Talking to a motor driver through USB

Question

I have a motor, connected to a motor driver, connected a windows XP computer by a CAN-BUS (throught USB). I want to "talk" to the motor driver and have some questions:

• Does the USB appear as a COM port?
• What protocol do I use or how do I find out what protocol to use?
• Does anyone have or know of any public implementations of a similar thing that I can look at?

• Are there any other hits you want to share?

  Thanks!

While I also think SO is a better place for this, I do have some useful information.

Check out this CodeProject article, it explains the basics of talking to USB devices, with a sample Win32 application. It's pretty focused on the HID class of USB devices, so if you CAN based driver doesn't present itself as a HID device, you might be in for some pretty significant work.
