PDA on USB: Don't need a driver, just want power! [SOLVED]

I have an o2 atom exec pda (one of those windows moble thingies). I haven't found how to integrate it with Linux at the moment, but that doesn't worry me too much (at the moment.)
What does worry me is that, I use to be able to recharge the device by simply plugging it into a USB port. Since upgrading Linux it has stopped charging. It's as though the power is turned off to the usb port.
lsusb gives me:
Bus 004 Device 008: ID 0408:f003 Quanta Computer, Inc.

Any ideas??

what kernel version?
do you have a powered usb hub to test the device one?

Kernel is: linux-2.6.21-suspend2-r5

When I reboot into XP (I dual boot for work reasons) it recharges. I'll test it on a standalone powered hub tonight (Aussie Time). Knowing that it use to charge when gentoo was running makes me think that someone has changed the usb power configurations.

That's it.

The device is trying to suck 500mA down the line. Thanks for the info. I'll just need to get myself a powered hub for work! Thanks iamben.
