USB device is not recognized error.

Hi all,
I'm experiencing the above problem. It started last week when I tried to reflash the firmware to a third party firmware. The unit could power up as normal, wifi, bluetooth all working fine but not the USB. I've tried installing a utility which switches the mode from RNDIS to USB but it still failed .. hard resetting the device does not help either. Is there a way that I could revive the USB connection? I couldn't sync my contact etc at the moment with my PC.
BTW, currently I'm on Onyx Jr. 4.1.2. I could not update to any firmware due to this and I don't have microSD to SD converter which I could use to copy the firmware to the microSD.
TA.

Disconnect sync cable. Reconnect to different usb port on computer. Right click ActiveSync in taskbar. Click connections. Make sure "Allow USB connections" is checked. If above fails, uninstall usb adapter in device manager, reboot computer. It'll reinstall with stock drivers after reboot.

It may happen due to faulty USB cable. Try and use another cable and on some other computer and check

I've tried all that I could think off including removing activesync and reinstalling it back. I've few miniUSB lying around and I've tested many of them but my notebook just did not want to recognized the htc touch. I've tried using those cables with my wife's tytnII and they worked .. could it be the hardware problem inside htc touch itself?

Tried with a new USB cable found in my newly bought GPS and if I reseat the cable properly, my notebook could recognised the htc touch. So I guess a new cable does help.. thanks all for the help.

[Q] HTC Magic 32a: USB not responding

Hello!
I've bought used Magic few days ago, and last night I wanted to root it, but when I try to connect it with computer - nothing! No USB icon on Magic, no new device on PC, just charging. I have original 1.6 android on it. Tried 4-5 different USB cables.
What can I do? Is there any way to fix it? Can I do rooting and flashin new rom from SD card, without usb?

turn on usb debugging in settings/applications/development

Already tried that. Doesn't help.

BUMP
Anybody?

could be a problem with your usb port on computer, try another port or try the phone on another computer and see what happens. also did you try the usb headphones ? are they working fine?

uable to get usb connection working

since around a week ago my phone has not been able to connect to the usb ,
it does still charge via usb cable from the pc but the cable is not detected for mass storage ,kies or usb debug .
i know drivers are ok on pc as my wifes phone still connects fine .

Have you tried the debugging mode?
EDIT : Try installing the usb drivers from my signature.

ive tried debugging mode no different , i can even select - deselect usb debugging whist the usb cable is connected .
the usb drivers from your sig are for windows x64
my wifes galaxy s is detected by the computer fine ,same usb cable and port

Can't you get hold of a friend's usb cable?

hi i have multiple usb cables here 2 original samsung galaxy cables plus multiple other micro usb cables . non of which work with the phone . not to sound ignorant but dont you think i have tried the obvious things first ?

Try a wipe/reset
If that doesnt work, try an other rom .... Stock or non-darkyy
If that doesnt work, im afraid there is a hardware problem

DID you try to put a RIGHT cable into a WRONG hole???

You are not alone, I have exactly the same problem, but wrote it off as a hardware problem, because it started after my son (9 months and teething) gnawed on the phone for some time...

ok tried different roms etc no luck must be hardware related going to open the phone tomorrow and check the usb socket . only really worried incase i need to use odin to recover after a bad flash , or incase the usb decides to die completely and i cant charge the phone

Hey Jona29 i had the same problem some time ago i solved it by changing usb port (preferably one direct to motherboard) while pc is off then start it while in download mode and flash with odin.
Good luck bud, i know how frustrating it is

UPDATE ! fixed the phone ,yes it was hardware not software at fault . dissasembled the phone and removed the board with the usb connector on .
heated the board around the connector with a pyro pen to reflow the solder
let it cooled and then reassembled the phone .
powered up phone and connected usb lead ,computer recognised phone and phone recognised usb connection
probably took me 30 mins to complete the task.
better than say a 4 week wait from samsung

Slick. I have taken my phone apart for USB problems as well, but I would be scared to try to reflow something on the PBC. The connections are so small.
I have had the USB issue as well but it always seemed to be the cooked ROM iI was using.

I had the same problem, after using DXJPA ... every time i connected the phone (even in boot mode) i received "USB device not recognized" ... I don't know what worked in the end, but i tried a lot of things: I bought a new cable (same problem), I used another computer (same problem), I tried on W7 x64, W7 x32, XP SP3 (same problem), uninstalled and reinstalled Kies, I uninstalled and reinstalled an older version of Kies, changed the phone form a computer to another, played a lot with USB ports ...
After 2-3 hours of pain, Odin saw the phone ... flash it to JPY and no USB problem anymore ...
Maybe this will help someone

[Solved] [Q] USBFlasher Mode not operative [drivers?]

My main issue is drivers. I ended up formating my computer with a fresh install of Win7 64-bit few weeks ago, but did this with android on my phone. So now I have a dilemma.
I cannot get drivers anywhere [online] that will let me go into any USB mode for either:
MAGLDR
or
Tr-Color Screen
So either with magldr it just sits there forever saying USB Wait...[never says usb]
And with tri-color screen it never says USB, if I try different USB ports it says Serial and never changes to anything else.
I think my problem is I need WM back, and sync it with WMDC. The problem to that? I cant even flash WM...
Anyone know of any other way to get the drivers for Win7 64? So I can use USB Flasher or tr-color screen.
Hope someone knows a solution...I have been looking for weeks to a resolution to this problem :-/
Thanks in advanced

Try reinstalling Windows Mobile Device Center.

I tried that, I installed it and it installed a Microsoft Mobile device driver, but it still does not say USB on the flasher mode or on the tri-color screen...
Can anyone find out the name of the driver/device when they plug their phone in and it enables USB (under usb flasher or tri-color screen)? Maybe from there I can search better names for the right driver...

Any ideas? Just trying to see if anyone knows any solution to this...
Thanks

UPDATE:
Ok, so I had a minor cut in my cable, with only the shielding wire coming out a little bit. I luckly had another micro usb in house that I could try. Seems if there is the slightest problem with your cable, get it replaced. MY USB WORKS FINE NOW . Try new cables if you are having serious driver issues (tried it on 2 computers, thats when I said it has to be the cable.). Could be the simple thing.

[Q] USB Mount or Mass Storage not working on MT4G

The probem:
USB Mass Storage not working in Recovery. I tried everything, reflashing different recovery but its not working, it doesn't give an error message. When card is not inside however it does complain. SdCard is fine because I can flash zips that are on it. Tested on both windows and ubuntu. tried another card as well
USB Mount doesn't work in CM7.2 or any rom or nand restore i've done recently. I had Insomnia at some point, then inferno, then cm 7.1, none of these restores work. Again here no errors, I do not even see the sign for usb detection. usb debugging is enabled/disabled no difference. phone however still charges though.
I'm on a trip right now, but I've not had the chance yet to get another usb cable but the two I have dont work.

Its either your USB cable or your phone USB jack mine does the same thing I have to wiggle it to get a good connection cuz my USB cable sucks cuz with others it recognizes it right away.

He has tried two cables, so I would tend to lean toward the port.

i am in the same boat. looks like my charging port is bad. anyway to replace the charging port? i am not good with soldering

it's not ur usb port
it's htc.. htc devices doesn't support usb host feature.
If you have a rom and kernal that do support usb host then try powering the usb as the htc devices do not provide power out.. use usb Y cable

What? He isn't trying to host the connection. He is trying to use his phone as a USB mass storage device.
Where did you get USB host from in his questions?

Hi all,
I am having the same problem, except perhaps with a different cause. My user account on Windows 7 became corrupt and I can no longer log in, so I had to create a new one.
On the new account, my myTouch 4G is not recognized for mass storage/disk drive mode via USB. The USB cable does work, the port is okay, and I've used both with other devices. The myTouch shows as charging when connected to the computer. I have uninstalled and reinstalled all of the myTouch drivers, restarted computer and phone, to no avail.
When it is connected in USB, it shows as generic "Drive F" and is inaccessible. When I check properties it says mytouch4g. When I check "Devices" it is recognized as portable storage. I have tried with USB debugging on and off, and have set "connected to computer" mode to disk drive.
Any thoughts? I thought possibly loading the generic ADB driver again might help, but I cannot get to the stage where I can force it to load that driver instead of the HTC one.
