I'm trying to get this library to work on a Pimoroni Tiny2350 but am having trouble getting devices detected in the capture_hid_report example. I noticed that by adding log lines (to get better insight into where the code gets to), it seems to get further which implies that perhaps the Cortex M33 cores in the RP2350 run too fast which messes up some timing.

Could you clarify what the current status on RP2350 support is, even if it is as-of-yet untested?
