I got to this party late but thought it might be worthwhile to mention 
this.
I put a Canoscan LIDE 35 that has been collecting dust on an old P3 
machine and it "just worked".  I moved it in to this machine, where I 
really wanted it, and it "JUST BECAME VERY INTERMITTENT". No external 
hub, no root hub port seemed to make any difference -- until I bought an 
externally-powered hub to drive the scanner.  Shazam! It hasn't missed a 
beat since.
Obviously, the bus-supplied power from this m/b,p/s combination was 
marginal.
The m/b that worked 100% - ASUS P3V4X Rev 1.xx
Intermittent m/b - ASUS A7N8X Deluxe Ver 2
Both with commodity p/s mfg by Obscurename, Ltd.
