legacy USB

[shitan]

Hey everyone,

I have a small question concerning legacy USB support. I remembered that when I first installed os x on my pc (it was 10.4.8, i think), I had to deactivate legacy USB in my bios (MB: Asus A8N32-Sli Deluxe) - i am not sure if it was so that USB devices were recognized in os x, or if it was so that USB2.0 worked. Something in that taste.

Now i realize I need legacy usb to boot from a usb stick, which is something i'd like to do from time to time (i have a ubuntu pendrive). Since 10.5.2 and all that, is it ok for me to reactivate legacy USB? or is it still a bad idea?
