I've just discovered that none of my USB ports appear to be functioning correctly on my Lubuntu install. lsusb shows I have the following:

Bus 002 Device 002: ID 03f0:171d Hewlett-Packard Bluetooth 2.0 Interface [Broadcom BCM2045]
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So far the only thing I appear to have gotten to detect and work correctly is a usb mouse (below) and my phone will charge (but not be detected) when plugged in.

Bus 002 Device 003: ID 0461:4d64 Primax Electronics, Ltd

Three USB memory sticks I have to hand and a printer I was trying to install don't appear to be detected at all.

Does anyone have any pointers I can try?


You can give a try to this:

  • Install dconf-editor

    sudo apt-get install dconf-tools
  • When installed open it using following command and follow mentioned path:

  • Path: org->gnome->desktop->media-handling and check automount and automount-open

  • Sometime it detects but doesn't mount, so execute following command and see what happens:

    sudo mount -a

    sudo mount displays all the media that is mounted in your system..

  • If it does not work then try to open your system in another shell like gnome-classic or gnome-class(no effects) from login screen and check what happens.

Hope it somewhat helps you!!
