I am wondering if an application that allows a user to turn on/off individual usb ports with simple keystrokes exists. Example: user hits key x once to turn off usb port, and x again (or another key) to turn on said usb port. While all other ports remain on (or off depedning on original state). I assumed that since macs themselves can turn individual ports on and off, that an application would be able to as well. I thought this would be a relatively simple app, and that somebody would already have such developed (or something similiar) however i have been unable to find one as of yet.
