USB device not recognized all of a sudden - Tilt, TyTN II, MDA Vario III General

Im hoping that someone can help me with this please.
For no apparent reason this came up on connecting to my office pc yesterday, I tried at home today with the same error on two separate machine.
Have searched the forums with a few dead ends where people have resolved but no reasons given.
As others have done have backed up settings etc and reset my device in the hope that maybe mobile shell 3.5 might have been at fault but sadly not.
Ive taken a look at the usb port itself and the second pin from the left appears to be very flat in comparrison to its neibours, could someone confirm this please before I start prodding about.
thanks

Do a search in this forum for USB connector -- you will find lots of advice.
Also, if it happens on multiple machines, and you're using the same cable, try a different cable -- these can go bad too.

TyTN II USB Drivers?

My TyTN II isn't being detected by on my PC.. I've tried uninstalling everything and reinstalling everything, but no luck.
Where can I find USB drivers for the TyTN II? I don't recall installing it when I first got my phone, but someone suggested it, but I can't find it anywhere.

Are you connected via a non-powered USB hub as this can sometimes cause a problem.
Have you tried a different USB cable? I spent a day trying to resolve the same problem on my Universal a couple of years back, only to find the cable was at fault.
EDIT: Did find one other thing a few months back. I installed one of those business card scanners to my laptop and found that whenever it was plugged in, my phone was no longer recognised.. Seems the scanner was pulling all the available USB power for itself.
I've tried 3 different cables on 3 different computers
I'm not using a USB hub..
Did you try changing the advanced settings for the USB-PC connection? I have had that, when I uncheck that box all is good.
Start->settings->connections->USB to PC-> uncheck Enable advanced network functionality

I know this may sound stupid but you are using Activesync aren't you?
I just ask this as you have not mentioned it. A WM device will not be just recognised as a USB device like a printer or other peripheral.

If you have tried it with three different PC's then it does sound as if the port on the phone may be at fault.
One last question, did it work before at all?
Anyone else with any ideas

Yes I've been using it for 4 months and had no problems. The port on my phone works, I've been using my headset and it charges when I plug it into my PC.

Take a magnifier and look at the port under a good light. See if everything looks OK.
Also check another thread close to this one regarding battery drain whilst connected. Could be that you have a damaged port and it shows different symptoms to theirs.
Someone on that thread says it costs $80 for a repair but hang about a few days, someone may come up with a better answer for you.
Hope you get it sorted.

Port looks fine.. but my batteries draining.. This started 2 weeks ago.. and I've been charging fine.
No I do not remember if I installed drivers or not ... sorry. Try using bluetooth connection to sync. if all fails. I have had that with my old P910
I really think there is something going on here - I am starting to see loads of threads relating to this.
I am also having problems syncing suddenly. Started about 2 weeks ago. I have dual boot on my laptop - vista/XP and my Kaiser wont sync with either anymore.
It seemed to be charging fine up until yesterday when I again suddenly couldnt charge it from anything other than the official charger. Before that I had charged it on pretty much anything - my proporta power supply, sync cable attached to a USB plug, blackberry charger.
If its hardware then there is obviously a weakness with the USB connection as so many people seem to be experiencing similar things.
Maybe time to contact HTC although after their response to the video drivers, wouldnt hold up much hope.

Yep done the standard stuff with people for the last 8 months. Whereas it may or may not be attributable with this problem... I am trying to collate data.
Trouble is, a trend is starting to occur with damaged (PHYSICALLY) mini-USB ports that are not done by the old 'Sticking the stylus in the port'.
There is a trend of failure when using a STANDARD mini-usb connector in this port. It is a non-standard connection so if failure occurs it needs to be rectified.
Hey, I aint doin a lawsuit, I am just working on a free refurb and advising HTC to modify AS IT SHOULD BE!!!
Just for grins, try to connect via IR or Bluetooth ...

Hi
First of all try to reinstall Microsoft ActiveSync, than in the ActiveSync options, in your device, be sure that in "Connections..." setting "Synchronize all PC by this connection" is checked and below "USB" showed!
Otherwise, if your device, when connected to the PC, also doesn't charge (if you have this option enebled on your PDA!) there is some problem on your PC settings concerning the USB! Try to connect to someother PC to test it!
Ciao
thx...

hello there, first n foremost thanks for your input!
Before trying out your possible solution i tried to connect and for some reason i was able to connect via the device today...??!!
i really dont know why, but will try your soln if this situation reocurrs.
NB: this happenned to me twice in the last 3-4 months, n i never figured out the cause ??
any other advice or ideas gratefully accepted.;
its probably the same as me and loads of other people - the pins have bent on your usb connector - probably caused by using non standard chargers and usb leads. Its been widely reported. The non-standard leads have too much space around them when plugged in and wiggle causing the connector on the tytn II to bend. Try using the lead which came in the box and see if it helps. and try using the charger that came with it too.
Can bent pins be fixed?
Hello -- I'm one of those people with a non-recognition problem. Is it possible to fix the bent pins? My problem seems to have begun around the time I lost my original USB cable. Now, all the cables I have -- ones that have been specifically sold to work with my HTC Tilt -- have the symmetrical, sort-of-trapezoidal mini-usb connection, rather than the rectangle-with-one-corner-cut-off shape of the original cable. I should say these cables do charge my device, but none of my computers recognizes it as a USB device.
Help?
Thank you,
J. Georgia
bent pins continued
I should add that the charging cable that originally came with my phone has the same connector shape, so I'm not sure what's going on.
USB Device not recognised
This is known to happen at times win Windows, and not just for the TYTN2 but a myriad of devices.
The fastest fix for this:
Reboot ur PC/ Laptop.
If this Doesn't help - Then add in a reboot for the TYTN 2 also.
The problem will go away for some time.
I know its annoying, but this is way faster than troubleshooting for contacting MicroShaft Support.

Unfortunately this is no soution for me. I seem to have this problem as well, since about two weeks.
I use two notebooks (Dell & Acer) and both do not show any activity when connecting my Kaiser to the original USB cable. The device is not even switched on when I connect it, nor does this happen when I connect it to the (original) cable in my car, which did work before.
Charging works fine, both in the car and when connected to both notebooks, but no Sync at all.
I have tried another USB-cable with the same result, so I suspect some hardware-problem causing me to be unable to copy files between my notebook and my phone and worse, rendering me unable to flash a new ROM onto it.
Who knows what to do next?
I am mystified, too. USB Charging and audio connections work. I have rebooted my computer and done a soft reset on my phone several times, to no effect. I uninstalled and reinstalled Windows Mobile Device Center. Still nothing at all via USB. Once, yesterday, I somehow got a Bluetooth connection long enough to sync, but haven't been able to since then. Even then, Windows Media and AudibleManager couldn't see the phone. The really weird thing is, I can see the phone connection in my Bluetooth manager, but even with all the proper boxes checked, I can't sync. When I try from my device, I get an empty progress box which disappears after a fraction of a second. When I try from my computer, it says the device is not connected, but doesn't give me any option to connect.
Would a hard reset help?
If so, would returning an unlocked AT&T Tilt to factory defaults lock it back up? And what do I do if it does?
Please help!

I have had similar problems with my touch pro in the past, even bluetooth internet sharing eventually gave up the ghost.
I tried a myriad of leads and then eventually reinstalled active sync- which did the trick.

I've had the same problem with my first Tilt. There's multiple threads that detail this known problem. Some seem to be due to bent pins, some are general hardware failures (possibly the USB controller). There are some HardSPL images out there that have a "force usb" option enabled. This never worked for me, but it might be worth a shot for you.
...a word of warning....
If you end up reflashing your phone (via MicroSD) and the flash goes bad, you may be stuck, as many of the solutions for repairing a bad flash require you to USB sync. My first Tilt was a victim of this after a bad stock ROM flash that left my device without audio, and unable to flash via MicroSD.
replace usb board
you need to replace your usb board. It will run you less than $10 if you do it yourself. you can get the board on ebay
really? 4 years later?

HTC Diamond USB error

Hello everyone,
I'm having a problem with my Diamond. When I attach it to a USB port nothing happens. No 'hardware found sound' or what so ever.
I tried several other pc's with no result. It does charge when it is connected and the phone asks whether it needs to be in USB mass storage mode or in Active sync mode. I havent found anyone with the same problem so I'm afraid it is a hardware failure?
I tried:
-Soft/Hard reset
-Several computers/usb ports
-Disable Advanced Network capabilities
Does anyone have some tips that I haven't tried already that could help me out?
Thanks for your time!!
Disable Advanced Network capabilities under USB->PC in your Settings, that should do it.
I tried that also. With no result yet. Any other tips maybe?
First, check your cable for any marks that resemble rabbit bite marks or alligator bite marks.
No, seriously, check the points where the cable goes into the plugs for any obvious signs of damage, then check the cable itself.
Maybe, try using a different cable, if that doesn't work your Diamond most likely has a problem. If the different cable works, your cable is a goner.
Although I think there's quite a small chance that that's it, it's worth trying, right?
Use the 6.1 version of the Windows Mobile Device Center under Vista
Thx for all the tips. I didn't manage to get it working though
When the phone is connected to the charger it asks if I want to use activesync or usb mass storage. A friend of mine has also a diamond and his doesn't ask this. My conclusion is that it is broken
Damn I got this phone as a replacement for my broken K850i from my provider...They will go crazy when they see me again
Hi,
I have the same problem.
My guess is that it all started with a non compatible charger.
When charging it asked for active sync or disk.
After that the problems started, active sync doesn't work anymore.
Sometimes it workes when advanved networking is off.
Tested on different pc's, freshly installed.
Complete factory settings, notting works.
If synchronised by bluetooth it works.
I'm affraid i have to send the phone back for repairs and trow away the bad charger.
I never used a 3rd party charger.
Is there a way to update the firmware via bluetooth?? Because i'm still using the old slow version...
Same problem here. I've used my tomtom USB car charger. Is this a guarante matter, or do i have to pay for the repair?
You may have set the default connection to other than ActiveSync when first seeing the pop-up.
Go to 'Settings' 'Connections' and select 'USB to PC'.
Ensure ActiveSync is selected.
If you want the pop-up to display when the USB is connected (its good when you want to use your internal micro-SD as a memory stick), check the box at the bottom. You can select ActiveSync, Memory or PC Modem from when it appears on connection but when you just ignore it, it will perform whatever default selection you wanted last and then dissappear.
If all else fails perform a hard reset!
I've tried /soft/hard reset. No luck..
Can this be a hardware related fault, or could a ROM flash resolve the problem?
Transfering video files via BT is a pain in the a*s...
i would try a flash before returning it. You can probably dl an official 1.93.xxx.xx from htc and try that. You don't need hard spl and all that for those ROMs.
I have the same problem:
no connection at all from the PC-side. The Diamond comes up with the ActiveSync/Discdrive question and starts charging, but nothing else.
I did use external chargers that also trigger the ActiveSync/Discdrive question.
Update:
Oops, it seems fixed after a soft reset.
Same problem, diamond would not connect to PC.
Solution: Warranty repair---> they changed the motherboard, and everythings is good. Everything was free.
Edit: But now I have a different problem. I connect diamond in to PC, everything is good, but about 30 seconds after, mobile center looses the diamond, and sync won't work. Any solutions?
I have the same problem before. My Diamond USB cannot be recognised by the PC. Took back to repair and now working. But one PC still cannot recognize the diamond. The service centre told me they have reset my unit and when came back, everything has been cleared. I suspected a full reprogram of the ROM.
I have the same problem
I cant have any connection to the PC
so, no solution but the service people
USB Connection ERROR
I have the same problem. No computer seems to be able to connect to my P3700. I tried DL new ROM but I don`t know where my device came from. On HTC site from HK, which is the only one where I found a neutral Diamond with no carrier associated like, Sprint , Telus, or the like, its says The ROM Code can only be updated on HTC Touch Diamond Hong Kong English Version Device
Does anybody have a clue how to find out where my device was originally intended to be marketed? My ROM is 1.93.456.2 WWE dated July-10-2008? Do the the numbers 456.2 mean anything?
Help is highly appreciated!!

Won't sync with PC
Hi,
I have the same thing where it won't sync with any PC and i've tried all the "other" fixes and I've sent it to the service people to have a look.
Thing is, because I thought it was an issue with the usb connector I thought I would have a poke around with it myself and i could see one of the prongs looked like it wasn't making contact. To cut a long story short whilst i was trying to fix it the plastic tab in the mini usb connector came out completely
Service people are now saying that I've abused the handset and want to charge me £70 to fix it. Now to be fair, I have made it worse, but in my defense it was only because a fault had occurred that I started to dabble.
I also reported to the service people that the led light under the "end call" button had stopped working completely. This was definiatley not due to miss use.
I'm wondering if this led is on the motherboard like the usb connector is. If so, can i be cheeky and just ask them to fix the led and not the usb? but by default because the m/b would be swapped out then the usb would be fixed anyway?
If you looked at my phone it looks well cared for (which it was!!!) and its not like I've hammered it in anyway.
Anyone have an opinion or know if the led for end call and the usb port are both on the motherboard?
Thanks

Bad Usb Port

I belive I've killed my Usb port on my Tilt. I can still charge it, but it won't sync or pass data to any PC I have, I've tried various cables, and even cleaned the lint out of it and still Nada.
Is it a major mission to replace the USB port?
Any input as to which Pins are needed to transfer data? I've looked at it under a microscope and it looks like the middle pin is either pushed down or back.
Thanks. I'll try to post pics of it if it helps, and even pics of the phone open too.

There are many (many many many many) similar issues, that's not the first time. Use the search function with key words like "usb broken" for example.
E.g: http://forum.xda-developers.com/showthread.php?t=354472
You might want to have a look at this repair website (cited in the previous thread): http://www.pocketpctechs.com/main.asp?area=home
Unfortunately I came across a ton of posts about USB's but nothing about not bad USB.
I'm interested in fixing it myself, not sending it out as well.
I'm reading up on the links you've provided, thanks.

Help with disconnects/unable to connect

Hi,
My Diamond is really unstable when it comes to syncing it with my computer. Some times it works fine, other times it won't even connect (not recognized). When it does connect, it usually drops the connection before I can even sync anything...
Anyone know how this can be fixed? One of the posts I found suggested a bad data pin on the phone...:S
I get the same - please help us!!
USB Cable
I've had the same problem before but it turned out to just be the USB cable that came with the phone. Have you tried a different cable to see it that's the issue?
Graham
I've tried two different computers, three different OS' and three different cables :S Was hoping that an HTC adapter I had lying around would fix it, but doesn't look like it :/
Thanks for the reply, though
