Corsair K68 not USB-HID standard compliant?

Recommended Posts

Hi all,


around two years ago, I replaced my trusty old Cherry G80-1000 (no Windows Keys :biggrin:) with a Corsair K68, to stay with the good old Cherry MX-Red that I like so much.


My main PC is a Xeon E5-2683v3 on an Asus X99E-WS and works perfectly in both, UEFI and Windows 10.


My legacy tool PC is a Core2Quad Q6600 on an Asus P5KR, which I would like to use with the same keyboard, using a USB Switch/Hub (2 Hosts switchable, 4 Devices). This PC will work perfectly with the K68 in Windows 7 and XP (Dual Boot), but not in the BIOS/Bootloader environment. Meaning to configure the BIOS or to select boot mode between 7 and XP, I need either a PS/2 keyboad or another USB Keyboard (a cheap Logitech wireless kit works perfectly also in BIOS/boot menu). This can't be it.


I arranged with this for some time, using for the time being the second keyboard on the Q6600, but in the meantime, as I am also deep into retro-computing (dreaming of a KVM switch to access anything from PC-XT to the Xeon), I looked for other solutions and started developing with an Arduino Mega 2560 with USB Input shield. So what shall I say? The Arduino can properly detects any USB Keyboard except the Corsair K68.


So what is wrong with this keyboard? Is there a firmware update? (found nothing on Corsair website) Any recommendation for other MX-Red keyboards that work as a proper USB-HID-Keyboard also with older computers?

Hi Dark_Lord,


The solution / answer here, is that all our keyboards have a baked-in "BIOS MODE" that will disable all software and firmware frills and RGB, and makes the keyboard work in a BIOS / UEFI environment.


For your K63, you simply need to unplug your keyboard, hold down B+L and plug the keyboard back in. That will enable the BIOS mode, which can be disabled with the same shortcut.
