It uses networking devices, not char devices or block devices, hence no major/minor. A good reference (available on line) is the Linux Device Drivers book (2nd edition).
Perhaps you might like to explain exactly what you are trying to accomplish. There are lots of ioctl()s that you can use to do different things to the usb device (usbfs ioctls), the ethernet device (eg ethtool ioctls), the driver (private ioctl()s, if any), the networking stack, and so on. A good example of a user space tool for networking is the ethtool package from http://gkernel.sf.net. Another example, more complex, is the wireless tools package.
