I noticed the "can't open device" at the top of the listing before, but I also saw that every other entry in the results from "lsusb -vvv" (including the mouse) had the same string, so I didn't think it was unusual. I did notice that my USB stick didn't have that message. Unfortunately, I don't recall much about the git pull, except when you told me how to do it however many months back it was. I pulled it and then went on my merry way modifying it. Is there some way to look in the code/data to see it? Either way, I haven't changed/updated the code since that pull, so if you made the change after that, it hasn't affect me at all. And if you made it before the pull, then I've still been able to successfully use the shutdown command with this code just a few months ago, and today using Porteus.

Usually I'd say run that as root when the driver isn't running, but I'm looking for the device descriptor, which should be available regardless. The version number of your driver says "2.7.2.6_RTD". Which Git revision does that correspond to in the NUT repository (aside from your changes)? I'm curious because somewhere (af5f84c5) between 2.7.2 and 2.7.3, I removed a spurious usb_set_altinterface() call, and I'm wondering if that changes the claim/detach error messages. -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
