So the most basic question here is when the usb device not recognized does it generates a registry key with a device ID?
Seems logical to assume it would have to sent every usb device plugged in recognized or not generates an ID. The failure to recognize part is simply a device driver Inf file not matching that ID, which would make the solution to add that device ID to the Inf file to so windows loads the correct driver. Another approach would be for them to create a driver for that device ID that would simply force a usb port reset until the correct ID is detected.
