[Q] USB Driver not working in Win 7 64

I have a Sprint Nexus S 4G and a Samsung Galaxy Nexus Verizon. I absolutely cannot get the USB drivers working on Windows 7 64 ever since I upgraded both to Jelly Bean 4.1.1.
I have installed the latest Google USB Drivers (revision 7). I have also tried to find drivers directly on Samsungs website. I found download pages for both phones but it only listed manuals for download. No drivers.
I have also installed this: ADB/FB/APX Naked Driver: http://forum.xda-developers.com/showthread.php?t=1766220
When either phone is plugged in, I get the taskbar popup saying that the USB Device was not Recognized. I can see in the Device Manager under Universal Serial Bus controllers that "Unknown Device" is there, with a yellow exclamation mark. It goes away when I unplug the phone, so this is what shows up for either phone when I plug them in.
I have right-clicked the device in the Device Manager and went Properties > Driver > Uninstall and remove the device's driver. Then re-plugged in the device, then going back to Device Manager > Unknown Device > Update Driver Software > Browse my computer for driver software and then pointed it to either the Google USB Driver or the Naked Drivers from above. Both result in the message:
Windows has determined the driver software for your device is up to date. Unknown Device.
I have restarted my computer. There are no other devices in the device manager with exclamation marks. I have tried multiple USB ports.
I used to have the drivers working fine a couple months ago when I was running Ice Cream Sandwich.
Does anyone have any clue what I should do next?

If you would read my original post you will see that I have two phones: A Nexus S Sprint 4G and a Verizon Galaxy Nexus. I have the same problem with both phones. I am guessing I have a driver issue, so if I solve it for one it will probably solve it for the other.
Any help or direction you could give would be greatly appreciated.

[Q] Droid Razr HD XT926: Motorola QC Diag port driver install

I can't get my phone to appear in (Win8.1) Device Manager as a Moto QC Diag/COM port. I'm using the (Moto) v5.9.0 drivers. I've tried installing the drivers, not installing the drivers, and updating the drivers manually. I never see a Moto QC Diag port option. If I install the drivers automatically, I see Mot Composite ADB Interface, Motorola USB Networking driver, DROID RAZR HD (under Portable Devices). I'm booted into BP Tools, USB debugging is on, my SIM is out. What am I missing please? Thank you in advance.

Thanks. Ya, I tried the Motorola Device Manager 2.4.5 file. Swapping out to another driver package hasn't resolved the problem. I've also tried on a Win7 Pro machine directly hard wired to my modem. Same problem with it.

[SOLVED]
first, THANK YOU dragonhart6505 for your youtube vid how to install motorola qc diag driver for unlocking motorola droid razr m/hd (xt907/xt926). your words "hit vol up so phone boots properly" was what i was missing.
let me explain as i know i'm not the only poster with this problem, i just haven't seen a solution posted. till now. it has taken me weeks to find the answer.
i thought i was booting into bp tools mode. i did the three finger salute. i scrolled to bp tools. let phone boot and plugged it into usb port. no qc port (not even one that needed a driver). couldnt create a virtual serial/com port either using hw vsp. got a lan error. cdma workshop stated no answer from my phone. i could ping the ip though with no errors. all because i wasnt in bp tools mode as i thought! UGHHHHH!!!! after scrolling to bp tools, hit vol up (no dont scroll to factory reset). youll see when you do it. now i can manually install the qc driver.
the other thing i learned along the way was that with windows 7/8 (yes, and 8.1) the qc diag driver must be manually installed.

The 2.4.5 driver has motport.inf dated 2013-03-19. So anything newer than this will require manual installation. If one knows the PID for the device (in Device Manager / device / Details), one can edit motport.inf to simplify installation.

This is the officail Motorola QC Diag port driver .

No Android devices even seen in Windows 10, let alone recognised?

Afternoon all,
Have been out of the rom'ing scene for a while...
I have a number of devices (Galaxy Tab 2 10.1 and Nexus 7 2012, to be exact), that I want to flash a new ROM onto (the Tab's stuck in a boot loop, the N7's due for Dirty Unicorns Nougat Rom).
All pretty straight forward - I've done it in the past - BUT...
Can I get Windows 10 to even *see* new hardware's been connected, let alone recognize it?
Can I fook
To confirm, I plug the USB between the PC and the device, and all that shows this is connected is that the device realises it's being charged, no "ding ding" from Windows, no USB confirmation from the device...
Both devices have USB Debugging enabled.
Have tried different USB cables
Have tried different USB ports
Have tried - many! - different USB drivers, including that from both Asus and Google's own dev kit.
Have ADB installed, "adb devices" shows no devices (blank).
The thing that's really pi**ing me off is that this is such a basic thing to be stuck by, I really cant figure out what I'm missing!
Any help appreciated gents...

Windows 10 is very buggy. Download lobit Drive Booster to see if you are missing any driver for your pc. Your pc is probably missing some drivers for the motherborad or outdated. If this does not work, clean install windows 10. Let windows 10 install all the drivers for you while it is installing. Best method. Good internet connection required.

its damn easy,the problem lies in Windows,just boot into repairmodus/system recovery its the blue menu for troubleshooting,there u choose Startup Setting and there u choose number 7,thats for disabling the digital driver signature checking,after the reboot all is fine,boot note u must do it everytime new after reboot.
please next ask and post in right section,thanx.

Nvidia USB driver (ADB and Fastboot) is the only one that works for me

D820 "Unkown Device"

Hi, I have a problem here, I bough a very, VERY cheap D820 to a guy I met a few days ago, he told me that he was trying to root the phone and he somehow bricked it so he was selling it half priced, anyway, the problem is that I cannot get the phone to be recognized by any PC running Windows OS or Linux based OS. Linux does nothing at all, and windows says "Unknown Device" every time I connect the device.
I downloaded Google drivers, Android SDK Drivers, Universal Naked Drivers and had no luck at all, windows says the best fitting driver is installed allready (Unknown Device). Also there's no OTG detection either. I can only charge the phone but there's no data transfer of any kind, I've even tried with different usb cables with no luck.
I noticed that the device have installed TWRP 3.0.2-0, the OS instaled was Official 4.4.2 and there wasn't any SMS app installed, not even Google Play or any file explorer app so I went to my other phone, downloaded NitrogenOS along with Pico GAPPS, did a full wipe (DATA, DALVIK, CACHE, SYSTEM) and flashed the ROM and GAPPS. The phone booted just fine, there's no issue with the OS, WiFi works very well, also LTE and H+, bluetooth, I mean everything, yet, the problem persist, I cannot get the device to be recognized by any PC.
Can anyone help me? I don't know what to do next.
PS: I can access bootloader and recovery without any issue yet, adb and fastboot doesn't recognize the device even with debugging turned on.

Sounds like the USB flex cable in the phone is damaged.
Tried different USB cables and USB ports?

Yeah, I tried 4 different fully working USB cables (tested them on my Motorola Moto G xt1032), I think the micro USB port on the Nexus its ok because I can charge the phone normally without any problem at all, the issue comes when I try to connect the device to any PC or OTG adapter to transfer files and such.

I believe It's possible that the phone USB flex cable is damaged even though it charges but will not transfer data.

Agree, most likely the USB port. Not a difficult or expensive part to replace.

Unable to Connect my Galaxy Tab 2 p3100 to laptop

While connecting my tab to PC (Windows 11)
It's showing USB device not recognised. I already tried reinstalling the drivers and replacing the USB Cable but to no avail. Can someone help me out?

If it failed after replacing the cable and you are sure the drivers are working then it's possible that the port is broken and there is nothing you can do about it unless you bring it into a repair shop. At most you can share files through internet, Bluetooth or SDcard if this happens.

Hey. Thanks for the reply! I will give my tab for repair shortly. I just have a couple more questions.
1. My Laptop is running Windows 11 and my PC is running 10. I don't have previous versions of Windows. Is Windows 11/10 responsible for this in any way? i.e. will the device be recognised in computers running older versions of Windows? (I have already tried the fixes mentioned in Windows forums for "USB Device not Recognized" but to no avail).
2. Is there any way to access Download Mode, root, install a custom recovery & ROM without using the USB cable ?

Windows is not at fault. I am using windows 10 myself and everything works as expected. If it was at fault then it didn't manage to find a suitable driver in which case you have to do it manually.
Also from what I know you are not able to flash a custom recovery through the SD card in download mode. I believe it has to be done through the cable. But if you already have a custom recovery installed you can install a custom ROM just fine with an SD card

About no. 2., you may try this method to first root, then install TWRP, and then install custom rom. But please read the instructions and NOTE carefully.
