For compiling and installing the Open-source drivers or the Closed-source drivers, see TBS driver installation and Turbosight driver building.

For Linux with ARM CPU in Raspberry PI

WARNING : SHOULD WORKS ONLY WITH TBS 5922 AND NOT WITH TBS 5922SE

The open source driver is available here. For compiling and installing, follow the instructions at http://www.satelliteguys.us/xen/threads/hobbyist-open-source-satellite-receiver-raspberry-pi-2-instructions-and-tips.348466/#post-3641679 .

You mustn't use the remote control because it use a lot of of CPU power.
