Advanced USB delay handling
USB boot delay is now handled with the usbdelay kernel param (default=0) We use the built in delay of usb-storage to control this. by setting the module's delay param. If your USB device doesn't work on first boot, try setting usbdelay=10 or so Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
