USB redirection

I'm evaluating Parallels RAS as a possible replacement for Citrix. So far most things run inside our published desktops as expected.

Unfortunately, we rely on usb redirection on wyse thin clients when accessing a published desktop to provide usb functionality to staff. USB redirection does work for Citrix, so this isn't a limitation on the wyse terminal.

I've followed the few kbs I've found on parallels documentation. I've made sure usb redirection is enabled on the wyse terminal. I've added a group policy on the windows server that provides the published desktop that enables remote desktop rdp usb redirection.

The wyse terminal registers the usb when it's plugged in. There is just no redirection happening.

Has anyone else had success getting usb redirection working with parallels on wyse terminals? if so, I'd appreciate any insight or documentation you may be able to provide.

Thanks!
