Thanks for the heads up.  I've only briefly browsed the forums here, and even than I've heard of Josh.  Josh is right, it does offer publicity but I don't it's the kind of publicity they want.  As I'm about to make my first substantial purchase of mining equipment I had considered BFL but I'll shop elsewhere now.

I know of a few other manufacturers but if anyone has any suggestions on a reputable company with good communication and won't screw you over, please let me know.

PS - Thanks LittleD for the twitter follow! 

Hi,
Please forgive if this is answered elsewhere - I've looked and all I'm pointed to is the development of new DLLs.

I'm trying to run CGMiner on Windows Server 2003 (fully patched and up-to-date). 

CGMiner loads fine and gives me the standard "open-device-failed, need to install WinUSB driver err-12" message.  I've already installed the Silicon Labs drivers, and when I load up Zadig to change the driver there's no option for 'WinUSB'.  The only two options available are 'libusbK (v3.0.5.16)' and 'libusb-win32(v1.2.6.0)'. 

I'll continue to research but if anyone has any input it would be most appreciated.

Wow, lots of information - definitely more than I ever would have imagined.  But it all makes sense now.  I've discovered that the "magic number" of BEs in the Satechi is only 5.  I'm running a few more off other ports, and added some to my laptop.  This should suffice for now, until I can come up with a better solution.

Thanks everyone so much for the insight.

That seems about right ... I've also been working with some helpful people in the IRC channel - it looks like the magic # for me is 5 BEs.  I'm not getting anymore 'nonce/HW' errors.

I'm still somewhat new to mining, so I'm starting out with a Satechi 12-port powered hub.  I have a total of 13 block eruptors.  I can invest in more hubs easy enough.  I've reviewed the specifications on the Satechi - each port provides 5 volts, 250 milliamps.

Argh,   

CGMiner is now showing all AMU devices, but those above AMU 3 are randomly showing 'invalid nonce - HW error'. 
They're on a powered hub, but some consumer feedback indicated that the necessary power wasn't being sent to all ports in the hub.

Any thoughts? 

Works great, thanks!

Hello everyone,

I've gleamed a lot of knowledge from here - thank you to all who have shared some insight.  I have a small question though - I have a total of 13 ASIC block eruptors I'm using with CGMiner v3.3.1.  The statistics portion shows an average of ~4.0 GH/s which seems to be correct when doing the math.  My question is that the command prompt window is showing only six AMU units (0 - 5). 

It's only been configured this way for a few hours - the statistics in my pool haven't updated (as I recently added ten of them, I'm guessing I should see a significant change?).  I'm using Slush's pool and the average stats are based off of the last 10 rounds.  So my questions are:

1.  Should I investigate why CGMiner isn't showing all ASIC units, and
2.  Based on others' experience, when should I see an update visible in my average hashrate in my pool?

I apologize for the noobish questions.  Thank you all so much for your input!

I'd offer that GPU isn't necessarily obsolete.  I have an ATI Radeon 6850 and getting ~ 170 MH/s on it.  It's complementing my other hardware
