Hi, here is my complete solution on how to forward a USB port to WSL2, using the latest usbipd-win. Note that my use-case is connecting to an rplidar fromSlamtec, which uses a Silicon Labs CP210x USB-to-serial Interface board to connect to the actual Lidar device. ACTIVATING USB FORWARDING TO WSL2 Purpose: make USB to Serial Bridge accessible in WSL2 to test the RPLidar SDK build on WSL Linux (Ubuntu)

1. Install usbipd-win on the Windows-host: https://github.com/dorssel/usbipd-win/releases
2. Install USBIP tools and hardware-database in Linux (WSL) bernd@myOmen:~$ sudo apt install linux-tools-generic hwdata

--- getopt(3)-like functionality for Lua 5.1 and later
-- This is free and unencumbered software released into the public domain.

--- getopt(argv, optstring [, nonoptions])
--
-- Returns a closure suitable for "for ... in" loops. On each call the
-- closure returns the next (option, optarg). For unknown options, it
-- returns ('?', option). When a required optarg is missing, it returns
-- (':', option). It's reasonable to continue parsing after errors.
-- Returns nil when done.
