Hi, thanks for your help.

I already have a good idea of what I am doing, I have a couple of BE cubes and a couple of Antminer U1 rigs. Trying these thumbs to see what they're like.

Followed your helpful guide and built the provided cgminer version on my Pi no problem, however when I run the newly compiled cgminer it does detect the thumbs and shows them as active, but they do not hash and instead I periodically get timeouts from them:

[2014-03-16 22:29:31] DRB 1: Timing out unresponsive ASIC 0

I built the same version of cgminer from the git repo above on my Mac and it detects the thumbs, but not correctly, I get the same message as I was having before:

Drillbit detect (20:7) failed to initialise (incorrect device?)

Think I will just stick to the U1's and cubes for now until hopefully Bfgminer will be updated for proper support for these new thumbs.

I appreciate the input though, thanks.

I'm on Ubuntu on a dual Coppermine rig... and switched to BFGMiner to eliminate that kind of error then found out it's a power issue. I will have to assume you are using one powered hub. I've ' borrowed ' a wireless router's power brick for a steady 2.5A @ 5V and have also found out the power rails IN the hub won't let me have too much draw on either side of the 2nd hub ( 7 port hub, 3 ports from one end, 4th goes to the second IC letting the last 4 count as a different power rail too ). Point being, check your power as I get that kind of error ( don't have any drills to test it on, from what I read, they use more than an Ant ) when I reorder what i've got plugged in.

Good luck.
