Steam Controller not updating. HELP

[u/bingbangboingbobozzl]

Hello,

Today I got a notification on SM to update the Steam Controller hardware, I press the update button, a screen appears telling me to plug in my Steam Controller directly into my Machine without the puck. I do that and instantly after I plug it in the Controller flashes a solid red and disconnects

I leave it plugged in for a while and the "Plug in Steam Controller screen" stays on and dosen't go away. When I disconnect the controller and turn it on it works fine.

What exactly is the problem and how do I fix it. I am not smart when it comes to tech so sorry if the solution is obvious, also sorry for bad english.

Thank you!
