-S all now keeps the cmd. window open but nothing shows
Ok, try with: bfgminer -S all -D -T -d?

Edit: Also! Be sure you're using the special build I posted for Block Erupter USB!

when i goto that post and download either 64 or 32 bit, norten then removes the file from my computer after download as it is unsafe?

Try the latest cgminer 3.2.0 released today
https://bitcointalk.org/index.php?topic=28402.0

It auto detects everything, auto sets the settings and just runs (No -S options and no --icarus-timing required)
On linux it's rock solid - would love to know how it works on a windows system with that many USB's.
... and a week later ...
We've got cgminer 3.2.1 out now Smiley

Seems there was an initialisation problem that (unfortunately) worked without any problem on my Desktop (Fedora 18) and my Windows VM running on it also.

Finally tracked it down in time for the 3.2.1 release:
https://bitcointalk.org/index.php?topic=28402.msg2397710#msg2397710

Leave feedback in the cgminer thread if you find any problems - thanks Smiley

mine is getting hot, noticed some screws, is the heat sync upgradeable?

Set up the same thing..

i've unscrewed those screws on some defective ones i have - they're all that's holding the heatsink on, and its a flat surface it's on, so yea, there's no reason i can see that you couldn't unscrew it and replace it.

Finally got mine!

Code:
AMU 0:                | 334.7M/328.5Mh/s | A:45 R:0 HW:1 U:5.44/m

It's actively cooled, and alone on a USB hub with two power sources. So I doubt you can do better regarding HW errors (unless the heatsink is really bad?).

Linux users with their own kernel setup should compile/load the cp210x kernel module.
Not quite, there is no module requirement if you are mining with cgminer 3.2.1+ as it uses direct usb communication and will unload that module you just recommended.

I'm surprised no one has really talked too much about this.  Without active cooling mine get hot.  Real hot.  Burn yourself hot.  With a fan on them they're surprisingly cool.

Oh, thanks. Is there a reason for using direct USB communication? More efficient?
Yes, to bypass one layer between cgminer and the device, and give us more control over it. It has allowed us to shave a lot of CPU off by doing so. It is unfortunately a lot more work, and keeps revealing to us interesting hardware limitations that the drivers paper over, but that is often the case that the better solution takes more effort.

Hotplug is sweet!  It worked perfectly on the first try.  Thanks again, ckolivas and kano!!

Would this hub work in the 4 port version? http://www.amazon.com/gp/product/B005NGQWL2/

no the design of the hub could not fit 4 USB's, look at some of the pictures of how they are set up and how much space is needed

the 4 port slim could probably take 3 sticks, the other 4 port you should could probably only take 2.

It is a shame these are not a little cheaper, If I could get a ROI in 3 months I would do it in a heartbeat, 6 months and I would consider it.

If my calcs are correct these things currently will generate 0.01BTC per day, so 199 days for payback excl power/hubs/hosts/group buy fees/difficulty rises.

Taking into account the skyrocketing difficulty increase, these things won't even break even after a year of continuous mining.

Why are we buying these again?

I asked the same question, ASICMINER claim to have sold 4,000 units, that's, right 4,000 x .3GH/s = 1,200GH/s

I just laughed. That's 8,000BTC wasted, you realize how much hashing power you could get from Avalon or BFL for that money? Had you bought 20 x 66GH/s Avalon boxes for 75BTC each and set up a community farm, you would be hashing more than the entire network of Block Erupters, and saved yourself around 5,500BTC. I can't believe that so many people have been sucked in by what is clearly the ASIC ripoff of all time!

At least they are now receiving superior value product than Block Erupters that will actually give them a positive ROI.

BFL in a day shipped more of their entry level 5 GH/s units, with a total hashing power than the entire 4,000 Block Erupters can do combined.
