Usb hub for mobiles proxies

Hello, i have created multiple mobile proxies with raspberry and dongles and i rotate ips using rasberry reboot method. I am looking for methods to scale this and i have read that people using ubuntu with usb hubs. Which usb hub you suggest for that? There is a big list on uhubctl

Omg, every modem has api to change the IP address. So no need to reboot it .

Anyway, Orico hubs are good. Just ensure the hub has external power source, and watts per single usb slot is higher.

Also usb slots must be layed out like row of llll not row of hyphens --- , so modems (sometimes wide) don't overlap.
