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] Windows will not recognize Note 3 anymore, help please!

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks

Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?

Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.

Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?

Thank you! Worked perfectly!

I have the same problem, do you have any solutions ? Thanks.

I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!

please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...

I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!

[Q] No usb after 5.0.2

Hi i have a nexus 7 (2012) everything was working fine until android 5. The device was slow and almost unusable. Then the 5.0.2 update came out and guess what? I updated it and now my laptop wont recognize the device so i tried a different cable and nothing. I plugged the nexus 7 in my second computer and nothing not even the sound that means you plugged something in the usb port. So i went to my brothers house and tried his computer.... the same... nothing. We plugged his nexus 7 (2012) 5.0.2 wich is the exact same device as mine and it works so we thought that it was the usb connector on the device and we switched my connector with his....NOTHING happens. computer wont recognize the device, no sound, no pop-up, no ADB detection. Does anyone have the same problem or a solution on how to downgrade 5.0.2 back to 4.4 without usb cable?
Thank you

Did you tried out to start n7 into fastboot mode and recovery mode?
Is usb not available also there?

fastboot and recovery mode also has no USB. absolutely nothing happens. when i connect the device it charges but the lightning icon does not appear on the battery in the status bar. and its not the usb port on the N7 i changed it.

?????????????????

Same here
I have the same Problem - a N7 GSM with 5.0.2 and no communication via USB.
I have tried different computers with Win7 and Ubuntu14.10. As well as differnt cables. (And all combinations of that work with my HTC M7, by the way)
Under Linux, not even lsusb shows the device, or dmesg shows any connection to a usb device.
To be completly honest, I did not give much love to my N7, I have been using it hardly. But when I did, I have been flashing some differnt Roms and testing different bootloaders so this might be some kind of my fault.

i updated to 5,1 and still the same problem so i assume its hardware related. but i know it is not the USB connector because i tried it on my brothers N7. and it works

Mine is quirky, comp recognizes it and can order boot but sideload and push to device don't work. Its odd.

connectivity issue

hello
i have a problem with my g928f
my issue is that it can not be regognized by the windows
i have tried at my desktop with win 10 and at my laptop with windows 7 and at both says unknown device,
i have tried everything i know of
unistall everything from the pc regarding samsung drivers
install it again , nothing
install smart switch , nothing

noone??
today i replaced the screen with a new one witch had a new usb dock on it and the problem is still here
i can not connect it to any pc.
i cann't flash the stock rom because odin is not see it also

is it possible to be a rom problem????
i can't flash the stock one because of the usb issue
but i think i can download another lollipop rom to give it a try.

Have you made sure that it is set as MTP?
Setting - Storage - USB.

Check if the device gets connected in Fastboot mode. If it doesn't then it would be your USB.

sideload is not working either
usb is brand new and original.

is there a way to flash stock rom via recovery?
