Hi Guys
Thanks for this guide.. but I feel I am so completely out of my depth.
I have a Avalon3 single module, a Raspberry pi bought straight from Avalon.. theoretically it should work out of the box(ish) but alas no..
I have took a second SD card and installed Raspbian then compiled latest cgminer with icarus and avalon2 enabled.. however the pi still can't see the miner
(just to offset hardware issues I have 3 single module miners and can't see any of them, assuming that they all aren't borked) I am pretty sure I'm simply not doing something correctly.
I don't really know what to do with the openwrt-brcm2708-sdcard-vfat-ext4.img image... I've installed it onto a SD card and booted pi with it but it spews out a load of stuff then freezes (I thought the pi was borked until I installed Raspbian).
so I'm a bit stuck

possibly how I start the cgminer is the problem?

edit:
using ls /dev/*USB* to identify the usb being used result /dev/ttyUSB0 although not convinced this is completely right as I have a hub

sudo ./cgminer -S /dev/ttyUSB0 is the best I've got so far... but this time I received the error Avalon2: failed to open on /dev/ttyUSB0
