what are the power specs on the data pins for a usb port? Answered

i am wondering if i can integrate the usb ports to control an outside circuit, so basically, is the data pins on a usb port pull high or low enough to trigger standerd AOI logic gates? Then, if im not asking too much, could someone upload a simple program, (any language but has to work on windows 7) that trips the output, turning it on and off? also, is it bad or will it slow down my computer if i send a constant data packet to the usb?

Just use an FTDI serial port.
