Hi guys! I am confused if I would need a powered usb hub or not because currently I have a Raspberry Pi Model B,I am planning to connect a canon printer, an Edimax EW-7811U,keyboard,mouse?


Thanks!!

Get a powered usb hub and isolate it so you can plug in anything without worrying about it.
If you want to avoid a powered hub look up how much wattage your devices pull... or you know just try it.

I bought a powered hub but when I plugged it into the RPI it booted without the power supply but its full of error :'( so what I did is that I plugged the Micro usb and the hub, would it backfeed?

Cheap hubs will back feed power with a Pi B, yes. You can stop it it doing this several ways, or you can live with it, its not usually a problem in my experience.
