モダンなlsusbのようなcymeを少し試す

matoken bookworm・Debian・Linux

rust製のモダンなlsusb的なcymeというものを見かけたので少し試してみました．
cymeはlsusbとも互換性が有り，Linux/Windows/macOSで動作するようです．

install
$ sudo apt install cargo libudev-dev
$ cargo install cyme
$ export PATH=/home/matoken/.cargo/bin:$PATH
help
$ cyme -h

  1. 文字列でフィルタ
  2. hid class でフィルタ……うまくいかない?
  3. serialの一部でフィルタ
  4. vid/pidでフィルタ
よく使う sudo lsusb -d 17ef:6047 -vvv の代わり?

uninstall
$ cargo uninstall cyme
    Removing /home/matoken/.cargo/bin/cyme

lsusbでそう困っていませんが，cymeはlsusbと互換性があるし見た目も今どきな感じなので良さそうです．ただ自分で入れてまで使うかというと微妙．ディストリビューションパッケージに入ったら使うかもという感じでしょうか．

環境
$ cyme --version
cyme 1.2.1
$ dpkg-query -W cargo libudev-dev
