; LectroTIC-4 USB serial driver INF
; -----------------------------------------------------------------------------
; Maps USB VID 0x1209 / PID 0x71C4 (Lectrobox / LectroTIC-4) to Windows's
; built-in usbser.sys CDC ACM driver. No third-party driver code is shipped
; here -- this file just tells pre-Windows-10-1607 Windows which built-in
; driver to bind to the device. Windows 10 1607 (August 2016) and later
; load usbser.sys automatically for any CDC ACM device and don't need an
; INF.
