You register with devfs. To do so you need a call like this:
usblp->devfs = devfs_register(usb_devfs_handle, name, ...
in your probe method.

It's not specific to USB. Look at documentation for character devices
to see a description.

Right.

There are two ways. Either you extract the minor from the inode which
you can take from struct file* you are passed using minor() and maintain
a table of minors.
Or you do this only on open() and store a pointer to the context in the
private_data field of struct file.
The second way is faster, the first makes it easier to write disconnect()
handlers.

Convinience and sharing a major number.
