mouse WM311 does not work

Hello,

I bought a XPS L502X with a WM311 mouse. When I connect the nano connector to the laptop it recognize it but the cursor is not managed by it. I try connecting the nano to each usb ports and also tried on an old Inspiron E1505 with the same result.

I check the usb ports of my new laptop with a wired mouse and both ports worked perfectly so I can say that the problem is on the mouse.

I found several post about pairing the mouse with the receptor but there is no button on either parts to re-sync them so I have no idea to troubleshoot this.

I´ll really appreciate any suggestion :)

Thanks,
