I bought a Lexar Triton USB 3.0 thumb drive for my rMBP and tried to boot from it with no luck. The computer basically freezes on the boot and nothing happens. If I boot with option pressed and then plug the thumb drive, same thing happens. The EFI boot screen freezes.

Booting off USB 3.0 thumb drive not supported?

I have booted a 2011 MBP off of a USB 3.0 drive (using USB 2) before just fine. It could potentially be the rMBP misbehaving, though.
Well, I can boot the rMBP using a USB 2.0 drive as well, but I haven't tried if I can boot another USB 2.0 mac using a USB 3.0 drive though, I'll test it.

It appears the rMBP doesn't like certain USB thumb drives for booting. I can reproduce this issue all day long on a Corsair GT USB 3.0 16 GB.
However, it does seem to work with my Corsair USB3.0 32 GB, so I know it's not the method that I'm using to make the thumb drive.

I built a bootable Mt. Lion drive on an old Transcend 2.0 Flash drive I had around. It worked just fine.
Thinking a 3.0 drive would be better, I bought a new Transcend 8GB JetFlash700 Super Speed USB 3.0. It works just fine too.
The extra speed of the 3.0 didn't really seem to make much difference. A 2.0 Flash drive is probably more than sufficient even for an installation.

I have gotten the no smoking sign a few times trying to do a clean install, sometimes I randomly don't. Not sure why.
