Android Can’t Find File android_winusb.inf

The android_winusb.inf file is in a subfolder of the Android SDK directory, specifically:

..\android-sdk\extras\google\usb_driver\android_winusb.inf

In older version of the sdk it was in

..\android-sdk\usb_driver\android_winusb.inf

Depending on the installation and updates you might have both. The file in extras is the newest.
