hey guys, after searching around this seems to be an known issue with the c720 chromebook. Currently using linux mint, the link below says chrubuntu, but i am not using crouton. I have found a few pages that were like just create this script to fix it, but not much explaining what is happening.

I don't want to just copy and paste into my grub.cfg without at least knowing what the error means and what 'unbinding ehci' is actually doing.

AFAIK my usb ports work just fine, using a bluetooth mouse, so nothing is ever really plugged into them

Error 19 is (From /usr/include/asm-generic/errno-base.h)
if that throws any light on your problem. I found the ehci module to be a bit inclined to overreact. I had issues with it (back in the day when usb-2.0 was something to be excited about) previously but that was faulty Via usb ports. Via do that sort of thing occasionally. The eventual "FIX" was to take out some silicon and give 2 less usb ports.
