Keyboard and mouse and hub not working. I have acess via SSH and VNC though my laptop. The pi cannot see all that. I tried lsusb but nothing shows up except

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub`

I tried dmesg:

  • You have reached the limitation of these things the USB implementation leaves a lot to be desired is the polite way of putting it. If I plug my keyboard in it fails to boot most times. To say I am unimpressed is a mild understatement. Try plugging it in after boot that seems to work for me...

    It seems you've got a short on the USB ports. Try removing everything and start plugging in one device after the other. The device that first fails is probably broken.

Thanks @PMF. My keyboard was spamming data in the rpi which caused my mouse and any usb device connected to rpi not work. Here I give PMF's awnser:

Thanks again.

That is classic over voltage and if you need all of the USB devices you have connected at once is to use a powered USB hub then plug all of your external USB into that.

In that way the USB devices take power from the HUB not the RPI.
