in to your PC. Give it a try, have you ever noticed that A/S is running in task manager even though you're not connected or just reset? Just one thought.

My computer dont detect my HTC TyTn II

After a hard reset on the TyTn my computer is no longer detecting it when I connect the phone to USB cable. The computer makes a sound when I connect it, but Windows Mobile Device Centrer say that TyTn II is not connected, and it does not show up in My Computer eather.
I've tryed to delete the partnership and reconnect the phone, but nothing happens.
Can anyone help me please! Now I cant install any of my programs og transfer files between the computer and the pocket pc/phone.

Try this:
tap Start > Settings > Connections.
tap USB to computer.
Uncheck the Enable advanced network functionality box

Try this:
tap Start > Settings > Connections.
tap USB to computer.

I uninstalled Windows Mobile Device Centrer and then tryed the tip you described here. At first it looked ok, my computer detected the device and installed the drivers and reinstalled Windows Mobile Device Centrer.
But my device is still not showing up in Windows Mobile Device Centrer or My Computer

Check your personal firewall settings and open the ports MS asks you to at the Windows Mobile home/support page...

Go into task manager & see if Activesync is running. I have the same problem with my tilt & if I kill activesync then reattach it takes a moment the first time, but then it works.

Make sure you are running the latest version of WMDC. I absolutely could not get WMDC to work with my HTC Wizard for months. After MS came out with an updated version of WMDC (around June, I think) it started working fine.
If you absolutely can't get it to work, consider using emoze for over the air syncing of cal, contacts, mail, etc. (or an on-line exchange account.) I had to do that for a few months until I got it to work. Emoze has the advantage of being free. Unfortunately, neither will allow file syncronization, tho.

There is no activesync running.
And everything was working just fine before my device went "mental" and I had to hard reset. So before the hard reset I could use WMDC on this computer, transfer files and run active sync. But now I cant.
I also got an online exchange account so I can sync calender and contacts. But I want to be albe to transfer files to my computer and install new software.
My WMDC version is: 6.1.6965

Some more info about the computer may help. For instance, I take it from your usage fo Windows Mobile Device Center that you are running Vista. In any case, since the problem is with the computer and not the Kaiser, I would see if the manufacturer would provide some support.

Yes, im running Vista and I buildt the PC my self.
But Im not sure its realy the PC that is the problem, because I made the changes (Hard Reset) to the device and thats what caused the problem.
Anyway, I was hoping for some way to debug/troubleshoot this problem.

I am having the same problem. I sync to any one of 8 computers at work and one at home. Work runs XP PRO and Home VISTA Ultimate x64 all worked fine untill this week. I have not made any changes since the last sync, the computers know it's hooked up due to activesync opening and trying to connect when I plug in via USB. But it never connects. I want to flash to Dutty's newest ROM but can't connect. I sync all contacts and e-mail wirelessly but need the computer to flash (I do not have a sd card yet) Any idead would be great! I have tried the ideas listed above but no joy. I have not hard reset the device as of yet ( I need some things off of it first)
Steve

BUMP
I really need help with this!!! I'm pulling my hair out!

Did any of you that had this problem find a solution? I have the exact same issue except a hard reset will fix it for a while, and then the problem will reoccur a few months later. No software has been added during the time frame. Very annoying.

i've got just the same problem! plaese help us!

New Xperia will not connect with Vista

Hi,
I am getting a bit frustrated over this.
When I connect my X1 to my Vista x86 nothing happens (well the USB task tray icon show for about a second and vanishes again).
When I disable the "advanced option" in the USB/PC connection settings in the X1 I at least get a USB connection with something identified as "PocketPC USB Sync".
Any idea why this is happening and how I can get a real connection with the win mobile device center?
Thanks for helping me out!
Cheers,
Tillman

maybe give this a try:
http://modernnomads.info/wiki/index.php?page=Windows+Mobile+Device+Center+Troubleshooting
I've once had the issues of not able to connect my Windows Mobile device with vista too, and it can get very annoying.. good luck with it.

You might want to try and disable the firewall and then connect the device. I had this problem with Sygate Personal Firewall (sygate was bought by symantec and personal firewall is now terminated and no longer available)

Thanks for the quick response guys!
I already tried disabling the firewall (nod32) but that did not help.
Also checked all services - everything is peachy in that department.
But still - no connection.
When I switch back to "legacy mode" (disabling the advanced option in usb/pc settings on the device) then the device will tell me that I need to install active sync 4.5 or higher and wmdc still does not connect.
This is really strange...and annoying and the same time.
Any more ideas or any way for me to debug what's going on?
Thanks for you help!

Have you intalled "Windows Mobile Device Center 6.1" on your Vista-PC?

The MobileDeviceCenter should be standard without the need to install...
At my Vista Home the X1 had no problems to connect.
Open the Mobile Device Center and delete all old connections of other PPC. Then start your PC again, Softreset your X1 and try again. This should help. I had the problems too, when first connecting, because he didn't liked my G900-connection which was first
After this I too could install my G900 again and no problems since yet (2 weeks).

Well sometimes the Mobile Device center could stuff up or not work due to some issues such as installation of Mobile Device Center 6.1 went wrong. I have experienced that I think I didn't follow the procedures correctly and things just wouldn't work. Eventually I had to do some uninstall and reinstall many times to finally get it working.

When I first plugged mine it it installed some drivers but didn't show up in the Mobile Device Center; unplugging and replugging in caused it to work...did you change settings in between plugging in for the second time?

What I have tried so far (and nothing worked):
Uninstall / reinstall WMDC
Uninstall / reinstall Win Mobile Remote Adapter (yes, this does show up once I am connected with "advanced" USB mode)
Uninstall / reinstall "PocketPC USB Sync" (shows when X1 is set to legacy USB mode)
When in "advanced" mode I can also see a new LAN connection showing up in network overview.
The same X1 on a different Vista 32bit right next to this one will connect just fine. So it's definitely about a driver or config thing with this Vista.
This is driving me...well you know what.

btw, you did try restarting your comp when performing some of those steps, and you did try different USB ports right?

I know that you had to ask.
Yes I did. I have rebooted the system several times in between all those reinstallation tasks.
By the way. When I am in USB legacy mode and reconnect the USB cable then the X1 will show a messagebox telling me that it's connecting with the host and that the user credentials / user account (having to translate here) are correct.
But still NO connection visible in WMDC.

I had the same problem with my X1. I assumed that because my HTC Diamond worked the X1 would as well.
I finally installed WMDC from the SE install cd, and bingo!! al good. Hope it works for you...

Wow!
Even though it does not work (yet) it's showing some new signs.
Installing WMDC from SE disc fails at 99% progress and then rolls back.
There's gotta be some installation error log this, right?
Thanks for coming up with that suggestion. Really, I should try installing from vendor CDs more often instead of hunting down the latest version on the net.

maybe give event viewer a try and check under Windows Logs (not sure if it will be application or system tho)
just in case you aren't sure, in vista either type in "Event Viewer" in the start menu search bar, or type in "eventvwr"
Don't you just like vista?

That helped (to install SE's WMDC). The issue was that my HTC Universal was still connected to one USB port (for testing purposes since that device is not recognized either).
As soon as I unplugged the HTC I was able to complete the WMDC installation.
Unfortunately though it still won't connect to my X1.
Any more ideas?

what is your settings in Windows Mobile Device Center connection Settings?
Well here is my settings that is working with my x1:
Allow USB connections checked
Allow connections to "DMA"
This computer is connected to "Automatic" (this shouldn't matter)
Allow automatic device authentication checked
Allow data connection on device when connected to PC (this shouldn't matter either)
also, while this link was in the first link that I have posted for trouble shooting, just want to make sure you actually tried The offical Windows Mobile Device Center troubleshooting guide?
http://www.microsoft.com/windowsmobile/en-us/help/synchronize/device-center-troubleshooting.mspx
namely these steps:
Quote"
If Windows Live OneCare is installed on your machine, it may be blocking the device connectivity. Please click here for the steps to configure Windows Live OneCare to allow the device to connect.
My device wasn’t connected during this installation.
While it is not a strict requirement that you have a device connected during the installation process of Windows Mobile Device Center, we highly recommend that you do.
"

I didn't have the DMA set (changed that now). Everything else already was like you described and it does not work.
This really freaks me out. I always hated my iTunes/iPhone connectivity but that honestly works much smoother. Of course I do understand that this behavior is non standard as I have experienced myself that the phone works with my other Vista machine but that does not really help me here.

Any update on this? I am having the same problem.

I'm having the _exact_ same problem too, but in Vista x64. I don't know why WMDC can be such a c**t sometimes, as I have never been able to 'sync' with my Media Center PC.
My only saving grace is that my laptop has Bluetooth, and syncing works great on it. I have never had success connecting the USB cable (with many options changed around of course) to either of these computers. Only Bluetooth syncing works for me...
Hopefully we can find the answer!

What USB cable are you using??? the one that came with Xperia??? Cos the one that came with my Xperia never worked out of the box, it could only charge...
I also got another extra cord which came in another box, that worked fine for both syncing and transferring data until today, now it says USB device not recognized, maybe I was trying the flash X1 with new ROM through SEUS, did the whole lower volume key and power button to get the 3 strips.
Now I am using the USB cable that came with my external HDD, that's currently working, hopefully it won't fail me.
so any ideas??? I don't want to keep changing cables...

Kaiser and x86 Windows 7.... It works finally!

Just tried to set it up again after a few months of it not working and an updated driver is now on Windows Update for you to use. Give it a shot!
Just wanted to post up for those who were feeling stuck like me.

Just installed Windows 7 Today and my kaiser doesnt sync. I tried teir new drivers and still nothing.

Yeah and Windows Mobile Device Center 6.1 which comes with windows 7 doens't work with Windows Mobile 6.5 which Im running on My Kaiser. Im so pissed I upgraded to windows 7 ... i wish i was still on xp

Worked fine for me.

works fine in x64...atleast for me!

I can confirm 6.5 works with 7 x64 I can also confirm that I cant get this to connect to my 7 x32 netbook, I can make it do everything but ActiveSync which includes Internet sharring USB and Bluetooth.

I'm running x32 ... What do you mean it will do everything "BUT" activesync. Thats kinda what i need it to do.

Ok ... i figured it out finally. WMDC wouldnt even run or Install, i should say, even though there was a setting portion in Control panel for it.
I found a article about how It wont run without running windows media player first. ( fresh Install and never ran it yet) So I went to run it only to find out It didnt exist.
I'm running Windows 7 Ultimate N which didnt have any Media Software included. ( Didnt know that) So, I downloaded the whole media pack and installed. then I ran media player once and Voila! All the phone drivers installed properly, WMDC Installed properly, Phone connected and sync'd.
Whew!! I'm glad thats over. I almost went back to XP Pro.

I'm running two PCs with windows 7, one desktop with Windows 7 Professional (home) and a laptop with Windows 7 Ultimate (office). Currently I'm trying to sync to my laptop since that is what I sync to most.
After reading your post, this is what I tried:
1. Windows updates, it did install some windows mobile thingy which failed. I rebooted the machine, re-ran the update and it installed fine
2. Tried installing Windows Mobile Device Centre 6.1 (64-bit version) again, but it failed. Same message of Unidentified device and status of failed
3. I also tried your solution of keeping windows media player running before attempting to install WMDC, but no joy
Can someone please let me know how I go about this? This is frustrating, if I can't synch my pda I might as well throw it out (since I can't chuck out my laptop or job )
BTW, I'm running Windows Mobile 6.1, should I be upgrading this to 6.5 as I have read out here? I've searched on this forum but can't seem to find a download link for 6.5 (or perhaps as ASCIIker pointed out I'm going blind )

Mobile Device Center
I read this post and then was successful at installing device center. It was a weird install though. I am running 6.5 on the Tilt and Windows 7 64 bit on my laptop. I plugged the Tilt into the computer, started Media Player and configured it, and then launched the installer. It ran forever with the status bar saying 7 seconds to go. All the while, the diriver software was still trying to install. I finally got an error message from the driver software saying that it did not install properly. I opened up the troubleshooting box for the driver install and looked around a bit. Eventually, another message popped up in the driver install box saying it was trying again. Eventually, I another failure appeared. At that point, Device centered finished installing, the Tilt connected and all was well.
Total elasped time 20 minutes or so. Enough time to read a couple of pages on a new (to me) Andre Norton book and eat most of a popcorn popper full of popcorn.
Whew.

Nice to know it got solved.
It works fine for me:

This is the part I don't get, what exactly do I configure in Windows Media player? I plug in my phone, however, it doesn't seem to do anything, if I start windows media player and go to the sync tab, it is greyed out with the message 'Connect a device' Do you also uncheck the 'Enable faster data synchronization'? If I uncheck this, it does seem to try and install drivers for some 'Generic Serial' device but eventually comes back with 'Failed'

Why should it be so hard, I thought Windows 7 was supposed to make life easier, they obviously haven't heard of the phrase, 'if it ain't broke, don't fix it'

any solution?
Please. Iam really sick of it.
I can move files to kaiser, I can install via PC, I can acces my PDA via My Mobiler - but I can't sync! It just cycling the arrows and "syncing".
Please help, it really sux without contacts and calendar and you know - outlook.

The media center was just the initial configuration that runs when you first start it up.

Kaiser TPC 11 mega and WMDC
The only way I've gotten Windows 7 WMDC to recognize my Tilt using TPC 11 Mega ROM is to connect using PAN over Bluetooth. I think the problem is that it doesn't report to Windows 7 that it's a Tilt or that Windows somehow knows that it's not supposed be running WM 6.5. Kinda sucks, but at least it works. To reflash I had to use the SD card since USB won't work.
I tried everything under the sun to get it working over USB. Finally had a friend with a Sprint Touch connect his using USB and it came right up, showed a little picture of his phone and worked fine. So it's definitely something in the way my Kaiser/Tilt is reporting the device to Windows. My phone is recognized by W7 and displays as a PDA, not a phone.

I'm on build 7100 and my Kaiser has been syncing flawlessly for months. My new Droid, on the other hand...No happiness yet. I've already made the call to swap the Droid for a TP2 strait across.

Been running 7 for a while now, both 32 bit and 64 bit dual boot. I've never had any issues with it not syncing, otherwise I would never be able to flash any ROMs on my phone. I even reformatted and reinstalled both after getting a legit copy from the MS Tour and it still works fine.

[Q] Update error 801812C

Hi
My beloved HTC HD7 on O2 (Unlocked now) advises me that their is an update.
I imagine this is the pre-update to the No-Do update
However everytime i try to install i get to stage 6 and then the error 801812C is reported.
I have searched this and found the same answer in every article regarding-
"During Step 6 (Rebooting your phone), your Windows OS detects your phone as a new device and starts searching for driver updates online. This can be seen when you click on the little indicator with a spinning green circle in the bottom-right corner of your desktop called the notification area (you might need to click on Show Hidden Icons if it's hidden)."
"You have to *immediately* click on "Skip Obtaining Device Software Online" or Zune will time-out and show error 801812C1"
However i see no option come up on XP to allow me to stop such device updates. And i definatly have no hidden icons!
Someone please help with a better solution...
Jayne (Yes i am a girl so be nice, so sartactic answers please, I am Tech savvy but this one eludes me)

From what you post, it sounds as if maybe you have to right-click the notification icon in the system tray for that option.

From what i understand from the OP's first post, she doesn't have the icon so can't right-click it.
I know it's not really a solution, but have you tried updating on a Windows 7 machine? I've always thought that windows 7 is more compatible with WP7. I know this isn't excplicitly mentioned anywhere, but why else would the Dev Tools only be available in Win7? strange....

Windows 7
Many thanks
Yes indeed no notification is showing and I have set the taskbar not to hide inactive icons so nothing can be lurking!
I will see if i can find someone with Windows 7 as i'm a XP user through and through lol
Many thanks for the ideas so far but if anyone has another brain wave please contribute, I don't want to miss out on the proper upgrade when it arrives..this week fingers crossed eh!

same error here
Hi Jayneh,
I too have an HD7 on o2 (Sim unlocked, but stock otherwise).
I am also an XP sp3 user, and I'm getting the same error as you, 801812c1.
The update fails at step six. The phone will reboot and then show a picture on the screen suggesting I connect my phone to the pc, despite the fact it is connected already. I've tried three times with no joy so far.
I've done some searching and as you say, the current theory is that after rebooting the phone, the pc doesn't recognise it as WP7, but Wm, and proceeds to hunt for the right drivers. This will of course fail, and the update times out.
Several users on different model of phone have reported the error and Microsoft are advising you hold off updating until the issue is investigated.
A number of users are saying they are using Windows 7, so it can't be an Xp specific problem.
Several fixes have been reported by some users which include unplugging and re connecting the phone quickly, or stopping the pc hunting for non existing drivers by clicking the update icon in the notification area. This does not seem to work for everyone.
I have tried unplugging which didn't work for me. I looked for the update icon but can't see one, but in anycase, my machine runs incredibly slowly during the whole process so doing anything at all is frustrating.
One thing I haven't seen anyone reporting is whether they use the same machine to sync a WM6.1/6.5 device or not. I do, but I'm just grasping at straws here.
I'm also slightly worried as I only have a little over 10GB left on the laptop.
Here's hoping NoDo isn't a NoGo for us.

Many thanks Garrickus, as long as i'm not alone with this and it is being looked at, hopefully if all else fails the fab developers on here will soon have us an update rom we can port straight to our HD7's. Fingers crossed and hope the sucking up to the developers speeds this along

One solution to the 801812C1 error code
jayneh & Garrickus,
Do you have windows automatic updates turned off?
I had automatic updates turned off (XP Home 2002) and I had the same problem when I first tried updating.
After reading something elsewhere, I turned automatic updates back on and tried updating again 24 hours later. It worked, with the update running smoothly through all 9 steps without a hitch.
I don't know if you have to wait after turning automatic updates on, I just thought it would be prudent.
I'm also using an HTC HD7 on the o2 network. I hope this information helps you like it helped me.
Ian.

Automatic updates
Hi Ian,
Thanks for your feedback regarding automatic updates.
Unfortunately, I have automatic updates turned on, and PC and Zune are fully up to date, so that's not an option for me.
Interestingly, Zune had a minor update after a couple of failed phone updates and now when the little bubble pops up it describes my device as 'Zune' not 'Windows Mobile', but still getting same error code and updates fails exactly the same.
I see their is no specific response to this error code from Microsoft as yet
Are you still experiencing problems Jayneh ?
Garrickus.

Update
I was still having problems and my PC was/is up to date and automatic updates is on.
I say was because i now have the NoDo update having followed the brilliant update method by Petbede for updating without a gold card.
It went smoothly and here i am with a speedy phone and cut and paste. My god bejewelled loads so much quicker

frustration
Im using Vista, have the same problem as Garrickus. HD7 on Vodafone network. After reboot the device pops up as Zune device and computer tries to look for Zune drivers, after some time it gives up. I have tried all ways of updating drivers, nothin works.

Hi everyone,
I experienced that problem today downgrading my HD7 with Zune installed on XP SP3, three times it didn't work...then i closed all running app like firefox & other utilities...and the downgrade process worked at least...
My advice : just be patient!

Update WP7 driver on PC before running the WP7 upgrade
The error '801812C1' appears when the phone is wrongly identified as a 'Zune' device (MS MP3 reader !) after the phone restarts at step 6 of the WP7 March 2011 upgrade.
In order to set the correct WP7 device on the PC:
1. Shut down the phone (press & hold the power button)
2. Restart the phone and press & hold the camera button
3. A black screen appears on the phone showing a device connected to a PC
4. Connect the phone to PC on USB port
5. Open Device Manager on PC and check the entry for Portable Device: 'Schubert' (= HD7) or other name (depends on your phone).
6. Shut down the phone (press & hold the power button) and restart it.
7. Connect the phone to PC and run the WP7 upgrade from Zune.
The error '801812C' no longer occurs at step 6.
