USB Mouse sleeping after 5 seconds when on battery [duplicate]

To solve this problem on 12.04 and continue using laptop-mode-tools edit the file:

/etc/laptop-mode/conf.d/usb-autosuspend.conf

$ sudo gedit /etc/laptop-mode/conf.d/usb-autosuspend.conf

And look for the line:

AUTOSUSPEND_USBTYPE_BLACKLIST=""

Replace with:

AUTOSUSPEND_USBTYPE_BLACKLIST="usbhid usb-storage"

This will automatically disable USB autosuspend if you have ANY mouse and even USB drives plugged in.

I had the same problem, I think after I installed either laptop-mode-tools or powertop. Instead of uninstalling them again...

• enter sudo powertop in a terminal
• use the right arrow key to change to the tab Tunables
• use the down arrow key to select the line with Autosuspend for your USB mouse
• press Enter to toggle this line to Bad
• quit powertop with the key q

EDIT: Too bad, this is just a temporary solution. It does not survive a reboot...

However, I found something else. If you have laptop-mode-tools installed, try to set CONTROL_USB_AUTOSUSPEND=0 in the file /etc/laptop-mode/conf.d/usb-autosuspend.conf

EDIT: setting BATT_SUSPEND_USB=0 should also solve the problem (at least it solved mine).
