well, for one, my program doesn't work :-), it works with the RS232 version.

so i started to poke around, and did some reading, and as far as i could tell,
the read(2) has to be initiated by the host, but my knowledge of usb is close
to zero - it was zero 2 days ago, but still looking for some better docs, and
polish my english - as far as i remember interrupt is not polling, but the
ohci docs imply that :-)
