ThinOS 9.x Smart card/Token redirection issue

Hello,

We use currently Dell Wyse 5070 with ThinOS 9.3.3099 and WMS 4.0.

For VDI we use VMware Horizon 8.7 (2209) with Blast/PCoIP protocols.

We are also using a smart card (Hypersecu HYP2003) to authenticate in a clinical application. USB redirection works fine with ThinOS 8.6 but not with 9.x (I have tried different versions from 9.1.1131 to 9.5.4070 and different policies GPO for Horizon Agent/Client ...).

When I force USB redirection (vid-2ccf_pid-0807) the host desktop detects the 'unknown smart card' in the device manager ('unknown smart card' is a normal behavior, the same with the physical Desktop ) but it does not show the smart card authentication window.

Can you help please to fix this issue.

Thanks a lot.
