Problems with USB mouse on 12.04 LTS

  • 772

My mouse stops working after a few seconds, or a few minutes at most. It works fine on my Raspberry Pi and on my Mac, but my Ubuntu 12.04 LTS system complains:

[  654.508063] usb 2-5: new low-speed USB device number 4 using ohci_hcd
[  654.712876] usb 2-5: device descriptor read/all, error -71

When I unplug and re-plug the mouse, it will work for some more seconds. This is obviously not a solution. Any ideas?

  1. It might be a problem with the USB suspend power-saving feature.

    If you have powernap installed, this might help:

    sudo powernap-action --disable usb_autosuspend

    Without powernap, you could try disabling the autosuspend feature in the usbcore module:

    echo "options usbcore autosuspend=0" | sudo tee /etc/modprobe.d/usbcore

    You'll probably have to reboot (or unload and re-load the module, but good luck with that if you're using a USB keyboard) to see if the change is effective.

    If it doesn't help, do the following to clean up:

    sudo rm /etc/modprobe.d/usbcore
