M90 unresponsive, but lights flashing after firmware update


Recommended Posts

Got a new m90, used it for a couple of days, then firgured I should update the firmware.

After the firmwareupdate completed, the lights (logo and inside the mouse too) started flickering randomly, and the mouse was unresponsive.

I plugged the mouse out of the usb port, and then plugged it back in.

No reaction from the pc, no reaction from the mouse. This hasn't changed since.

I did find out however, by pressing button 7 (according to the management-tool) the lights in the mouse start blinking on and off every second.


If anyone knows what to do, any help would be greatly appreciated!


I have had no luck so far with google.
