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.

Computer does not detect phone.

Hi there, I reset my Tilt to factory settings yesterday and now when I plug it into my computer it does not detect anything.
The phone does charge, so I know that the connection is there.
I've had this problem before but I can't remember what exactly it is that I did to fix it. I've searched the forum and I can't find anything helpful either.
Anyone know what I need to do to fix this?
Thanks!

You should be able to flash using your micro SD.

Have you tried another cable?

hi, i got this problem tu. i plug in the usb cable, but nothing appeared on my computer.id doesnt say it detected anything (usually it says found new hardware). i tried with several usb cables.still the same. but the phone is charged with all those cables i tried.

Yeah tried it and still got nothing. I am so stuck on what it could be.

I've tried 3 different cables and still have nothing. It worked a couple days ago, but ever since I reformated my phone it stopped working.
I don't understand why my computer doesn't automatically detect it as it did in the past.

reformat it again?
/grasp at straws

My tilt is doing the same thing. 2 days ago I was updating it and when I connected it to the computer nothing happened. Yesterday I tried flashing a new rom, thinking it would wipe it clean and make it connect again, however, it did not work. I am at a loss. Any ideas?

did hard reset and still unable to detect my phone.i'm using G.DK. ROM

i still have the problem
i trized a lot of cables, but from now the computer even don't say that it an unknown plyg is, he simply doesnt detect it. i'm just able to charge my phone, that's it
and in fact i just wanna put the official french rom on it because it's in dutch, i'm bilingual but it's more pleasant to have my phone in my mother language!
tahnks all of you for your help!

Hmmm, this is starting to smell more than fishy with more and more complaints popping up... Just wiped out my laptop thinking it was an update that killed activesync; complete wipe and still no connection; every and any other type of usb cables connect flawlessly from camera, psp, ds, dsi, usb plug in all work no prob; yet kaiser refuses to sync even with new cables before and after activesync updates

Try a different PC if possible. Make sure Active Sync or Mobile Center is installed prior to plugging it in.

--DELETE THIS POST-- I added to it, then accidentally double-posted.

Another one
I'll add to the pile. Exact same problem. ActiveSync doesn't work, but phone does charge. Various cables used, hard reset done. Haven't yet flashed a new ROM, though. I'm using an HTC official 6.1.
Last successful run of ActiveSync was May 8th. I used System Restore on my PC to pre-date May 8th. Still nothing.
Didn't make any major installations to either the PC (XP SP3) or the Tilt on or around that date. It just...stopped working.
All other functions seemed to work normally, except that I got an alert from QuickGPS that it hadn't been updated since that date. I was able to update that successfully.

Same problem on my fathers tytn II... probably HW prob. Will look into it...

Yep, it's definitely a hardware issue with the Kaisers usb port not fully connecting; I pushed the usb bar in a bit with the back end of the stylus and presto! Connected immediately

I'll also confirm success by the use of a little bit of brute force. Back end of stylus, a little manipulation, connect, and the "ba-DING!" sound in XP. Wish I'd done that before a hard reset...

My GT-I9000M Won't Install on my Computer

When I plug my SGS Vibrant (I9000M) into my computer running Win7 Pro 64-bit the icon for drivers being installed pops up in the tray. However, all drivers for the phone fail to be installed. I have installed Kies, but it does not connect the phone, it does continuously try connecting to it though. I also notice the screen of the SGS is flashing. You can breifly see the USB sign on it, but then it just continuously alternates between that and the idle screen in rapid succession. On the idle screen I noticed the top had a bar mentioning mtp application. Any advice in solving this issue would greatly be appreciated. Thanks in advance.

you need try on a winXP computer
many people have reported problem on Vista / 7
you can try to do it again by "Run AS" administrator

I have the same effing problem man. Happened just now and was trying to find a solutions on the forums and your topic just popped up.
The very funny thing is that I am currently trying to connect the phone to my laptop ( WIN7 x64) and it doesn't work while at my office computer running also WIN7 X64 it works flawlessly.
Maybe somebody has an idea about this.
May I mention that I cannot see the phone in My computer and Kies just hangs at the loading forever
I also have the Connect/Homescreen screens dancing and changing back and forth in a rapid succession.

I've had some minor success. I've gotten 2/3 of the drivers installed, but the MTP usb device won't install. I've tried a couple of the ideas floating around when I googled the issue, but still no success with it.

More info in the issue in the FAQ
forum.xda-developers.com/showthread.php?t=723596
Hint: Search in page for "Wuala"
I'm downloading those drivers to try now. I'll get back with results if any.

I've gotten my computer to recognize the phone finally and the MTP USB device driver seems to be installed yet Kies still won't connect to the phone.
The steps I followed were:
1. Unmount Internal SD Card
2. Format Internal SD Card
3. Connect to computer
After those steps it connected fine except for Kies still messing around. The phone no longer does the connect/home dance, instead Kies is in a continuous loop of trying to connect while the phone says it is connected.
I'm thinking of trying the Windows XP Virtual Machine next.

I've tried for hours now with little success for my computer recognizing it, but the little success I had achieved with my previous post undid itself and now that fix no longer works. I've tried older versions of Kies, but the older versions of Kies don't support the SGS and the newer versions don't even recognize the phone. I've done almost everything I can possibly think of and find on google in getting my phone recognized by my comp. I'm so close to returning this phone to go back to my blackberry. If anyone can think of anything that may help, please advise. Thanks again.

Well, the problem has finally been solved. I had to completely reinstall windows to fix it. Hopefully this phone is wort the mad amounts of stress it has caused me so far.

wow, that was pretty insane, have to reinstall entire OS just to get KIES to work?

Pc wont recognize captivate

I bought a Captivate with rogers on 2.1 update 1 today and when I connected it to my PC it wasn't recognized, installed the drivers and it's still stubborn. I booted into Ubuntu 10.10 and still same problem! I can't stand it it's driving me crazy! there's no reason why it should be doing this but I can't make it work!!! Please someone help I am really desperate

There are several reasons this could be happening. A search will come up with all of them. For me, it was the USB port on the computer. It didn't like the remote ports. Once I plugged into one of the ports directly off the MB, works everytime.

You might never get it to work
I've been reading these posts and trying suggestions since I got my Captivate back in August. I still have not been successful in getting any kind of reliable connection between a computer and my phone. This is my second phone and I have tried 5 different computers. One of the computers was tried with Win XP, Windows Vista and Windows 7. Nothing seems to get me a reliable connection. I hope you have better luck. I get a wild hair every now and then and spend a few more pointless hours trying to make it work but to this point nothing is working. I've tried Kies, Kies mini, old drivers, new drivers, 32 bit drivers, 64 bit drivers, etc. NOTHING HAS WORKED. I've managed to be able to mount my drives and copy files occasionally but no kind of sync where anything is automated. Also I have found nothing that can get me any sort of contact or calendar sync with Outlook. My work prevents me from putting everything into Google mail and syncing that way so I'm just out of luck with a phone that ATT told me I could sync with Outlook. Maybe Froyo will fix this or else I have to wait my year until I'm eligible for an upgrade to get a phone that actually works properly (ie, non Samsung), although I have to wait for OTA Froyo since Kies won't be of any help in upgrading anything!

This is the best drivers i found to make it work on my Vista box.
http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x86.shtml

The USB drivers from Samsung's website seem to be pretty bogus.
If the ones from the link above don't work you can go here - and download the USB drivers for your OS there. I have tested both and they work great on my computers.
And... if your running Vista - IMO That is Issue #1

... That OS was never a issue for me.. i found the user using it is often the #1 issue

LOL I refused to run it. For some reason my systems refused to run it and I always ended up going back to XP.
Now with Windows 7 - I think Microshaft got it right (as close as they can) and its what Vista should have been to begin with

Usb debug is only for adb to work. You can still mount/detect the phone without it. Windows should detect it as a usb mass storage .

Thanks for the response. I've had debugging turned on and off. Neither seemed to make much difference. I did find one interesting thing the other day though. I uninstalled all Samsung software and drivers. Before I tried any kind of reload I used a registry cleaner to clear out any remnants. It seemed to act a lot differently when I reloaded things and I actually managed to sync my calendar and Contact List although not with Kies or any Samsung software. I used a program called MyPhoneExplorer. It takes a while to figure out but seems to work well if you have a decent phone-computer connection. It only worked once though and the next time I plugged back in there is no connection. There was a time when I was hopeful that Froyo would fix this but now I'm doubtful that the Captivate will ever get Froyo, at least from Samsung or AT&T.

I totally do not understand this phone when connecting to my PC. I am sooo sick of this thing not being recognized and trying to connect with Kies!!! I would run better odds playing Russian Roulette at being the big winner!! What other options do we have to get our phone to connect so we can load an unload our media. I dont have the space to load my whole library and wouldnt want to wait the years it would take to load it :|

I can't connect my Captivate to my Windows PC or Ubuntu through the USB cable that came with the device. I think it's the cable that's short circuited resulting in no connection so I will get a cable asap. My temp solution was an 8GB microSD but even now i tried rooting with the update.zip file and I had no luck I don't really care if my phone connects to the computer as long i have a microSD card reader and rom manager too bad for my 16GB memory but I can't even root! I hope they fix the update.zip file. This phone has killer hardware. It's such a shame how it's being brought down...

Have you tried connecting to a USB port right off the MB? I know my remote USB ports would charge the phone but were flaky when trying to connect to my computer. Moving to the MB USB port fixed all my problems. Connects everytime now.

Well I only have a laptop and I tried all the ports...

If you truly think the USB cable is bad - then I would suggest going back to your retailer your purchased it from and get another one.
Also - if you want to ROOT your phone - you should still be able to. I would download the CLShortFuse's 1 Click Root application. Then you can copy the update.zip from inside that application's folder and copy it to your internal SDCard like you have been doing then flash as normal.
It will not include SU or Busybox I think though - or enable sideloading of applications. You will still need to d/l ROM Manager and get busybox that way.
I wouldn't recommend flashing ROMS to your phone until you can get it to recognize though. Please tell me you haven't installed kies? And I would go to the Q&A sticky - it has the 1-click root app as well as the USB drivers I recommend installing to have your phone recognized.

I install the usb drivers for xp and never had an issue with 2 home laptops and 2 work laptops. Wife's windows 7 machine i did not even have to install drivers and it recognized it without issue. Make sure you are using the cable that came with the phone as i have had issues with other micro usb cords that did not come with the phone.

I tried the USB drivers you posted on another PC and USB cable and it worked like a charm!
Thanks alot!

If all you want to do is copy media you can get by without Kies I believe. All you should need is a proper driver setup for your computer. Once drivers are loaded and recognizing the phone all that should be left is to mount the drives on the phone. Just be sure to have the phone in "Mass Storage" mode instead of "Kies" mode. I can't get Kies to work for me but from what I understand the only real benefit of that is for doing upgrades, I might be wrong though since it doesn't work at all for me.

[Q] Kies says no Note computer says its there and working

I may be stupid but what is the problem with this Kies program. I was sent a Note by my daughter to replace my HTC but even after upgrading 90% of the time it says it cannot connect to phone but all the computers recognise the phone and I can use drag and drop quite easily. However, when trying to download facebook app it ended up in Kies at first it said there was no phone and then when it discovered there was a phone it said there was no memory or SD card is it just a crap piece of software. Kies has also failed four times to upgrade the firmware, now I'm getting seriously cheesed off
Just solved the updating problem both the phone and Kies were trying to carry out the same update at the same time and in the background

first of all Mac's having problem with Kies, second did you upgraded Kies to latest version, third did you start Kies as administrator, fourth did you reinstalled Kies, fifth did you disabled USB debugging on the note, sixth did you tried searching with Google or search option on xda? if you answered yes to all i don't know any other issue with Kies not finding a device.
