I have the Level 1 KVM (1.4 Display Port KVM Switch Single Monitor, 4 Computer) and have been running into a weird issue.
I am using an IBM Model M keyboard with an SDL to USB cable. Been using it fine for the last decade or so. When I plug it into the L1KVM HID port, every time I press a letter it spams the button down. If I plug into a non HID port, everything works fine. Has this ever been seen before, and is there a remedy I can try?
