Whenever I plug my phone into my pc I get this error. I tried 3 different computers and 4 different cables. I installed the Samsung usb drivers and adb drivers and I still get the error. I've had some people tell me the problem could be the cable, the charging port on the phone or the motherboard. What's wrong and how can I fix it?
Hi can you please provide more information on your issue like the specific error message??

Ok...here is my story. I have a really big problem. I have the 10s(same is the advent vega) for about 3 weeks and i couldn't manage to connect it to my computer. I bought a male to male usb cable and when i plug in the tab and do the 2 sec back, 2 sec power thing my computer sees the tab as a unknown device. I tryed all the usb ports on my computer and nothing. I have xp but i tried on two other computers with win 7 and the same thing. I tried to update the driver from device manager ...tried to uninstall and search for new device and the same thing. I tried everything.... read all tutorials tried every usb driver... I ''broke '' my tablet and it won't boot now ...the backlight just starts and it turns off.So I need to connect my tab now badly.... so if someone could help....
Once more.....things i tried:
every usb port on comp
diffrent windows and computers
usb driver update
audi
vega tools
10000000 times to get in to the recovery mode (hoping that the comp would show the apx device)
I didn't get a usb cable with my device so i had to buy one..i found a male to male cable
So if anyone knows a way to help me with my unknown device problem... please do... i'm really sad that my tab is ''dead'' have it for a couple of weeks...
Do you have the device USB drivers?
I can send you the drivers and you can try to see if it works with your device , Not sure if it will fix the problem but you can try.
PM me your email and I will send you the file
same problem here, onluy "Unknown device".
Have the right drivers and tried to manuell select the drivers, but it won't work, see screenshot
I had the same issue, BUY ANOTHER CABLE, IF POSSIBLE DIFFERENT BRAND.
That solved my issue, believe it or not the cable was broken. This will work in case you have all the drivers and entered into recovery mode correctly.
Give it a try.
Hi!
I used to have the same problem with my Viewpad 10s whenever I came from stock version. What I found out was that the driver for advent vega must be a bit different from viewsonics.
Try to use the ones on viewsonics site and then try to flash...
...if not maybe its really a cable problem!
Cheers
Hi all
my USB doesn't seem to work anymore. However I don't believe it is a HW failure.
In Linux, when I connect my I9000 to usb, I see the following in the syslog:
Oct 14 17:17:29 xsdnied kernel: [ 1222.601065] usb 3-1: new low speed USB device using uhci_hcd and address 3
Oct 14 17:17:29 xsdnied kernel: [ 1222.670996] hub 3-0:1.0: unable to enumerate USB device on port 1
This happens both in "Download mode" and if I boot in OS and choose "Mass storage for USB", also in Debug Dev Mode ON.
Also in Windows Odin can't see the device via USB. Windows at least told me under certain condition that a new USB device detected but it failed to recognize it (albeit all needed drivers have been already installed)
The phone is working, but I can't even install CM7.1 on it because of signature verification error that seems to be unavoidable under <3e>.
Any idea how to fix this situation?
have u tried a different pc?

I've tried two. at least one of them was already working via usb with this I9000 both in windows and linux
Have you reinstalled the drivers, or tried another cable?

I've tried another cable. I connect/disconnect several times and once of 20 attempts Windows makes its usual USB-discovery sound, but then says something like: USB-device is either broken or device is not recognized.
Well, just took another SGS1 that we have in our family and tested -- both cables are 100% OK.
Hm, maybe USB is indeed broken and that's it :-/
But how? why? Charging after all works.
Got the same problem bro...
One contact broke on the USB port, bricked my Phone too. I wasnt able to use odin to flash my Phone. The crazy thing is that my phone was able to charge but no connection to the PC.
I sent the bricked phone to an thrid partner from samsung, they flashed my phone and repaired the USB port. No is everything okay.
I tried several things to get the USB to work, nothing helped.
I was trying to fix a camera issue while on holiday with my phone but accidentally wiped some partitions during the rewrite of my rom my dad pulled the cable out and now my phone is totally unresponsive. If I plug it into my windows 10 laptop I get a device descriptor request failed error and I am unable to fix it. From reading an article on androidbrick I would post a link but I don't have enough posts it looks like it should show up as a com port but it does not for some reason all the drivers are installed and I have tried forcing the driver onto the device and it won't accept them. The fix I need is a way to get the com port to display so I can reflash and program the bootloader. I am still on holiday so currently have limited equipment basically the phone, usb cable and my laptop and sometimes wifi.
Any help would be appreciated a this issue is driving me crazy. :crying:

Sorry as this may be not much of a help to you but rather my experience with pretty much the same situation.
I couldn't turn on the phone and there were no signs of life when connecting it to a PC (only a message that USB was not recognized with the same description as you mentioned - device descriptor request...).
I tried to connect the phone on different PCs with different OSs (from XP to Windows 10), different drivers/tools, but there was always the same USB error displayed.
Eventually, I had to return it to the service center (it was under warranty) but they couldn't repair it, so luckily they sent me a new one
I have a bricked Lenovo K30-W I'm trying to fix (freezes on startup). My computer (Windows 10) won't recognise it when I connect it to the USB port. In device manager, the phone is displayed as unknown, with error "Device descriptor request failed". I tried connecting to different USB version ports, I tried installing multiple different drivers and software, but nothing helped. Adb doesn't recognise it as well, even if I boot the phone to fastboot with volume+power buttons. Any other ideas? Thanks.
Update: problem seems fixed. I used another USB cable and plugged it into an older version USB port. It is now recognised.
