I'm the person in charge of allocating the usb minor numbers right now. If you will post your driver, and why you think you need a minor number, I (and the mailing list) can review and discuss it. > Also, I understood that there is a way to communicate with the kernel driver > from a user mode application without using the mknod command to create the > link to the driver.

Your driver can create a /proc entry that userspace can use to talk to your driver. Or it can export a filesystem (like the pci hotplug driver does) and have userspace programs interact with the driver through it.
