I have been wondering, if there is a way to control the power output of a usb port. is there an api or dll. I have two fans that are powered through a usb port, and I kinda want to play around with them.

The voltage on a port is controlled through the device driver for the device plugged in.

(without a driver) it defaults to 100ma, and it maxes out at 500ma.
