💖 lsusb(8) 💖 Linux USB Utilities ✨

🎀 NAME

lsusb - list USB devices

🦋 SYNOPSIS

lsusb [ options ]

💅 DESCRIPTION

okay so lsusb is the utility you use to look at the USB buses in your system and all the devices plugged into them 🔌✨ it's giving detective energy. It uses udev's hardware database to match the vendor ID and the product ID to a full human-readable name, so you get actual names instead of just random hex 🙈

🌸 OPTIONS

• -v, --verbose — main character mode 💅 tells lsusb to be verbose and show detailed info about each device. This includes the configuration descriptors for the device's current speed. Class descriptors get shown too, when they're available, for USB device classes like hub, audio, HID, communications, and chipcard. You can use it with the -t option 🫶
• -s [[bus]:][devnum] — only show devices on a specific bus and/or devnum. Both IDs are in decimal, and you can skip either one 🍓
• -d [vendor]:[product] — only show devices matching a specific vendor and product ID. Both IDs are in hexadecimal 🔥
• -D device — okay this one's a little different 👀 it skips scanning the /dev/bus/usb directory and only shows info about the device whose device file you give it. That file should look something like /dev/bus/usb/001/001. This option shows detailed info like -v does, and you must be root to use it 💀
• -t, --tree — dumps the physical USB device hierarchy as a tree 🌳 and you can crank up the verbosity by using -v twice 🧚
• -V, --version — prints the version info to standard output, then exits successfully ✨

🔮 RETURN VALUE

if the device you asked for isn't found, you get a non-zero exit code 😭
