class firmware_DevBootUSB(FAFTSequence):
Servo based Ctrl-U developer USB boot test.
This test requires a USB disk plugged-in, which contains a Chrome OS test
image (built by "build_image test"). On runtime, this test first switches
DUT to developer mode. When dev_boot_usb=0, pressing Ctrl-U on developer
screen should not boot the USB disk. When dev_boot_usb=1, pressing Ctrl-U
should boot the USB disk.
