usb: workaround non-working keyboards.

If the USB keyboard is not answering properly the first request on its
interrupt endpoint, just skip it and try the next one.

This workarounds an issue with a wireless mouse dongle which presents
itself both as a keyboard and a mouse but has a non-functional keyboard
interface.
