I just replaced the ROM on a Qtek 2020i. It took me a day and a half to get it done. I tried everything I could think of to make it work. It got stuck in Bootloader mode and nothing I tried would work.
I finally use a different USB port on my computer and BANG, everything worked fine.
Does anyone have an explaination why using a different USB port made a differance? I'm at a loss to understand why.
Hope this helps others that are in the same situation I was in.
at times windows try to install drivers and it goes wrong
drivers for usb devices are tied to the usb port they are connected
to and moving the device to another port reinstall the driver

Hello good people,
I've got a problem with my Wizard that's been bugging me for a while now and no matter what i try, i can't get it fixed........
Recently i flashed my Wizard to WizFlo2d 6.1.1.2, everything good and all, but the rom is too buggy for me and i want too flash something else.
Only problem is, since flashing that rom, i can't flash anything else, because Active Sync doesn't work at all. It will connect, but when syncing i get lots of errors. The pda also reports errors, but i can't even read those because of it's buggyness. There is a hotfix for this problem but that won't install ¬¬ This all also means i can't flash, not in Vista, not in XP, not in bootloader, nowhere. I keep getting the Phone not ready or Phone not connected error over and over again....
I really hope you can help me with this because my pda is as good as bricked right now, the rom is very buggy and doesn't work and i can't get another rom on it....
USB port trouble
The problem is with the USB port you are connecting to, I had the same problem with WM6.1 ROM's while it was fine in WM5. Make sure your phone is connected to a USB port in the back of the computer not the front. If it still doesn't work, try unplugging any unneeded USB items and see if that frees up enough power for it to work right. You could also try using a different PC. My wife's laptop worked fine even when no port on my desktop would work. My final solution was to get a powered USB hub and plug into that and now I connect and can flash every single time with no problem.

Hmm, weird thing is, i'v flashed lots of WM6.x rom's before without any trouble, and i already tried the back usb port. Haven't tried freeing up all the usb ports yet. I will try another pc though, see if that works. Thanks, going to try this now
This keeps getting crazier, i can connect my phone, browse files, download and upload files, but still can't flash...Even with powered usb hubs and other pc's :S:S There's still a tooltip about syncing i can't read....Can anyone help?
i have the same problem.. as works fine but i cannot flash due to a 260-error. Have used all usb-ports and rebootet everything including my fridge but im stuck with this manilla-without-wifi rom
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.
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 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!
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 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
