Scanner worked in 15.10 does not work in 16.04

I think it could be a problem with power save for some usb-devices.
With my Canon Lide 25 i had the same problem.

This solution works for me:
Go to the file tlp. Path /etc/default/tlp . You need to have writing rights.
You will find the line USB_BLACKLIST=
Search for it. Here it’s line 178.

Here i wrote the USB-ID after USB_BLACKLIST. Then remove the #-sign.
Like this:

The USB-ID you will get with lsusb in terminal.

Save the file and re-plugin your scanner. Perhaps it’s working now.
