I have an HP 15-u011dx laptop and my devices have not been connecting to the USB 2.0 port properly. A device will only connect if the connector is held at a slight angle and if it's not plugged ALL the way in. They all work fine on the 3.0 ports so it is likely a hardware issue with the 2.0 port itself.
Here are pictures of the PCB containing the USB 2.0 port (as well as the headset jack and the volume control buttons):HP ENVY x360 USB 2.0 board:

It seems that you have the board taken out. That makes life a lot easier. I would start by sacrificing a USB cable and do continuity test on each wire. Alligator clip would help while you wiggle the port to test for lose.
If you can identify the wire or position that is loose, you can try fixing it with super glue or re-solder.

From your description and the look of the board, it doesn't seem likely that the problem is related to loose soldering. Rather the problem is either with mechanical deformation/damage of connector contacts, or with contact contamination or wear, which is nearly impossible to repair.
If you want normal reliable USB connection, the best course of action would be to buy the entire add-on board from e-bay, or genuine HP replacement part DA0Y61AB6D0.
