When Linux HID driver binds the USB endpoints of the adapter, 'lsusb' fails to read all the reports and prints ** UNAVAILABLE ** Detect this case and alert the user, providing also the proper command to unbind the driver before running the script again. Put this test at the end of the output, so user can easily see it.
