3010/3020/3040 RDP USB Redirection

We have a mix of approximately 50 WYSE’s, comprised of 3010 (T10), 3020 (T10D) and 3040’s.

All are running ThinOS, no PCoIP and firmware 8.5.024. We are running RDP connecting to a Windows 2019 Server Remote Desktop Session Host collection.

We are trying to use USB webcams and USB headsets with Microsoft Teams. On some WYSE’s, everything works perfectly. On others, the USB devices aren’t recognized within the Windows session. More specifically: some 3040’s work and some don’t. Same is true with 3010’s. So far, no 3020’s work.

I can understand it if only/all 3040’s work, however, that is not the case. Some 3040’s work and some don’t. And, they are all running the same firmware. The same is true with 3010’s as some work and some don’t.

So the question is: why do some work and some not work if they are running the same firmware and wnos.ini file?

Regarding webcams, we have tested with two different models, each requiring a ForceRedirect to work:

; For Logitech Webcam C920 Webcam
Device=vusb ForceRedirect=0x046d,0x082d,0xef,0x02,0x01

; For Logitech Webcam C922 Webcam
Device=vusb ForceRedirect=0x046d,0x085c,0xef,0x02,0x01

When working, the Logitech H390 headsets do not require any wnos.ini parameters.

This is the wnos.ini used by all WYSE’s:
