Nut upsuser - May 2009 - Cyberpower Value 600E UPS (USB) is not recognized by usbhid-ups under FreeBSD 7.2

Hi,

Have anybody tried Cyberpower Value 600E (USB) under FreeBSD?
usbhid-ups from nut 2.4.1 does not recognize (find) the device on my
machine.

[root at substance /usr/local/libexec/nut]# ./usbhid-ups -a CyberPower -DDD
Network UPS Tools - Generic HID driver 0.34 (2.4.1)
USB communication driver 0.31
debug level is '3'
upsdrv_initups...
No appropriate HID device found
No matching HID UPS found


Any ideas what could be wrong here?

Thanks in advance,

This vendorid:productid combination is supported by nut-2.4.1 out of  
the box, so most likely, it is a permissions problem. Try running

     ./usbhid-ups -u root -DD -a CyberPower

to rule this out. We've had some postings on how to set this up on  
FreeBSD in the past, so browse the archives if this indeed turns out  
to be the problem.

Best regards, Arjen

Hmm... Interesting. I have looked through the mailing-list archives
and encountered that libusb-based
packages such as NUT do not work with uhid* device nodes (where my UPS
currently sits).

I suppose I need to find a workaround.  I will keep you posting on the results.

As you found later, the problem is that the uhid driver grabs the UPS 
but NUT needs ugen to get it before it can talk (unlike Linux libusb 
can't kick the kernel driver off the device).

You can try not loading uhid as a work around and see if it works (it 
should do, make sure you chmod /dev/ugenX* as required).

The actual fix is to add an entry in the blacklist for uhid devices 
in /usr/src/sys/dev/usb/usb_quirks.c (around line 115) for the vendor/id 
of your UPS. I think you also need to add an entry 
to /usr/src/sys/dev/usb/usbdevs for the UPS itself. That requires a 
kernel rebuild BTW.

If you give me the output of 'usbdevs -v' I can whip up a quick patch.
