NAME
       usb_get_dev - increments the reference count of the usb device structure

SYNOPSIS
       struct usb_device * usb_get_dev(struct usb_device * dev);

ARGUMENTS
       dev
           the device being referenced

DESCRIPTION
       Each live reference to a device should be refcounted.

       Drivers for USB interfaces should normally record such references in their probe methods,
       when they bind to an interface, and release them by calling usb_put_dev, in their
       disconnect methods.

RETURN
       A pointer to the device with the incremented reference counter.
