External drives mounted already before connection do not appear in the remote desktop. Workaround: mapping the directory /media as a drive on desktop. Then the external devices will show up inside the media drive.
Client drive mapping and USB redirection for storage devices should not be enabled both at the same time.
On the one hand, when using USB redirection for storage devices: The USB on-insertion feature is only working when the client drive mapping is switched off. In the IGEL Setup client drive mapping can be found in: Sessions > Horizon Client > Horizon Client Global > Drive Mapping > Enable Drive Mapping. It is also recommended to disable local Storage Hotplug: On page Devices > Storage Devices > Storage Hotplug, put number of storage hotplug devices to 0.
On the other hand, when using drive mapping instead, it is recommended to either switch off USB redirection entirely or at least deny storage devices by adding a filter to the USB class rules. Furthermore, Horizon Client relies on the OS to mount the storage devices itself. Change on the following setup page is required: Devices > Storage Devices > Storage Hotplug. Activate Enable dynamic drive mapping and set Number of storage hotplug devices to at least 1.
