Have you checked if the mouse is showing in PCLinuxOS Control Center? Have you tried a different kernel? A different USB port?
Could you try uninstalling x11-driver-input-synaptics? Maybe a conflict there?
The mouse doesn't show in PCC.
Tried kernel 2.6.38 but the computer freezes with that kernel. Tried another distro with kernel 3.5.0 and the mouse wasn't detected.
I have two USB2 ports and one USB3 port. It didn't work in any of them however if I plug it into the USB3 port and do a power off restart it then works and will continue working if I move it to a USB2 port! If I just do a restart without a physical power off it doesn't work

synaptics driver has no effect.
