We are testing a 420 thin client and all seems to work fine except when logged into an RDP session to our 2012R2 server farm, usb storage drives/keys are not recognised.
Everything seems to be set ok on the thin client in Local resources and the usb key is recognised when doing a usb diagnose.
Other usb devices are fine , wireless keyboards and mice dongles , etc
Any thoughts on how to get them recognised in windows explorer
