Basically much like Ruud has observed: both machines (PC and C64) will
appear to hang. The tbb value I use is 100us and it seems to be quite
critical to maintain this.

Perhaps there is enough software latency that means you have a delay in
anycase... can't comment without knowing what the C2N232 code does (never
looked it).
