My 500 will not charge from an iBook. I have never had it charge from a PC without the proper drivers installed. I don't know why, but Sony choose not to load the USB port until it was sure it was a high-power port. It probably says somewhere in the USB spec that you're supposed to do some check. It's not a matter of the voltages being off, the problem (design feature?) is completely within the 500 electronics. I have other devices that give an error message "This port does not have enough power ..." if you plug them into a low-power port. There must be a way to tell. I also think that USB 2.0 ports are always high power, and I presume there is a way to check that as well. Several folks have reported that 505s charge from any USB power source, but I can't confirm that.
