Usb Hub with multiple controllers

Hopefully this is the right spot for this?

Hello! This is going to be very rambling, i am not the best at explaining, my apologies.

I'm messing around with a project using a midi keyboard with an Uno with a midi shield. My laptop (a Lenovo Ideapad 5i if thats important) has two usb-a ports and two usb-c ports, one of which is also the charging port. Both the keyboard and Uno of course each require one of the type a's, I also like to use a wireless mouse with a driver that plugs into the laptop, which i have a type c to a adapter i can use for this. However, I may also need another uno board, which requires another port.

What I'm wondering is, if I plug both unos and either the mouse or keyboard into a usb hub like this one ( Amazon.com ), will I still be able to use both microcontrollers?
This may be a stupid question, but figured I'd ask before buying a hub that may not help.

Hopefully at least some of this made sense, thank ya'll for the help!

Once a sketch is uploaded to an Arduino, only power is required to run the sketch. USB is one method (of many) of supplying power.

Only one USB A or C is needed to program the MCU, the other devices just need power and the HUB will work great for that.

Try not to limit yourself. If your hub is now already full you might have a problem in the future.

I have always used 7-port hubs. When my last one died I did buy UH700 | USB 3.0 7-Port Hub | TP-Link. It has a power switch (only works when external power is connected :frowning:) and therefore I can switch all connected Arduinos off at the same time when I have to change wiring between them.

At the moment 4 Arduinos connected and a logic analyser; leaves 2 ports available for future expansion.

It is more expensive though than the one that you mention.
