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.

I think that corresponds to this file:
http://lxr.free-electrons.com/source/drivers/usb/core/devio.c?v=3.16 (but I
don't see anything obvious there)
What does "lsusb -vvv -d 2a37:" return? 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.
