Comment 7 for bug 1483615

Hi Charles,

I can see your thinking, but no, this isn't a VM, nor is the kernel I'm using a Hypervisor - it's a plain old machine:

root@barnbox:~# grep -i hyper /proc/cpuinfo
root@barnbox:~#

I updated the machine with apt-get (again) and I also updated the machine's BIOS. Prior to doing the updates I tried the lsusb command and it worked:

root@barnbox:~# lsusb -vvv -d051d:

However, weirdly, since doing the update, usbhid-ups no longer segfaults - it still doesn't work, but it's interesting

Annoyingly, I never ran the intermediate stages, so I don't know which change made the difference (I suppose it could be HP's firmware doing something funky, but I doubt it...):

I believe this usbhid-ups command should match the UPS, but it appears to skip it:

Still, at least it doesn't segfault!
