Sorry, I'm not very familiar with how the usb protocol works- but I meant, that not all OS-provided keyboard drivers support devices with up to 100-whatever simultaneous keypresses, right? I've seen keyboards with what looked like hardware 'nkro' toggles, and overheard discussions to the effect that many implementations of nkro over usb are sometimes 'unreliable', which sounds like inexcusable behavior on either part of the keyboard's controller, the software driver, or the protocol itself.
