usbutil monitor --events attach,detach,reset Now outputs JSON or plain-text logs whenever a device is plugged or unplugged. This eliminates the need for polling loops in scripts. Version 102 introduces a pluggable quirk system. For problematic devices (e.g., certain FTDI adapters that require a reset after enumeration), you can now define rules in /etc/usbutil/quirks.d/ . An example quirk entry:
usbutil reset /dev/bus/usb/003/007 The reset command sends a USB port reset signaling, re-enumerating the device. Create a udev-like script using the monitor: usbutil ver 102 new
This article explores everything you need to know about this update: its features, installation, command-line enhancements, bug fixes, and why version 102 marks a significant milestone over its predecessors. Before dissecting the "new" in usbutil ver 102 , it is crucial to understand its origin. usbutil is a lightweight utility suite designed to enumerate, configure, and debug USB devices from the terminal. Unlike graphical tools (e.g., lsusb -based GUIs), usbutil focuses on raw speed and scriptability. For problematic devices (e
In the world of low-level system utilities, few tools have maintained relevance across decades of operating system evolution quite like the usbutil family. For IT professionals, embedded systems engineers, and power users, managing USB devices at the kernel level is not just a convenience—it is a necessity. The latest iteration, usbutil ver 102 new , has recently surfaced in development circles, and it promises to redefine how we interact with USB stacks on legacy and modern Unix-like systems. Before dissecting the "new" in usbutil ver 102
usbutil list --json | jq '.[] | select(.speed == "super-speed")' Depending on your OS, the installation method varies. Note that many stable repositories still ship version 101 or older. To get the new v102, follow these steps. On Ubuntu/Debian (from source) sudo apt remove usbutil # Remove old version sudo apt install build-essential libusb-1.0-0-dev git git clone https://git.savannah.gnu.org/git/usbutil.git cd usbutil git checkout v102-new ./configure --prefix=/usr make sudo make install On FreeBSD (using ports) cd /usr/ports/sysutils/usbutil make deinstall make clean make install # Ports maintainers have updated to 102 as of Q2 2025 On Windows (via WSL or Cygwin) For Windows users, usbutil ver 102 new is not native but runs flawlessly under WSL2 with USB/IP passthrough. Install WSL Ubuntu, then follow the source compilation steps above. Command Examples: Harnessing the New Features Let’s walk through practical use cases that demonstrate the power of this release. Case 1: Identifying a Misbehaving USB Drive usbutil list --verbose --json | jq '.[] | select(.product | contains("Flash"))' Output includes device path, current power state, and error counters (new in v102). Case 2: Resetting a Stalled Device Without Rebooting Previously, you needed to unplug physically. Now:
vendor=0x0403 product=0x6001 reset_on_attach=true Through internal refactoring—removing deprecated libusb 0.1 calls in favor of libusb 1.0.26+—the new version consumes 18% less RAM when listing 50+ devices. The binary size has also dropped by 12% on x86_64. 5. --json Output for All Commands Parsing usbutil output in Python, Ruby, or Go is now trivial. Every command from list to tree to status supports:
