Honda USB-C splicer

My 2025 Honda Accord SE has one working USB-C port. The other USB-C ports are for charging only. I have multiple devices (GPS, MP3 player, etc.) that connect via a standard USB cable. I purchased a USB-C to USB adapter to connect the devices to the working port. However, I can't use the devices at the same time. Is there a splicer available to connect multiple standard USB devices to the one USB-C port (or to the adapter that's there)? What type of splicer do I need?
