sent two 0 byte packets to the driver, then it sent
'URB_FUNCTION_SYNC_REST_PIPE_AND_CLEAR_STALL' down the pipe which
seems to come back up as well, and then the UPS turned off.
I'll play around later with what happens in that regard, although it
may be a bit tricky to figure out when the battery is low without
having it plugged in ;-)
Also, about nut-usbups.rules.in... The previously discussed Kebo is in
there with the same vendorid/productid. May be useful to add a comment
there as well (in fact, anywhere Kebo is mentioned), I have a feeling
the Kebo may just work with this driver.
