See if you can get a linux driver.

First I did a DDG search for  "Logitech M570 linux driver"    and got

See if you can get anything from

http://support.logitech.com/en_us/produc...kball-m570

I also noted

It says it supports chrome OS.  Chrome OS is a stripped down linux distro.  Stuffs that work on Chrome OS should work on LL.
