Traces from trying to use what seems like a built-in debug mechanism.

%%hook -b f6024
println(r0, r1, r2, r3);

Seems like normal USB activity doesn't generate any logging. It's possible
that this log is meant to be retrieved via USB. Garbage happens below when an
ISR (or maybe the 8051?) flashes the LED. Top half of r0 indicates the trace
location, low bits are type and count information for other args if any.

After resetting the drive and inserting a disc.
Log probably stops as a result of the hook being overwritten.
