hi there i know this has been talked about lots of times and i been through them all but i cant find a solution im using a raspberry pi model b+ and i spent over 15 hours trying to get this to work i try countless fresh starts and i cant seem to find the problem at all i also try different setups and still nothing every time its just says that there are no devices found and i cant add them manually as they don't show up working and stay on standby (solid green) i know they work as i had them working on my computer just want to have them running 24/7 instead of 6 hours a day

any help is gratefully appreciated, also sorry if its in the wrong area.
