If you are verifying a drive using the VID/PID, be aware that sophisticated fake drives often clone the VID and PID of the genuine article. If the VID/PID matches but the drive performs incredibly slowly or corrupts data, you may have a counterfeit device. Always test the actual capacity and read/write speeds against the official Kingston specs.
Legitimate Kingston drives with PID 1666 are – they should never act as a keyboard or network adapter.
The hardware identifier maps directly to a high-speed Kingston DataTraveler 3.0 flash drive series .
