usfull info for usb charging

[Dale.s]

For a while ive been wondering how to get the 500ma+ out of usb since most only supply 100ma without a device "asking" for more. then i found this page.. USB - Universal Serial Bus Connector Pinout - AllPinouts

The interesting bit is at the bottom of the page...

USB Charger

To force charging of your iPod, PSP or any USB device, you have to force high the levels of the data pins 2 (D-) and 3 (D+) by connecting them to a +5V using a 10KOhm resistor.

Thought sombody might get use out of that little bit of info.
