A2779 820-02841 - hole in a trackpad connector - way to recognise USB KBD/Mouse without login into the system?

[it-solve]

Got this macbook with severe short on the tpad connector. Managed to drill enough under the tpad connector to remove the short. Now it turns on but cannot enable USB mouse/kbd without loging into the system to extract the data.

Is there a way to kick in the keyboard without tpad connected?

Internal keyboard is connected to trackpad circuitry.
Its information goes to CPU through trackpad.
