Wow, I spent several hours today pulling hair wondering why USB redirection wasn’t working at all for flash drives and webcams (just testing performance difference without RTAV). I’m brand new to ThinOS and WMS so I wasn’t even sure what should and should not be working. Glad I came across this thread, now I know I’m not crazy.
I’m currently running WMS 3.3.1 and ThinOS 9.1.3129. The USB redirection issue still exists as of 10/8/2021.
