In GRUB to check status of USB transfer we use
grub_usb_err_t
grub_usb_check_transfer (grub_usb_transfer_t trans, grub_size_t *actual);
Which either returns an error (on failure), GRUB_USB_ERR_WAIT (if not
yet completed) or 0 and sets *actual if completed
How does that map onto
void *
usbReapResponse (UsbDevice *device, unsigned char endpointAddress,
UsbResponse *response, int wait)
?
