Usb ports not recognized


Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.

Appears to be a failure of the bluetooth module itself. You could try uninstalling it in Device Manager and reboot to allow it to reinstall.
