We have just released Fanaleds 2.2h. This should hopefully fix the issues some rFactor and Assetto Corsa users encountered.
-Rewrote rFactor plugins in an attempt to get them stable again
-Added SymProjects ProShift support (probably, completely untested)
-Some minor optimizations regarding AC and USB, might solve some of the weird problems
