> Hi all,
> A brief summary:
> I have a new Liebert PSA UPS which I wanted to help support my FreeNAS box (a FreeBSD 8 variant). Unfortunately the nut-ups implementation here for the usb hid device doesn’t want to communicate with my UPS.
> I have had a brief discussion with Charles outside of the list and done some digging with Windows XP, SuSE Linux on VM, SuSE linux on a Live CD, and my FreeNAS box in order to try and figure out what is wrong, but I am not expert enough to figure out what.
> On my NAS box there is no implementation of lsusb or usbdevs, which is rather annoying…
> On my SuSE 12.2 running under a VM lsusb fails trying to get the descriptors.
> Windows XP and usbpcap appear to happily read the UPSs device descriptors, and finally…
> SuSE Live CD (i.e. not under a VM) gets the following output (again apparently reading the descriptor OK)

> Trying to start /usr/local/libexec/nut/usbhid-ups –a ups –DDDD on the NAS box gives
> Unable to get HID descriptor (Unknown error)
> i=0, extra[i]=09, extra[i+1]=21
> HID descriptor, method 2: (9 bytes) => 09 21 01 10 00 01 22 ff 01
> HID descriptor length 511
> Unable to get Report descriptor: Input/output error
> Network UPS Tools – Generic HID driver (0.37 (2.6.5)
> USB communication driver 0.31
> No matching HID UPS found
