A modern cross-platform `lsusb` that attempts to maintain compatibility with, but also add new features. Profiles system USB buses and the devices on those buses, including full device descriptors.\n\nAs a developer of embedded devices, I use a USB list tool on a frequent basis and developed this to cater to what I believe are the short comings of `lsusb`: verbose dump is mostly _too_ verbose, tree doesn\u0027t contain useful data on the whole, it barely works on non-Linux platforms and modern terminals support features that make glancing through the data easier.\n\nThe project started as a quick replacement for the barely working [lsusb script](https://github.com/jlhonora/lsusb) and a Rust project to keep me up to date! Like most fun projects, it quickly experienced feature creep as I developed it into a cross-platform replacement for `lsusb`. It started as a macOS `system_profiler` parser, evolved to include a \u0027libusb\u0027 based profiler for reading full device descriptors and now defaults to a pure Rust profiler using [nusb](https://github.com/kevinmehall/nusb).\n\nIt\u0027s not perfect as it started out as a Rust refresher but I had a lot of fun developing it and hope others will find it useful and can contribute. Reading around the [lsusb source code](https://github.com/gregkh/usbutils/blob/master/lsusb.c), USB-IF and general USB information was also a good knowledge builder.\n\nThe name comes from the technical term for the type of blossom on a Apple tree: [cyme](https://en.wikipedia.org/wiki/Inflorescence#Determinate_or_cymose) - it is Apple related and also looks like a USB device tree \ud83d\ude03\ud83c\udf38.\n\n![cli tree output](./doc/cli-tree.png)\n\n#",
