In this project the maker of the project desolders and removes two of the USB ports on the Pi and solders on a USB Hub to the pads at the bottom.

I'd like to solder devices to the USB pads in the same way and would like to know if I can do the same while leaving the USB ports in place.

Will the USB ports still be usable this way? Does doing this effectively add a new USB port?

  • Will the USB ports still be usable this way? yes, but Does doing this effectively add a new USB port? no. It's either / or. You can only use one device per port (unless you connect a hub, of course) – Dirk Sep 24 '18 at 9:37
  • If I had a device soldered on to the pad and accidentally connected another one to the USB port, what would happen? Will the second device simply not be activated or will I lose the first device and switch to the second one? – user942937 Sep 24 '18 at 10:11
  • Or you loose both? TBH: I don't know, could be any of several scenarios – Dirk Sep 24 '18 at 10:29

Yes, you can solder a device directly on the PCB without removing the USB ports.

It will not give you extra USB ports. If you connect 2 devices to the same port the most likely outcome is that neither device will function properly.
