Dear Ilya Yanok,
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.
Do we still have this problem?
