@sleshi you have one USB port that is soldered to the USB/card reader board. The part number for that board on a HP 15-db0000 is L20448-001. The other two USB SuperSpeed ports are soldered to the motherboard. For that you need to either match replacements ports by dimension and contact orientation or get a broken board from places like ebay etc. and harvest the ports from there. Personally I would find a motherboard to use as a donor board.
To work on replacing the USB ports, you will have to remove the motherboard. Use the [document|39925] to work on your model.
