BP M2 Zero setup question

Hello everyone. Today i finally got my os into a card and finally booted up the BP M2 Zero for the first time only to realise that the keyboard i have connected isnt being recognized. I have tryed some methods like 1) unplugging it after the BP is on. 2) connecting a tablet case-keyboard through some dongles 3) 3 different keyboards. Still nothing. The BP i bought brand new and i am confused as to why isnt it working because i couldnt find any similar issues online. Thanks in advance.
