ThinOS 9.3.X Blast and scanner redirection

Hello,

Is anyone using Wyse Thins OS 9.X with Blast and Scanner Redirection ? I'm trying to make it working but no success. On Windows with Horizon Client, Scanner Redirection is working so I know that the problem is on Wyse. I have tried to exclude scanner redirection in WMS as indicated in the documentation but scanner is never discovered by Vmware Scanner Redirection plugin.

Thanks
