[Nut-upsuser] libusb_get_interrupt: error reading from interrupt endpoint /dev/ugen0.1

[John Bayly]

Using an Eaton Evolution S 3000 (usbhid-ups) 2.6.0 on FreeBSD 7.3. After 
checking the debug log for an unrelated reason I saw that it was being 
swamped by the following message:

Mar 23 15:50:57 rack usbhid-ups[65419]: libusb_get_interrupt: error 
reading from interrupt endpoint /dev/ugen0.1: Resource temporarily 
unavailable

The UPS is ugen0 on /dev/usb1

# ll /dev/usb1
crw-rw----  1 root  uucp    0,  37 Mar 22 18:50 /dev/usb1

# ll /dev/ugen*
crw-rw----  1 uucp  wheel    0, 113 Mar 22 18:49 /dev/ugen0
crw-rw----  1 uucp  wheel    0, 130 Mar 22 18:49 /dev/ugen0.1

As far as I can see, everything *appears* to be working properly. Any 
suggestions?

Thanks,
John
