USB and HDMI ports not working

Hello everyone, I just unboxed my ROSBOT3 PRO and this is my first day with it. I followed the instructions on the manual and on the youtube video to plug the batteries and wifi antenna. While following the tutorial, i arrive at the step of pluuging the ethernet adapter to the computer. The problem is that i get no signal. I tried testing the ports with my mouse and my USB flashdrive but nothing. Same for the hdmi i tried multiple cables and screens but there is no displays. I checked if the batteries were the problem but even when plugged straight using the DC in port, i get the same result. The robot seems to boot just fine. The pwr led is static red, the L1 is static red, and the LR1 led is static blue. The L3 led stays on but fades out every 8 seconds for around one second. Can someone help me with this problem? My robot serial number is 682ea2.

Kindly,
