    I have tried the Serial-over-USB thing and got the following

It would seem to be the

ret = usb_interrupt_read(udev, 0x81, (char *)buf, bufsize, timeout);

line that is getting the error 2. Is there any more information on 
what should be in there? Or is this the time I have to start trying 
different bits, like putting the usb_get_string_simple in instead?
