So has anyone actually gotten these to work on a standard Linux machine yet? I keep getting the "Unexpected value 00 received" error. I've tried different git branches suggested in previous posts. I've re-cabled this in various ways also with no success.

I have a Pi somewhere I will try to repurpose for this if that is what it takes.

Try their cgminer branch which got updated recently.

If this doesn't affect hash rate(around 350GH/s per board), just ignore this kind of error. I got several boards with occasional errors like this, yet all works well.

Thanks, I downloaded that branch again and tried it, but same issue. I never get any hashing and I've even tried each board individually.

Most likely a bad USB adapter..pretty common. I had the exact same issue and sold my Prisma off to someone with a BE Controller, and it worked for him. If you do not have another controller you need to find one or sell that crap miner off.
