Package: nut
Version: 2.6.1-2
Severity: important
After upgrading nut from 2.6.0-2 to 2.6.1-1 nut did not start properly. This
did not change in version 2.6.1-2.
Underlying problem was that driver did not start becouse it could not access
USB device.
Executing "/lib/nut/blazer_usb -a MyUps" produced following error:
Network UPS Tools - Megatec/Q1 protocol USB driver 0.03 (2.6.1)
Can't claim USB device [0665:5161]: could not detach kernel driver from
interface 0: Operation not permitted
I traced problem to removal of rule
# Krauler UP-M500VA - blazer_usb
ATTR{idVendor}=="0001", ATTR{idProduct}=="0000", MODE="664", GROUP="nut"
from /lib/udev/rules.d/52-nut-usbups.rules.
Adding separate rules file with just this rule solves the problem for me, but
this was not the only rule that was removed.
My UPS model is Mustek PowerMust 848. I guess anybody with same or similar UPS
model will encounter this bug.
