usb_register_driver - register a USB interface driver

• int usb_register_driver(usb_driver *new_driver, module *owner, char *mod_name)

@new_driver: USB operations for the interface driver
@owner: module owner of this driver.
@mod_name: module name string

Registers a USB interface driver with the USB core.  The list of
unattached interfaces will be rescanned whenever a new driver is
added, allowing the new driver to attach to any recognized interfaces.

Return: A negative error code on failure and 0 on success.

NOTE: if you want your driver to use the USB major number, you must call
usb_register_dev() to enable that functionality.  This function no longer
takes care of that.
