Nut upsdev - Apr 2010 - Error Message Connecting to CyberPower 1500AVR by USB

I have a CyberPower 1500AVR LCD connected by USB to an up-to-date Debian 
Testing box running nut 2.4.3.

/etc/nut/ups.conf contains the following information:

[myups]
        driver = usbhid-ups
        port = auto

When I run upsdrvctl start I receive the following output:

Network UPS Tools - UPS driver controller 2.4.3
Network UPS Tools - Generic HID driver 0.34 (2.4.3)
USB communication driver 0.31
Can't claim USB device [0764:0501]: could not detach kernel driver from 
interface 0: Operation not permitted
Driver failed to start (exit status=1)

Is this because the CyberPower 1500AVR is not supported by the usbhid-ups 
driver or is there something else misconfigured on my system?

NUT wasn't properly configured. Search the archives for "Operation not
permitted" for a solution. This has been discussed many times before  
already. Ask on the nut-upsuser mailing list if you need more help.
