Re: [Nut-upsuser] Cyberpower Value 600E UPS (USB) is not recognized by usbhid-ups under FreeBSD 7.2

Any ideas what could be wrong here? 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. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C signature.asc Description: This is a digitally signed message part. ___ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser

I checked your original post, this should do it.
I've only tested it compiles though :)

So you may wish to add the solution provided by Daniel into the FAQ or at least to mention on the compatibility page (http://www.networkupstools.org/compat/stable.html) that using CyberPower with FreeBSD requires patching the kernel. Better to get it committed to FreeBSD. I have sent a PR with the patch in it so it should be committed. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C signature.asc Description: This is a digitally signed message part. ___ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
Re: [Nut-upsuser] Cyberpower Value 600E UPS (USB) is not recognized by usbhid-ups under FreeBSD 7.2
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). http://lists.alioth.debian.org/pipermail/nut-upsuser/2008-July/004260.html I suppose I need to find a workaround. I will keep you posting on the results. Rgs, forsite ___ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
Re: [Nut-upsuser] Cyberpower Value 600E UPS (USB) is not recognized by usbhid-ups under FreeBSD 7.2
Dear Arjen, Many thanks for your prompt reply. 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 Actually, I have tried this also (I should have mentioned this in my previous posting). Moreover, I have set permissions to USB devices to make them accessible for the uucp user, so I hope the permissions should be ok. [r...@substance /usr/local/libexec/nut]# ./usbhid-ups -u root -DD -a CyberPower Network UPS Tools - Generic HID driver 0.34 (2.4.1) USB communication driver 0.31 debug level is '2' upsdrv_initups... No appropriate HID device found No matching HID UPS found Could it be that FreeBSD recognizes my CyberPower device a little bit different than any Linux machine (say, the device signature as recognized by USB driver is different) - so a small patch of the nut source code may improve the situation? Can I debug nut or libusb further to see what is going on inside?
