When running tracelogger with these filter options, it seems that the USREVENTS are not captured. This seems incorrect, 
because USREVENT is different class than the ones that get filtered with F1 to F7. Enabling one of the options also 
starts recording the USREVENT class.

Test it with:

tracelogger -F1 -F2 -F3 -F4 -F6 -F7 -s 3
./start_your_program_that_uses_trace_logi_while_trace_gets_logged
traceprinter | grep USREVENT
