That's not possible.  All HID devices (mice and keyboards) feed into the
system's central input process.  They will all affect the cursor.  Think
about it for a moment -- how would you tell the system which mouse
device you wanted?

Theoretically, you could replace the system's mouse driver with one of
your own using something like libusb, but that's a heck of a lot of
work.  You'd have to understand how USB requests work, and how the USB
Human Interface Device Class works.
