In our setup (OMAP3 EHCI host, keyboard, mouse mass storage and BT dongle devices connected via several hubs) keyboard fails to initialize during the bus scan (stalled endpoint while get_descriptor/64) and after that keyboard is unusable (even in Linux) until power off/on.
Increasing the delay after port reset from 200ms to 260ms solves this problem.
