Wyse 3040 Live USB-Stick Redirection to Citrix Xendesktop Session does not work

Hi Folks,

when we Plug-In a USB-Stick during a live Full-Desktop-Citrix-Session, the USB-Stick/Harddisk does not show up in Explorer.

ThinOS-Version: 9.4.3087

Bios Version: 1.2.5

Citrix Workspace App: 23.8.0.39.1

Citrix Release: 2203.0.3000.3300 on Microsoft Windows Server 2016 DC-Edition as Terminalserver.

When we start a new session on the Wyse3040 with the usb-stick already being plugged in before startup of the citrix session, then it shows in Windows-Explorer and is fully accessible.

With an Igel Thinclient (different manufacturer) it works live in the same environment. So we think that the Citrix-Policies/Environment is not the problem. Are there any known problems or is there a special setting for these?

Thanx in advance,

Marco
