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

Hey guys, just got my Tab a few days ago, its unlocked and its working great. I want to root, but my PC wont recognize it (running win7) and it says the USB device has malfunctioned... wth? I searched through some threads about the drivers, and ive tried 4 different ones, restarted my PC, AND my Tab, with no luck. No, USB Debugging is not enabled. (not a noob, just, simply not working)
Any ideas? I would appreciate it
I just got my tab 3hours ago. I got it to work.
Here are what i've done
1.go to control panel and see if samsung usb driver is there. If it is, uninstall it.
2.disable usb debugging on the tab
3.connect the tab to the computer.
Thats wht worked for me. Hope it helps. And yes, samsung has really got to work on the usb thing.
Unzip and run the attached file. Delete any old unused USB device and delete any Android, Samsung or other related device then reinstall Samsung drivers.

This helped me: my computer tower has front and back USB ports. Back USB ports are directly embedded in the motherboard, front USB ports are a wire run from the case plugged into the motherboard, but the front USB ports are on a different chip.
When I first tried using the ADB debugger with Android, ADB would not even find my device if I plugged the device into the front USB ports. If I move the cord to the back USB ports, everything works properly. Maybe this is your issue?
Thanks guys, I believe I got it working.
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.
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.
Im in England and the phone for S5 for America, how do you find the USB "connection as camera" its not in the notification panel ? im trying to get on Kies, but i cant.

Do you have the usb drivers installed correctly? Or try another usb port/ cable.
IVE put the USB driver in the c drive along sid the KIES and still it says its (USB) not recognised. Is there something else i could use instead ,i didnt like kies anyway.I tried to get airdroid to work (ive had that for 3 years) but it doesnt handle software (my phone) 4.4.2 it only does 4.3. It says FORBIDEN.FAILED TO SEND MESSAGE on my PC.
Most likely you are using an outdated version of Kies. There are multiple versions of Kies, ensure that you install the latest version of Kies. Then open Kies and have it detect your phone. That is by far the easiest way to install the proper driver for your S5 model. After the driver is in place you can close Kies and never use it again. Or uninstall it if you wish.
Do not use an USB hub, connect directly to your phone. If you have ongoing issues, use a different USB cable and port. Ensure that you are using a data cable, not a charging (only) cable that has the data lines shorted. If your PC has USB driver issues in general, then you'll need to resolve those issues first or use a different PC.

KIES V3. The trouble is i cant find the USB i now it should be there in the notif panel but it is not, ive got developer options & usb debugging ticked but thats all, have i got to do anything else (hair pulling time) i dont think so?
1) Should i plug it in the mains or usb on the pc
2) Im using the cable that came with the S5 is that good enough.
3) The S5 sits on a cradle shall i take it of.
4) How do i tell data cable, not a charging (only) cable that has the data lines shorted
5) Ive tried 4 different USB software and it gives the message DEVICE DRIVER SOFTWARE WAS NOT SUCCESSFULLY INSTALLED every time
6) Ive done a reboot every time the drivers are put it

If you use Windows 8(.1) you have to disable driver signature verification to get the usb drivers installed. Here is a tut. https://learn.sparkfun.com/tutorial...abling-signed-driver-enforcement-on-windows-8.

You are juggling too many unnecessary variables. Try to simply that and don't skip checking any of the points.
I have no idea what you mean by plug it in the mains? And at least until you solve this you should not be using a cradle, hub or anything else. As I suggested earlier, connect the phone directly to your computer USB hub. And if you have ongoing problems, try a different cable, USB port or even PC.
Making an assumption that the cable that came with the phone is good enough is counter productive. It's not impossible that it may be damaged or have some problem. Borrow or buy another cable, to eliminate one more possible cause of your issue.
Retrace and double check each step. As soon as you make an assumption that it's not worth checking x step because it couldn't possibly be the cause, you are skipping a possible solution. Make sure that you are using the latest Odin, make sure that you installed it from windows administrator mode, connect directly to the PC's USB port, different cable, etc. If you are methodical, you'll resolve the problem.
Good luck

Have you activated developer oprions and usb debug?

If you haven't given AirDroid permissions to send SMS directly, "FORBIDEN.FAILED TO SEND MESSAGE" might appear. Change the permissions in phone's settings for a try

Thank you for all of your help fffft and the rest it was essential for me THANK YOU.
I've got 5 S7s on my desk, all Canadian variant, all from the same manufacturer all the same model. - SM-G930W8
All are recognised by my PC but one and I can't work out why not!
Plugging the phone into the PC makes no noise from the PC but the phone seems to detect a regular charger not a PC.
I have plugged it in using different cables including the one in its box and the ones used on other devices that were recognised and only this phone doesn't work with any of them.
I have plugged in, unplugged and rebooted many times.
I have set the USB configuration to MTP (Media Transfer Protocol)/Transferring files.
USB Debugging is ON and OEM unlocking is ON.
I have tried booting into stock recovery and wiping cache AND factory resetting.
When phone is turned on "adb devices" returns nothing.
I have installed Samsung Kies and Samsung Smart Switch to reinstall the drivers.
NOTHING IS WORKING!
All threads I find tell me to do the things I have listed above and have people saying these have worked but all of them I had already tried and double tried and nothing is working.
The cables are correct and working with other S7s of the same model.
All the correct drivers are installed and have been uninstalled and reinstalled.
All the correct setting are selected and OEM unlock and USB debugging enabled.
Phone was fresh out the box as were the other four and all cables.
Samsungs apps installed on PC to ensure best drivers installed.
Would really appreciate some guidance or consolation that its not something stupid I'm doing! I work with these phones everyday and this has never happened! Just banging my head against a brick wall trying to resolve it
maybe faulty usb port, my nephew had S6 with the same issue, service replaced usb port and it started
to work with PC.
try download mode and see if odin see your phone.
try to move the cable a lil bit and see if sth appears for a second.

Thanks but unfortunately Odin doesn't recognise in download mode.
Could it be a USB port problem if I used the same port for the other 4 devices and have no issue?
I'm considering sending the phone back to manufacturer to be honest I think it may just be a faulty device or something!
I bet its microusb port fault
Had a similar issue on Windows 10 , if that's what your running let the phone be connected, uninstall the driver from device manager, and then install driver select have disk and select the basic mtp , if this doesn't help connect to Microsoft support and they'll guide you through it , worked for me , my phone used to detect on other laptops but mine , also I could connect other phones on mine but not my phone, hope this helps
same issue here
