Although it wouldn't be helpful for replacing the above described method when it were used on the PSP's serial Port I was thinking of a way I could do an internal mod on the PSP so it's USB port would be permanently powered. It's pretty obvious that Sony just rerouted the PSP's USB ports power from pin 1 and pin 4 to those two copper contacts beside its USB port as to prevent the use of non Sony peripherals with a Sony product in other words you're forced to buy their overpriced products. So I was thinking why not just bridge those contacts back to their original pins? At the very least you would have a portable usb power source and at most well who knows the skies the limit. BTW would this method also allow USB charging of the PSP or would the PSP USB Charger Mod still be requiered or perhaps the charger mod would conflict with this one.
