I'ts been at least a decade since I did this, but I recall aomething
called rEFInd I had to install to help the process.
There is also a boot option to hold another key to specify which
alternate storeage device you wanted to boot. c was CD - the only
device I used. Maybe u will get you to your USB.
My other suggestion: is there a boot flag on the USB somewhere, perhaps
the efi partition?
