We plugged one of the Xbox 360 play-and-charge controllers into our late-model IBM laptop. Windows didn't recognize the device, and Windows Update didn't either, but this is to be expected as only the wired controller works on PCs.
However, if you're out of USB ports on your 360 and still have some controllers you want to charge, you can use any powered USB port to charge 'em up. That's what biologists call a parasitic relationship. The host gets nothing out of it, the parasite sucks a little juice out of the host. It'd be nice if the wireless controllers wree able to use the wired connection to the host PC to function just as the wired controllers do. It's cool. Just experimenting!
