If you want to make things harder for you and your users, sure, you can. But your driver will not be accepted into the main kernel source tree unless you have a very good reason why it can not use that core. Also, you will have to get a new major number assigned, which is pretty foolish as you should be using the usb-serial major number instead.
That was interesting Greg :). Thanks a lot for the information. Will use usb serial core for the driver. Thank you
good luck, greg k-h
