Using USB to drive a machine contains many problems.
The machine controll engineers understand that it's getting harder to buy a computer with a parallel port, and are working on making this work in USB in the distant future.
The controller software needs to send movement signals to the cnc drivers at precise timing intervals.
USB prohibits that, as it contains its own timing information. But it's very easy with a parallel port.
Your computer is basically a parallel device.
You can buy a parallel port card to plug into one of the expansion slots inside your computer for about $30 US. If you've already got the PC, you need to take a picture of the inside of the computer, showing the expansion slots.
Keep in mind that for $30 you can frequently buy an older computer which already contains a parallel port. For this type of work, older computers often work better.
