Hi, please validate some settings. You need to make sure RemoteFX is enabled, and that on the remote VM that settings; Do not allow supported Plug and Play device redirection must be Disabled.
On your local computer:
Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Connection Client -> RemoteFX USB Device Redirection -> Allow RDP redirection of other supported RemoteFX USB devices from this computer
On the remote host:
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Device and Resource Redirection
Do not allow supported Plug and Play device redirection >> Disabled.
If the local GPO is working, you should in the remote desktop client Other Supported RemoteFX USB Devices >> USB Input Device XXXXXXX.
