Clutch GM60 lights turns on when PC is turned off

[farrainbow]

I have Clutch GM60 mouse and encounter disturbing behavior.

After PC shutdown lights on mouse goes off as expected - but if anybody touch any button on mouse then lights immediately turns on and stays on forever (no expiration timer). So PC is still off but bright illumination shines. Only way to turn lights off again is to disconnect PC from mains.

My PC is also MSI (Nightblade MI2), I have latest BIOS (EB090IMS.856), have searched all BIOS settings (very few ever exists on this model) - no luck. Firmware of GM60 is 24 and Gaming Center (1.0.0.52) doesn't offer anything newer.

Have anybody encounters such behavior? Any ideas how to keep lights of mouse off permanently when PC is off?

Thanks in advance for your thoughts

Which port is the mouse connected to?
Is it possible it's one of the ports that is always active even after the PC is turned off?

All other peripheral before looks for me normal - shuts down with PC. Nevertheless have tried to connect mouse to different ports (all 7 from 8 available - 5 SS and 2 regular, 1 SS has small connector and could not be used for mouse), no luck.

In MB BIOS I have only two lines related to Power Management  (see screenshots attached), tried already all possible combinations. Also in Gaming Center(x64) (v.1.68) option for USB Supercharge exists, tried it to on/off also to no effect.

Any ideas how to check - is it MB or mouse problem?
