RX300 / RX-RDP USB Peripheral device redirection recommendations.
Please refer the KB article on How to configure USB peripheral device redirection policy for RX300 and RX-RDP:
In addition to the information on the above linked article, you may need to disable the policy: Do not allow supported Plug and Play device redirection.
This applies to Generic USB redirection of peripheral devices in RDP sessions on Windows Server 2016/2019 and Windows 10
In Windows Server 2016/2019 and Windows 10 the said policy setting is enabled by default (when not configured), which prevents the Generic USB redirection of the peripheral devices to the above mentioned operating systems.
This Group Policy setting can be found using gpedit.msc, under Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection.
Please be sure to disable this policy in order to be able to use the Generic USB redirection of RX-RDP peripheral devices in Remote Desktop sessions.
