My wired keyboard randomly stopped working on my Raspberry Pi 3 after working fine for two weeks. My wired mouse still works fine.

I've tried swapping both into all 4 ports and the mouse works in all of them and the keyboard in none of them. The keyboard still works fine when I plug it into my mac. All other functionality on my Pi seems to work fine except the keyboard.

  • The next thing to check is another keyboard. It could be an USB power problem. Plug in a powered hub, and connect the keyboard to the hub.

  • Ok borrowed a friends keyboard to test and their keyboard works on my Pi but I will need to return the keyboard soon. I'm still hoping to troubleshoot the issue with the initial keyboard (it should work since it works on my mac)

    It could still be a power problem. Also, a mac keyboard has an internal hub if I remember correctly. Is some power-hungry device plugged in there? A bluetooth or wifi adapter maybe?

  • No bluetooth or wifi adapter. I do have a wired mouse, a monitor plugged in, ethernet plugged in, and a pi camera connected. I was using an "Insignia" wired keyboard and switched to an "HP" wired keyboard which now works. It seems weird that it would be a power issue since my set up has been working fine for a couple weeks now and I didn't change anything.

The keyboard was drawing too much power. I replaced it with another keyboard and now it all works fine.
