firmware version 3822 -
the board doesn't recognize a "logitech illuminated" keyboard until windows is loading.
so no chance to do anything in the bios or prior to the windows boot.
i have to use another keyboard whenever i have to do such things.
maybe you can adress this in your next bios update.
Very likely this has to do with USB RMH mode, we are indeed looking into this and working on create BIOS/Driver solutions to this new Chipset Silicon USB mode. I replied about this same topic on this thread http://communities.intel.com/message/83305#83305
Hopefully, more to come soon.
