19This test requires a USB disk plugged-in, which contains a Chrome OS test

21DUT to developer mode. When dev_boot_usb=0, pressing Ctrl-U on developer
22screen should not boot the USB disk. When dev_boot_usb=1, pressing Ctrl-U
23should boot the USB disk. It will then continually install chromeos while
24monitoring dmesg for errors.
