I'm trying to compile a custom kernel. At present, here is the data:

Hardware:

Arch Linux default kernel behavior:

  • with computer docked, usb mounse plugged into dock works on boot
  • if undocked/redocked mouse works

Custom kernel behavior:

  • with computer docked, usb mounse plugged into dock works on boot
  • if undocked/redocked mouse no longer works

Where would I be able to track down the specific module/config option that allows me to regain port functionality with the docking station upon undock/redock? I could start with the default config and do trial and error, but I'm hoping it's simpler than that...
