Unless the battery monitor is wrong, I'm pulling between 900 and 905mA from my desktop computer's USB 2.0 port... which is the same current I pull from my Mogul's wall charger.
I remember it used to be next to impossible to charge an HTC from USB!
EDIT: Just so everyone knows, I didn't realize that its coming from the fact I'm running mightmike's AWESOME MightROM
