How would I get more usb ports on a Raspberry Pi? 2 just isn't enough.
The obvious answer is a hub, however I have tried many and none work.
My friend said that most hubs drive power back to the pi, which it doesn't understand. He bought a hub specially designed for Raspberry Pi, and it works fine on his but not on mine.
Is this because he has a more recent OS version than I do? We both are running Raspbian, but he has a later version than me.
