Drop the counter, it has no meaning other than being the order in which the interface is found; the name assigned to the USB host controller interface is a better indicator.
Example of the original output:
USB0: USB EHCI 1.10 scanning bus 0 for devices... 2 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found
Patched output:
Bus usb@ee080100: USB EHCI 1.10 scanning bus 0 for devices... 2 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found

Notes: Changes since v2: - Dropped counter altogether.
Changes since v1: - Improved commit message.
