What I don't see here is new input device created. As I don't have USB mouse around me to test, will you connect your another mouse and check in dmesg log if there is line similar to

[ xxxx.xxxxxx] input: Logitech mouse as /class/input/inputN

If there is such line for Logitech wireless there I would propose to ask on h-e-n thread, maybe usbhid does not support your A4Tech mouse

also may I have your /tmp/Xorg.0.log
