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.
