Problem on installing Android usb driver in windows 8 64bit

Reason: Device not supported in usb driver provided by Android SDK

Solution: Find from Device vendor for signed driver or

find the device info and add it into usb driver file provided by Android SDK

example case for HTC Desire z:

1. open <androidSDK path>\sdk\extras\google\usb_driver\android_winusb.inf

– add lines:

;Desire Z
%SingleAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C91
%CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C91&MI_01

under section [Google.NTamd64] if using 64bit or [Google.NTx86] if using 32bit

2. shutdown /r /o

– pick reboot with troubleshooting with advance option- startup setting

– when boot up, choose option 7 i.e. disable signed check

– open windows explorer, browse to <androidSDK path>\sdk\extras\google\usb_driver\ , right click on ‘android_winusb.inf’and click ‘install’

– connect android device via usb, and run “adb.exe devices” to confirm it’s detected.

3. restart OS back to normal mode.
