Hello there,
You need the group policy settings if you have clients that need RemoteFX capability. Refer to this link: https://techcommunity.microsoft.com/t5/security-compliance-identity/introducing-microsoft-remotefx-usb-redirection-part-1/ba-p/247035
The following GPOs need to be applied on a client PC: Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client > RemoteFX USB Device Redirection - set "Allow RDP redirection of other supported RemoteFX USB devices from this computer" option to Enabled. Please ensure that the RemoteFX USB Redirection Access Rights are set to "Administrators and Users" for this GPO.
