I want to get a USB hub because my laptop doesn’t have enough USB ports. I’ll connect a keyboard, mouse, a USB cable for UART communication, and another cable for programming the FPGA. So let’s say I connect 4 USB cables. What concerns me is that ultimately these 4 USB inputs are connected to the same USB port at the final. In this case, would it be possible to both program the FPGA and communicate via UART through the same USB port? and at the same i will be using keyobard, mouse I hope I’ve explained it clearly.

As far as I’ve researched on the internet, a USB hub should be of high quality, meaning it should be able to provide high power (some USB hubs can be powered by an adapter). However, the question I’m asking is a bit more specific. Because UART is a serial communication protocol. I don’t know the internal structure of USB, but I don’t think we can perform parallel processing. Please correct me if I’m wrong.
