Comment 209 for bug 88746

I've now tried putting the autosuspend into the boot procedure....
After power-on this works succesfully.
There may still be problems after a restart.

My procedure was as follows:

1. Type the following in a terminal window:
         sudo gedit /etc/modprobe.d/usb-core-options
2. Add the following line to the usb-core-options file:
        options usbcore autosuspend=-1
3. Save your changes, and then type the following in a terminal window:
      sudo update-initramfs -u
4. Shutdown and power on your computer. (Don't use the restart option)
