Kobo breaking my usb ports

:blink: :angry: :help: :angry: :blink:

Not again!!! This was fixed quite a few releases ago (I think 4.4.9344 or something like that), and now the issue is back in 4.7.10413.

On all my linux computers, after I unplug/plug my kobo more than 2 or 3 times, or write/read more than about 300mb (it varies), the usb port stops working (with all devices) until a reboot. I can use a different usb port, and it works another 2 or 3 times.

dmesg shows the following interesting lines on the 2nd or 3rd connection:



I am at a loss for explaining this issue. I have tried downgrading and upgrading the kernel, changing kobo sd cards, trying different usb cables, trying another kobo (it's an aura ed2), and a whole lot of other things. I am using Arch Linux, Xubuntu 17.10, Debian Sid, and Fedora 27.

Note: no, the sd card in the kobo is not failing.
