New cgminer version, 3.2.2, hopefully fixes a lot of bugs with the direct USB behaviour on these devices.
Great. Now just need to properly uninstall the USB to UART stuff...

Even if you use Bitcoin through Tor, the way transactions are handled by the network makes anonymity difficult to achieve. Do not expect your transactions to be anonymous unless you really know what you're doing.

You know, I've rarely had HW errors with my GPUs. How come these USB Eruptors that cost as much as a new gen GPU produce ANY HW errors at all?

Considing it's the size of a thumb, you are being a bit picky. :-D GPUs mining BTC may have low error rates, but mining scrypt all out... anything less than 3-5% is acceptable, and normal. BTC is intensity 8-11(depending on GPU model) and scrypt is usually 13+

Supposedly that is the nature of all ASIC's.

6 - AMU devices thru a Raspberry Pi running MinePeon (6-11-2013 rev) and mining with CGMiner 3.2.1, I can confirm the DLink DUB-7H powered hub does work. I DID NOT use any of the icarus options nor timing when launching CGMiner. I can confirm that the Plugable USB 3.0 High Powered hub DOES NOT work with the AMUs.

Hey, buddy! We've got a similar setup! What's your guess about the ROI of the AMUs? BTW, what sort of cooling are you using, if any?

I was just talking about that, I am not sure ROI will be reached inside of 365 days sadly. There is however a growing market on the auction sites which could be profitable. I have a fan mounted on my rack which moves air across all the mining hardware, I had a usb fan but it was causing hardware errors on a couple of the AMUs, I suspect the fan is a power hog and the DLink did not have it to spare. I have been running for 6+ Hours with NO issues

EDIT: You might need to calculate it individually because you have other hardware besides the AMUs.

I've got the same/similar setup(hub/pi/bfgminer). when i plugged in 7 sticks i had 2 give problems. one was puking errors and the other refused to hash.
i unplugged 1 stick and started a fan blowing across the 6 USB sticks. the 1 stick which was previously giving >10% hw errors started hashing normally. the 6 sticks even after not clearing errors are now averaging ~1% hw errs over 30 hours now. the actual rate should be much lower once i restart and clear the counters. i measured the sticks at 140 degrees F without the fan. with fan they're comfortable to the touch.

How much current does your power adapter deliver? The USB eruptors require 500mA each. The DUB-H7 can deliver 3A, which is 5 eruptors and 1 fan, or 6 eruptors.

So I have 2 USB ASIC Erupters on a DLink H7 connected to my pi (using latest wheezy hard-float build). Got cgminer 3.2.2 installed and it's mining. However, 1 is averaging at 60 MH/s and the other one is averaging 116 MH/s. I have no clue why it's going so slow. I using these current configurations http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/configure-settingsNow when I go a plug the hub into my PC running Windows 7 and I run cgminer with same configs, I'm getting the desired average of 333 MH/s per stick. Since I'm getting my desired hashrate on my windows machine it's making me think that it's a software problem. I though of it maybe being a hardware problem concerning power, but people are posting this hub works fine with 7 usb erupter's connected to them. I only have 2 connected at the moment. I'm running out of ideas. Anyone have an idea of what it could be?

I thought you didn't need drivers for linux? I don't recall installing any or reading that I need to for my pi.

Im using difficulty 128 , HW values seem high . Any feedback would be helpful , I will be moving my hardware to a PI today.
