  1. Go to the official Google website and download from Google website.

  2. After extracting, find android_winusb, right-click and select install, agree to all certificate issues.

  3. Connect the device and execute _flash_fastboot_with_unlock to enter fastboot mode.

  4. Open Device Manager, find the device with "Android Question Mark" icon and click Update Driver -> Browse my computer for driver software -> Let me pick from a list of available drivers on my computer (L) -> Install from disk -> Browse to find the android_winusb file -> select Android ADB interface -> Confirm all the way -> Reboot.

PS: If USB is unrecognized, it is usually due to a problem with the USB cable/port.

In most cases like yours, the problem is that proper driver isn't installed. Check how your device is shown while in fastboot mode. If it's not "bootloader", then you have to install proper drivers. You can get official android drivers for adb from official android website, which will work in most cases.
