[Q] New Nexus 7 usb google driver problem

I'm having trouble getting the proper usb drivers loaded so i can root my new Nexus 7. I downloaded the Android SDK, unzipped and expanded the google drivers, but my Vista computer keeps giving me an error like "windows found driver software for your device but encountered an error while attempting to install it". It shows the driver as Android Composite ADB Interface. Please help!!

You need to disable your computer's driver signature enforcement.

1)by the way - delete your device from Laptop`s device manager and unplug and plug again cable to you Nexus
2)download last version of ADB and Fastboot
3)check at storage menu - preference - camera (not mtp)
4)enter in developer item in settings menu and check USB debug - Android `ll show your alert message with mac adress of you Laptop - you must accept it
!!! Do not try to use some other sofware for rooting (this is bad idea)- you must doing it in fastboot by myself!!!

[Q] Missing CDC drivers

I'm trying to install Samsung mobile phone drivers but no matter what I do I miss these drivers when I connect my Samsung Galaxy Y:
CDC Abstract Control Model (ACM)
CDC ACM Data
CDC OBEX Data
CDC Object Exchange (OBEX)
I have googled for solution and I have followed recommended actions (install Kies, install latest drivers, reinstall all, use "have disk" method) on different operating systems (Windows XP, Windows 7) but I got no success.
My phone doesn't boot (I need to flash it with Odin) so I have tried it all in recovery or download mode but I understand it should not really matter as it's Windows issue, not a phone. I'm using original Samsung USB cable.
Could somebody with a working setup could check if they have above devices correctly installed and provide me more information on the driver file? I mean the information from driver details tab in Windows, ie. name of *.SYS file, *.INF file so I could at least check if I have a driver on a disk.
Any other suggestions also welcomed!

Kies is useless & is not required for galaxy y gt-s5360 as it's not supported for firmware flashing on this device so uninstall it
Uninstall any Samsung drivers you have installed from add/remove programmes
Goto my firmware thread at top of Dev section or link in signature
Download & install USB drivers on my thread
Download the firmware from my thread depending on region
Follow the instructions fully
You can manually install drivers if you wish by clicking on unknown device/device with yellow! click have disk & navigate to where you installed Samsung drivers eg c:/programme files/Samsung

It has finally worked (Windows XP)! I have just installed drivers and followed your instructions (with download mode, not recovery mode). Initially I had other unrecognized devices (very generic usb ones) but after a few attempts (usb plug out, usb plug in) the phone has been detected successfully and I managed to flash it. Many thanks!

Sorry, I forgot to mention. I had also removed a battery.

I have the same issue, Could you please paste the links for downloading the drivers.

Windows 10 USB drivers for ZUK Z1 recognized

Hi everyone.
I have a problem to install usb drivers : I installed the usb drivers from this thread http://forum.xda-developers.com/zuk-z1/help/files-zuk-z1-drivers-qpst-roms-twrp-t3221629, but always no mass storage available (in device manager, just D:/ in mobile devices and COM3 COM4 and unknown peripheral in other peripherals).
I I put the Media Feature Pack for Windows 10 as it's said in the same thread.
In MTP mode, D:/ and Z1 in mobile devices, Z1 available in computeur but all the files transferts are avorted before the end !
I'm with Windows 10 Ultimate.
How can I do please ?

It's ok, I just reboot Windows 10 while Shift key pressed, then reboot options, reboot again and F7 (no verify drivers signature).

Win 10 x64 - Motorola Device Manager failed to install the correct USB driver

So i finally got around to setting up my laptop anew, and i ran into a little snag. I've installed the Motorola device manager 2.5.4.
My XT1562 is not correctly installed as such when connected... (yes, in PTP mode, adb enabled too)
The phone knows it is connected by USB and charges, it works fine on other PCs
Reinstalled Device Manager, nope
Trying different USB port didn't help
Tried different USB cable for the heck of it
Device Manager shows Android Device "Motorola ADB interface" and one unknown "MTP".
Device shows:
The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.
Using the auto update for drivers doesn't work. Manually Specifying the folder for the Motorola Device Manager doesn't work, i checked, there are no drivers lying around in there...
To manually specify the driver i would have to know exactly which device that thing is supposed to be. Hm actually let me check that on the other PC brb
EDIT:
Well, ive never even installed the motorola device manager on the pc (win7 x64) and it just works. Does have the ADB device as unknown in Device Manager.

If you are using Windows 10 or win 8.1 follow this guide to disable driver signature enforcement

For abd drivers

Then reinstall Moto device manager

I've had them installed with signatures before (It was Win10 x64 before too) no problem. Did they mess that up? Thanks ill try it
EDIT
Didn't work. Rebooted with sigs off, reinstalled 2.5.4, no difference
EDIT2: There was no driver signature warning either

Riiight, after some tinkering (including a driver backup from w7 and restore to w10 solution) i figured out the actual problem. I've installed Windows 10 N, and the optional media pack is required for these drivers to work. Go figure.

Cannot get LG K20 plus to be recognized by every computer

My LG K20 plus will not work and so I am trying to resorting to download mode, but the problem is that every computer fails to recognize it. I have done my research but I still cannot get it to work.
I've already done the following:
Tried different USB data cables
Tried using Windows 7 and Windows 10
Tried using USB2 and USB3 ports
Installed all kinds of drivers, including the official one.
No matter what mode it is on (recovery, download mode, just being turned on, etc.) Windows instantly tells me "USB Device Not Recognized" I'm just really lost and would really love to get my device back in working order.
If this can help anyone figure out my problem, here are the events:
