I have a 40PFL660H/12 television with software version Q551-0.14.93.0. I have connected a Rapoo E2700 (http://rapoo.com/showdetails.aspx?P_No=E2700) wireless keyboard with built-in touchpad to the television.
The television comes up with the message "USB mouse connected" and I see the mouse cursor on the screen.
However noting happens when I use the touchpad, the cursor remains stationary. The keyboard function of the Rapoo E2700 works fine.
The touchpad works fine when I connect the Rapoo E2700 to my computer.

Has anyone an idea why the television doesn't work with this keyboard/touchpad?
