So this might be an electrical issue with your keyboard, > the USB connector it is plugged into, any USB hubs or cables along the > way, or anything like that. the same cabling as before, plugged into USB2.0 or USB3.1 ports doesn't make any change, booting USB legacy modes, no change, booting system in bios mode, no change, PS2 emulation no change. the cable is not being moved at all at times and the problem still happens. hubs and devices found seem common and i'm not having any issues with any other USB devices. i did look around on the web to see if others were having troubles with this keyboard and motherboard and didn't find any. it's not a very old keyboard, but old enough that i'm pretty sure it's past any burn-in period where i'd suspect the electronics. me@ant(1)~$ lsusb Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 174c:3074 ASMedia Technology Inc.
