I might have done some stupid things while trying to install a network driver. Now when I run lsusb, it doesn't return any output. The command just keeps executing indefinitely. I can still kill it with CTRL-C or CTRL-Z. Is there a way I can fix this? If this indicates a more serious issue, how do I address that?

  • This can sometimes happen if a USB device is refusing to be queried for whatever reason. The first thing to do would be to disconnect all external USB devices from the machine and try lsusb again. If it continues to hang, then a driver for an internal device (such as a keyboard or touchpad) may be corrupted and in need of repair. System logs in /var/log/syslog may contain information relating to the issue.

  • Disconnecting devices didn't help, it appears to be a problem with an internal device

  • Cool. So you've narrowed it down to an internal device. This is progress. Does any log file show what might be causing the issue?

  • I tried to run the command again and checked the syslog file. It doesn't display anything after opening the terminal. I also checked other logfiles in the directory, but I couldn't spot anything meaningful

  • You had mentioned that this started after trying to install a network driver. Can you uninstall the driver? What does sudo lshw -C network reveal? If the network device is on the USB bus, it could be interfering with the rest of the system.

I solved the issue by uninstalling the broken network driver and rebooting.
