[Nut-upsuser] usbhid-ups not finding CyberPower PP1100 on Fedora 16
I'm trying to get a CyberPower PP1100 working with NUT on a Fedora 16
system and not having much luck.
Kernel:
3.4.4-4.fc16.x86_64 #1 SMP Thu Jul 5 20:01:38 UTC 2012 x86_64
x86_64 x86_64 GNU/Linux
NUT (installed from Fedora RPM):
nut-client-2.6.4-1.fc16.x86_64
nut-2.6.4-1.fc16.x86_64
libusb:

This is what shows up in /var/log/messages when I connect the UPS:

The permissions of the USB device seem to be correct according to the
udev rule:
# ls -l /dev/bus/usb/001/
total 0
crw-rw-r--. 1 root root 189, 0 Jul 20 14:33 001
crw-rw-r--. 1 root root 189, 1 Jul 20 14:33 002
crw-rw-r--. 1 root root 189, 2 Jul 20 14:33 003
crw-rw-r--. 1 root root 189, 3 Jul 20 14:36 004

crw-rw-r--. 1 root dialout 189, 8 Jul 20 14:34 009
If I run with usbhid-ups with the -u root option, I get similar output,
except that it is able to open and discard the other USB devices without
getting the Permission denied errors.
I saw a report of a similar problem here:
<http://lists.alioth.debian.org/pipermail/nut-upsuser/2007-October/003259.html>
but there isn't enough info for me to solve this problem.
I don't think there is another driver bound to this device and if I try
to force an unbind:
# echo >
/sys/devices/pci0000:00/0000:00:12.2/usb1/1-2/1-2.4/driver/unbind
-bash: echo: write error: No such device

Cyber Power UPS[...]> wDescriptorLength 90 > Warning: incomplete report descriptor > Report Descriptor: (length is 7)The fact that the kernel is printing a timeout error means that something wrong is going on well before NUT tries to attach to the device. What I would do is try to find an older Fedora live CD (or even a Knoppix one, if the kernel versions are close) and try to find the latest kernel which doesn't trigger that timeout error in dmesg. Or maybe it has been fixed in a later Fedora kernel - but I saw a 3.4 kernel mentioned in a Debian bug report with the same error message, so it's hard to say. Hopefully lsusb will be able to retrieve the descriptors if the kernel doesn't trip over them, and if that works, NUT also stands a fair chance of reading the descriptors as well. -- Charles Lepple clepple at gmail
