I have G510 keyboard and G700 mouse and problem with Z77 FTW motherboard.
It's not only Z77 FTW, many peoples with others ASrock, GIGABYTE and other motherboards ... have identical problem like me, We can't go in BIOS or use G510 and maybe G19 and maybe some other keyboards.
Keyboard is dead until desktop. Where is problem and who plan to help us to resolve that.
For now only options I see is cross to Steelseries. This is last options for because I use G510 over year and I am very satisfied.
But this things are inadmissible for this top gaming HW.
Who resolve problem and how???
I try with and without aoftwares with keyboard.
Any sugestions, advice...
G510 is one of keyboards with little problems and I choose because of that like G700, but this is big issue now.
