Comment 19 for bug 1589585

That no-open fix was specifically for the DFU endpoint wasn't it? So if something like that is what's needed for this scenario probably still needs to be put together.

Alright so I think there are a few more interesting data point that are needed here.
1) What's the kernel got to say about all these disconnects and reconnects? Can you share your dmesg from a boot with fwupd present and running.
If you've got some dying hardware, it's possible that fwupd is just behaving badly based upon what it's seeing.

2) It would also be interesting to see what it looks like when fwupd is not running. To see this move the auto start service out the way, power off, power on, share your dmesg, and put it back.
# sudo mv /etc/xdg/autostart/gnome-software-service.desktop ~
# sudo poweroff
<turn on machine>
<check dmesg>
# sudo mv ~/gnome-software-service.desktop /etc/xdg/autostart

3) Check and see if you can turn off your finger print reader in the BIOS. If you can, that should at least help with this problem for now until we can figure out what's really going on.
