Bug Description

When you plug-in a rtl8188fu USB dongle it's not supported by default in Ubuntu.

When using https://github.com/kelebek333/rtl8188fu to add support, any time you plug the USB dongle everything freezes in Ubuntu, you can't longer use sudo.

Looks like systemd-udevd starts to hog the CPU at 100% until you disconnect the dongle and reboot the system
