The usb_template module implements various USB templates that are needed when programming an USB device side driver. A USB template consists of an USB device descriptor, one or more USB configuration descriptors, one or more USB interface descriptors, one or more USB end‐ point descriptors, USB strings and additional USB descriptors. USB templates are selected using the hw.usb.template sysctl and tunable. The hw.usb.template value can be changed at any time, but will not have any effect until the USB device has been re-enumerated. Avail‐ able templates are: Value Description 0 USB Mass Storage 1 CDC Ethernet 2 Media Transfer Protocol (MTP) 3 USB serial port 4 USB audio 5 USB keyboard 6 USB mouse 7 USB phone 8 CDC Ethernet and serial port 9 USB MIDI
