Hi Peter,

To answer your question, yes you can use USB2 to boot your MacBookPro. I have a 
USB 2 'cheap' drive here which I book my MacBook from and although a little bit 
slow it nonetheless works fine. 

Please refer to Apple's article at:

http://support.apple.com/kb/HT1948

Bear in mind though that USB 2 does not support 'Target Mode', at least that is 
my understanding. 

Kind regards,
Philippe
