I"ve just bought myself a Pi and have never found the need with a home computer to need a USB hub. Obviously with only two ports and no PS/2 connection, this is different with the Pi.
On the FAQ, the site says that the Pi"s USB functions can be expanded with "a USB hub". So, I went and bought myself a cheap USB hub, unpowered, which I thought would be sufficient. However, subsequent online searches and looking through the forums have revealed that I"d need a POWERED USB hub. And now I"m stuck with an unpowered one and am a bit strapped for cash.
I don"t want to damage my Pi, but after a bit of Googling, decided to ask your opinions. I only want to connect 4 devices at any one time - a mouse, keyboard, bluetooth dongle and WiFi adapter. Would an unpowered hub be sufficient for these, or would it cause errors and damage to the Pi?
Thanks for reading
