Just a quick update. For grins I switched mining pools to BTC Guild, and the "only half the hash rate is showing up" experience remains. The console shows otherwise, but both Asteroid and the pool are reporting roughly half of the rate the console reports.

So, at least we know it's not something tied to a particular pool (unless both Eligius and BTC Guild have the same issue, whatever it is).

It is interesting, definitely, and curious. The miner output window shows everything is kosher. Yet the pool (and the Asteroid GUI) show half of the hash rate. Doesn't make sense, and I'll look forward to what you find out. Thanks! 

To help illustrate, here's the link to my stats where you can see the 600-700 range using MacMiner's FPGA/ASIC option and then the lower range using Asteroid and cgminer.

I'll try to quiet down and be less of a pest now. 

Oops, forgot to answer this question!

Yes, hash rates reported by Eligius (and other pools) with these devices in MacMiner have reported in the 660 Mh/s range (2x330).

But, the rates in MacMiner were using the FPGA/ASIC miner that he has built in, not cgminer. Perhaps that's the difference?

Here's some more info, which I think is good.

On a whim (and on a different laptop, the one at home) I plugged one miner in, launched Asteroid, and fired it up. After it was up and running, I plugged the second one in.

At this point, the Asteroid window went kablooey--the two miner bars got written on top of the overall bar, so it's a bit messed up UI wise. But, the console shows definitely higher hash rates more along the lines of what I have seen using Bitminter, for example.

So, other than the UI problem that I "discovered" I'd say things are looking up! 

Oh, forgot to mention--if I have just one of the miners plugged in, it runs at about 250 Mh/s rather than 300+.

Very strange indeed!

OK, here's something odd I've observed running on two different Macs.

I'm using a pair of the USB miners. In the "Asteroid" window, both ASICMINER options are checked.

The lower one is labeled 1, the upper is labeled 2.

I start the mining, and things spin up (so to speak).

Block 1 shows it is tooling along at around 300+ Mh/s. Block 2 shows it is "starting."

If I uncheck Block 2, everything comes to a halt--zero Mh/s on both, and they both show "stopped."

Yet, the Miner Console shows the thing is still working.

Odd, no?

Here's the other weird thing. I would expect that if both miners are running that the speed would be 600+ Mh/s, but the pool stats show it's only half that amount.

I'll send a bug report directly to you, Karin.

Trongersoll's comment may be the truest thing ever said here (for the whole week or two I've been around, anyway).

And yet, people are buying the USB miners up and still thinking about jumping in with Butterfly Labs or Avalon (or other producers whose products are on the horizon). Some might actually be placing orders.

So who knows? One thing is for sure: Trongersoll could be wrong. If you get a miner now, then you might be profitable. If you don't get a miner now, you'll never know what might have been.

I'm glad I ordered my pair without giving it too much thought, and I try not to second-guess myself. I'm in, and maybe I'll be profitable and maybe I won't. Regardless, I'm learning some things, and that's not a bad thing at all.

Now this is interesting.  When I paste ls -l /dev/cu.* into Terminal, it shows that I have a Bluetooth modem and a Bluetooth-PDA-Sync device attached. No Icaruses. Yet the miner is running one of them quite nicely.

How about kabi is venting a little frustration?

And, by the way, it's not censorship. Censorship is when you target something because of what it says. It's not censoring when you require people to adhere to certain rules or guidelines--if they do, they can say what they want.

Gee, can we show a little less class and decency?

As for the OP, it's a lose-lose situation. I helped run a LISTSERV back in the day, and whether you're nice in pointing out rule violations or not-so-nice in pointing them out, you offend someone.

Maybe the thing to do, if possible, is simply delete the violating post to be replaced with something like

[Post deleted due to nonconformity with rules. See (link).]

Any way you do it, moderating boards like this is a thankless job. (So, thanks!)

And the weirdness returns.

Earlier, I was trying to get the two USB miners set up with BFGMiner or FPGA/ASIC. In FPGA/ASIC I included this flag:

-S /dev/cu.SLAB_USBtoUART9 -S /dev/cu.SLAB_USBtoUART

because the -S all didn't work for me.

Well, today I restart the miner and it's only finding one of the two USB devices in BFGMiner and FPGA/ASIC. I pulled the one that is working (according to the LED) just to see if the other one went bad somehow. Nope, it too gets recognized and put to work.

The Mac System Profiler shows both devices being plugged in.

For grins, I tried -S all again, got nothing. Also tried "switching" the USBtoUART9 to the second flag in the command, didn't make a difference.

Not necessarily asking for a solution here (although I wouldn't kick one out of bed), but just wanted to provide the info in case it helps anyone else fill in any blanks.

If you're in need of more beta testers, I've got a couple of MacBook Pros that I can test on, along with two of the ASIC USB miners.

Found this in the GPU-README (thanks for pointing that out to me--I overlooked it the first time I scanned down the list of files at github).

Q: Cgminer cannot see any of my GPUs even though I have configured them all
to be enabled and installed OpenCL (+/- Xorg is running and the DISPLAY
variable is exported on linux)?
A: Check the output of 'cgminer -n', it will list what OpenCL devices your
installed SDK recognises. If it lists none, you have a problem with your
version or installation of the SDK.

It appears I need to birddog the SDK.

Thanks for pointing me in the right direction!

Simple question, I hope. If I knew my way around *nix/BSD I might not have to ask it.

Running cgminer to mine litecoins. Upon launch it tells me no GPUs can be detected. The display tells me that new blocks are being detected, but the miner is sitting at zero hashes per second.

I suspect that somewhere once upon a time I did something to disable GPU mining.

Is there a flag or something I can include when launching cgminer that will enable it to find the GPUs and use them?

(I've done a search through the thread using search terms, but didn't come up with anything helpful--I hope I'm not asking a FAQ, and I apologize if I am!)

Many thanks in advance for any suggestions!

OK, I think I've got this thing working now. I put

-S /dev/cu.SLAB_USBtoUART9 -S /dev/cu.SLAB_USBtoUART

in the flag settings and it seems to be doing fine. In fact, I'm getting hash speeds well above what's been advertised for these miners, at times over 500Mhs each for a combined total of 1.0+ Ghs. Now, that may be something odd in the reporting, but it's interesting nonetheless.

So, for the time being, I'm a happy camper (and I'm not TOUCHING ANYTHING!). 

From my miner:

2013.07.14 [07:21]  Work rejected. Server says: Stale or alien proof of work

I had no idea the Covenant was hacking our mining efforts.

A year is about right, with perhaps (probably?) a diminishing ROI afterwards. I'm running a similar setup, but with two USB miners plugged into a powered hub. I get right around 670-671 Mhs, but I'd love to be able to get up to 1 Ghs. I don't know why, it's not like it'll ever be profitable at this low level. A BFL Jalapeño would be great, but who wants to wait months and months and months?

Very nice!

Well, it seems like something's happening, but I don't know if it's all working correctly. So I have a few questions.

1. What about all the connection error messages regarding the server--can those be ignored?

2. What flags can I put in the -S statement so that it gets both USB devices working instead of just the one?

I almost wonder if I shouldn't "erase" the various miners, drivers, etc. from the command line and then reinstall so it's "fresh." But I'm not sure what all I'd have to erase to get to that point. Even when I have tried to run bfgminer from the command line I get similar error messages and things don't look right.

Thanks for all your help!
