Previously the TinyUSB task was run in the ISR immediately after the interrupt handler. This approach gives very similar performance (no change in CDC throughput tests) but reduces the amount of time spent in the ISR, and allows TinyUSB callbacks to run in thread mode. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
