Will there be problems when connecting 3.0 and 2.0 devices to the USB3.0 hub at the same time?

Question

USB

Good time!
I once heard out of the corner of my ear that if there are only 3.0 devices in a USB3.0 hub, then everything works fine, and if at least one 2.0 device appears, then the entire hub starts working in 2.0 mode. I need to connect about 5-6 usb2.0 devices and about 2-3 3.0 standards.
Does the above problem exist on modern USB 3.0 hubs? If yes, what is the best way to solve the problem? Even if there is no such problem, would it be the best solution to buy two hubs: one 3.0 and one 2.0?

Answer 1

I have a 4-port 3.0 hub - I did not notice any problems.
6+3=9 A
9-port 3.0 hub is a lot and expensive. Better buy 7-port 2.0 and 4-port 3.0
