How to enable touch screen on MINIX product

Dear all,

I get in hands a MINIX Android player which is dedicated to digital signage. The firmware is running Android Kit kat or Lolipop.
Actually the idea is to test this device with a big capacitive touch screen connected to USB.

First boot I run, touch screen was not working at all, so I guess drivers are missing for the screen

I have not an android expert so I need to know what it is need to know to get touch screen working :

• Does the firmware need to be rebuild with touch drivers in ?
• Does drivers can be simply place in a particular folder and then Android is smart enought to load them ?

Thank for you help

regards
