On the mouse, there is a name, such as GMX-1
When plug into USB, there is no connection
Google and find an USB driver, install and it works.
But another laptop, without installing that USB driver (.exe file), this mouse work
So it all depend on the laptop.
Btw, both laptops are using Windows 7 Pro 64 bit.
Laptop = Toshiba -> unable to detect; Sony is able to detect, without driver or .exe file.
So, this do happened.
Google and search for the driver or .exe file to activate the mouse.
