In current RX-RDP, RX420(RDP), RX300 and LEAF OS firmware versions, it is advisable to not use the generic USB redirection for human interface devices, as it can cause unintentional redirection of the thin client’s system keyboard and mouse too, which in turn will cause inability to use the keyboard and mouse after starting the terminal session. If a human interface device other than keyboard and mouse really needs to be redirected, the custom USB device redirection should be used. Please refer to the user configuration guide above for details.
