I notice that, after booting from my Live USB (with Ubuntu inside) and shutdown, I won't be able to boot it again, unless I unplug the USB and plug it in again.

Is this a side-effect of something, or is it intentional? I wonder what mechanism is used to do this?

I wouldn't say it is intentional and I'd suspect BIOS or internals of motherboard. –  Maciej Piechotka Oct 4 '10 at 21:08
    
but at least there must be some way the computer made physical changes to the USB, because I don't think the BIOS can keep any data once the computer is shutdown? –  phunehehe Oct 5 '10 at 9:02

This is probably caused by some peculiarity of your BIOS. Definitely not intentional.

hmm now I believe so... I tried on another machine and it wasn't "locked" –  phunehehe Oct 24 '10 at 7:01
