right, but the fix made for the kind of devices you have (ie not fully
complying to USB standards) broke other devices / features.

the right fix would have to be in libusb, but since we're still on 0.1
(which is not maintained anymore), the solution may come from the port to
libusb 1.0.

After upgrading to Natty, I have the nut-2.6.0-1ubuntu3 package and it

could you please do the following test and send back the output:
- first, stop nut
- then "export USB_DEBUG=3"
- start the driver using "sudo /lib/nut/usbhid-ups -DDDD -a <upsname>"
where <upsname> is the one from ups.conf.

- the output of "dpkg -l '*libusb*'" would also be useful.

cheers,
Arnaud
