Public bug reported:

I have a Toshiba L855 laptop at home. When I connect any usb device to a
USB3 port before boot then no other USB device doesn't work and even
detected after boot. This concern even USB mouse and keyboard. But when
I reconnect all USB devices to laptop then they started to work. I see
this behaviour on every ubuntu 16.04.5 linux kernel i.e. version 4.15,
so I suspect that it is due to some linux-extra-module. I have also
windows 7 OS on the same laptop and I have never struck such a problem
there.
