Non powered Usb Hubs … only support a maximum of 2 Bus powered USB portable drives … anything more, then you need externally powered hdds.
Usb hubs with “switches” there’s oodle’s of them when you do a Google search
ps. if Amazon doesent have them … look eslewhere
pps. i bought a super cheap 10port Usb Hub from China and it works fine … so it’s a bit of “Lucky Dip” with whatever you buy.
if you are worried what you buy is not gonna work … ask about the sellers “Refund Policy” before purchasing.
