I have two HP Folio 13-2000. For some reason the right hand usb port is not working so I only have one usb port. For a while it seemed only the left usb port was working. I have disabled and then enabled the usb drivers with no luck. I get no error messages since nothing seems to work on the port. I have tried wireless mouses, dvd player, iphone connections, etc. what other options would you suggest?
