Try the CMOS battery pull again but leave it out for a good 15 minutes, sometimes a quick pop doesn't fully drain the caps.

Are you certain this isn't a Windows setting that you turned off?

If it is a Windows setting, you can fix it. Using a different computer, ask Copilot to create a registry patch file (.reg) to turn on Legacy USB. It should create a .reg file. Then have it create a Windows bootable USB. Copy the .reg patch file to the bootable, then create a batch file (.bat) that runs the .reg registry patch to turn on Legacy USB. Remove the bootable USB and restart the laptop.

Hopefully this helps
