[U-Boot] [PATCH] usb: increase delay after port reset

[Marek Vasut]

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.

> problem.

Do we still have this problem?
