![]() This change: - Has a small code size reduction. - Should slightly improve overall performance. The old hook code seemed to use between 0.1% and 1.6% of the total CPU time doing no-op calls even when no USB work was required. - USB performance is mostly the same, there is a small increase in latency for some workloads that seems to because sometimes the hook usbd_task() is called at the right time to line up with the next USB host request. This only happened semi-randomly due to the timing of the hook. Improving the wakeup latency by switching rp2 to tickless WFE allows the usbd_task() to run in time for the next USB host request almost always, improving performance and more than offsetting this impact.
