The trick seems to be if the computer can recognize the Reader as a storage device (even without the Sony Connect/Library sw installed), it will charge. I haven't drained the 505 fully so I don't know if it would charge that way. (The 500 seems to require the Library sw in order to charge from a computer, as I recall. Not sure though.)

That is exactly my experience from this week. I had been charging from a USB to mini-USB cable connected to the laptop. No problems at all.
But I ran into a situation where I wanted to hook up both my Motorola Q phone and my PRS-505 at the same time to charge them. So I tried to use a AC wall wart to mini-USB that I use to charge my cell phone. Instead of charging, the PRS-505 went from half-full battery down to zero battery.
Charging the PRS-505 back up with the USB on my laptop proved to be slightly tricky. The first few attempts with the usual port and cable did not work. I had to move the cable to a different USB port before the light on the PRS-505 would light up and the device would begin charging.
So now I have (2) USB to mini-USB cables hooked up to the laptop. I may end up picking up a AC to PSP plug for use in situations where I don't have my laptop.
It's a shame that AC to mini-USB charging cables don't seem to work reliably. I'm pretty sure that the fault lies in the software on the PRS-505 and not the voltages / amperages put out by the AC to mini-USB wall wart.
