Why don’t you like USB ?
- macleginn 5y agoUSB controllers are usually unable to provide more than 6-key rollover. Some keyboards offer two parallel cables for 12-key RO, but for real NKRO you basically need PS/2.
- kstrauser 5y agoI wouldn't say "usually" anymore. I was just able to mash 18 keys at once on my non-exotic keyboard and have them independently register. NKRO over USB isn't that rare now.
- open-paren 5y agoMaybe that was the case in the past, but I don't think that's true anymore. Using this[0] page, it will register as many keys as I can mash without triggering a global hotkey. [0]: http://gadzikowski.com/nkeyrollover.html http://gadzikowski.com/nkeyrollover.html

- fsflover 5y agoOn Qubes OS, USB devices are isolated from the system to prevent BadUSB attacks. This makes using a USB keyboard quite complicated and less secure: https://www.qubes-os.org/doc/device-handling-security/#usb-security https://www.qubes-os.org/doc/device-handling-security/#usb-s....
- stonewareslord 5y agoDo you have a mechanical ps2 keyboard you recommend? Also what do you think of USB->PS2 converters?
