[Q] Charging at only 100mA from PC USB 2.0 port topic

Anyone know a fix for this so that it can actually use the full 500mA the ports can supply?

My S3 charges just fine at 500mA when I hook it up.

All I get from Samsung is "use supplied charger" :( Can't do that at my computer desk. No outlet close enough for it.
A 500mA charge would be enough to at least give it some power.
