Steam Controller Bluetooth and Calibration Issue (Fixed)

[Life Alchemist]

When I originally plugged my controller into the dock and steam deck, it initially worked after pulling it out of the dust after several years, but the bluetooth was not working at all. Eventually, I ended up in this discussion thread:

1. And the advice was to use this update in the link with my steam controller plugged into the computer:
https://steamcdn-a.akamaihd.net/steamcommunity/public/images/steamworks_docs/english/Steam_Controller_FW_Update_Tool_5b0f21bd.zip

2. I extracted the folder (along with various different repeats of debugging), executed the prod.bat file and waited for it to update. Then, I executed the ble.bat file to update it as well.

3. From here, the steam deck found the steam controller through bluetooth. Except, now I had the problem that the calibration was all broken. I even thought someone hacked my steam deck because simply placing my thumb on the trackpad ended up moving my mouse erratically and clicking multiple things I didn't click at all.

4. A lot of places recommend pressing the Y + Steam button, but that didn't work for me. Instead, I had to first do B + Steam, wait for the sound confirmation and the steam button light turning off, THEN doing the Y + Steam button pairing. Finally, it worked!

Hopefully this helps some people out there struggling with the same issues I did. The steam controller 100% works with the steam deck after some struggling with some firmware updates and other debugging.
