In a sense..... you can make a completely vendor-defined device and talk to it via libusb or winusb.

In the latter case you'll also want the special Microsoft descriptor for silent installation of the winusb driver

"Class" in USB context usually means one of the already defined classes, usually with native support in major OS.

But yes, the OP can use the "Vendor-specific" class code (0xFF); and also he/she can present a powerful enough organization to suggest and establish its own class within USB's standards framework, and persuade the major OS vendors (and yes, Linuxen do have their vendors) to write, integrate and disseminate the respective drivers.
