When the NoMachine session is connected from IGEL OS 11, USB devices connected to the thin client are properly listed in the USB device panel. However, once the device is connected inside the session, it's suddenly disconnected in 15-30 seconds. This happens at every attempt to connect the device.

No workaround is available.

The next IGEL OS Release will include a fix for this behaviour.
