Firmware update on M90 and it stopped working

Hey

im currently using the Corsair M90 mouse and when i where to update the firmware it just stopped working, there are only 2 LEDs on the side that is ligth up now too, the top one and bottom one.

Button that is currently working. Mouse 1,2,3 no other buttons than those works for me anymore.

I tried to reflash the firmware but now it only says "Cannot open USB device, please plug the device into a USB port or reinstall driver"

Thanks for your time and help

attached a picture of the mouse if that is to any help

Can you try it on another computer and see if you can reflash the M90?

Have you tried reinstalling the firmware updater?

If the firmware updater says the same error, Request an RMA to replace the mouse.

iv done both of those things, thanks for taking you time to answere tho! :D

and what is this RMA thing?

I received today my M90 Mouse an I have the same Problem like @noren1.

Up and down Lamp is on and the Firmware Updater don't find the mouse anymore.

I think, because the mouse is not using the CORSGMS.sys driver anymore and I have no Idea how to force Windows to do so.

Also on a other Computer it don't work.

What can I do? I am in Brazil.

UPDATE:

I could force Windows to use the CORSGMS.sys driver and after that I could make successfully the Firmware update.

Everything is ok now, but I am a older Person and You almost gave me an Heart attack.
