Hans Petter Selasky 70ffaaa69c Update USB_PORT_RESET_RECOVERY to comply with the USB 2.0 specification which 
says it should be max 10 milliseconds.

This may fix some USB enumeration issues:
> usbd_req_re_enumerate: addr=3, set address failed! (USB_ERR_IOERROR, ignored)
> usbd_setup_device_desc: getting device descriptor at addr 3 failed,
