[Nut-upsuser] Problem with NUT and an Eaton 5PX UPS, usbhid-ups won't start

[Kris Jordan]

I couldn't get a 5PX1500RT to work with NUT 2.6.5-4 on Windows using 
usbhid.

In your Log,
    4.805060     No appropriate HID device found
    4.805087     No matching HID UPS found

I got those on my Windows test machine.

I recently compiled NUT 2.6.5-4 on Centos 5. It seems to be working with 
usbhid-ups. Not sure why it doesn't on Windows. Though, I still do get 
some errors,

Warning: report descriptor too short (expected 2580, got 2312)
libusb_get_report: Connection timed out
Can't retrieve Report 28: Connection timed out
libusb_get_interrupt: Connection timed out

and

USBDEVFS_CONTROL failed cmd usbhid-ups rqt 161 rq 1 len 2 ret -110

kernel messages. A higher pollinterval doesn't eliminate that. Seems to 
only happen when the driver starts.

Try updating NUT to 2.6.5, you could also try mge-shut (I'm using the 
newer mge-shut driver) over serial, that seems to work fine (on my 
Windows machine anyway).
