Tried with: usbutils 1:012-2 and Ubuntu 20. Although the devices show up in /var/log/boot.msg they are not displayed with 'lsusb'.

To get incredibly verbose information, run with sudo: The output of lsusb on SUSE Linux Enterprise Server 10 and SUSE Linux Enterprise Server 11 on the same hardware is different and missing entries of sub-devices on SUSE Linux Enterprise Server 11.

The lsusb command provides information about the USB devices attached to your Linux system.

#Get lsusb install

Before getting started with the lsusb command, install the usbutils package onto your Linux.

ID 0bc2:2100 Seagate RSS LLC FreeAgent Go How to Use the LSUSB Command Install usbutils Package. ID 1d6b:0002 Linux Foundation 2.0 root hub But I was getting 'couldn't open serial port'. usually: ' apt-get install usbutils & airmon-ng' does the trick.

To view both the tree and device names: When I write lsusb -v I always get 'Couldn't open device, some information will be missing' Is this normal to get for each bus P.S: I was trying to read from a laser scanner which is connected via USB.

This shows the hierarchy with port, class and driver details, but the human-friendly device names are lost.

When I use the Detect feature in gnome-ppp, its says no modem was found.

But after upgrading to 9.10, gnome-ppp is unable to find the modem. It presents a human-friendly view of the output of the usb-devices tool, which also ships with usbutils. I have a hardware USB modem, the Best Data 56USB-SP/56USB-SPMAC/56USBP, that worked well under Ubuntu 9.04 and earlier. Lsusb is a handy utility to view the USB buses and devices connected to USB ports on the computer.
