thanks bro, i appreciate your reply very very much... but i tried looking around at SS official website and couldnt find a specific page to download firmware? only can find the page to download the driver which is this http://steelseries.com/support/downloads
and of course i tried googling it but it keep redirecting me to this website above too... if you could be kind enough, can you actually lead me to the page to download this kana v2 firmware ?

thanks for the link to lyn steelseries thread.. will spend some time abit reading it on friday...thanks..

i did tried plugging in into different usb ports, in fact i tried all of them including 2 of my usb3 port, but none of them has different results. is ss engine 3 compatible with kana v2? i dont think so right ? i've tried experimenting, i uninstalling everything and unplug the kana v2, restart my pc and then i just install the ss engine without having my kana v2 plugged. after installing, it came out message saying 'driver not available. please check compatibility', this message will surely popup and i have to close it, and when i try to open the ss engine, no reaction at all... all this is done without the kana v2 plugged in into the computer

suspect its my computer or windows problem ?
