I'd bet one of the chips is roasted.

A 1TH USB stick would require someone to develop a chip with about an order of magnitude more efficiency than the best currently available. I'm trying to make a stick better than the 2Pac, but even 100GH isn't really feasible for a while.
I am finishing up a 100+GH small standalone miner, and the same form-factor will be used on a 600+GH as soon as I have time to develop it.

Firstly, and secondly, and thirdly - Here, let me spell it out for you. By quoting some replies about six inches above what you just posted. Because apparently people can't read anymore. First off, it looks like you need the 2Pac support thread since you're running a 2Pac.
My first piece of advice would be to check in the 2Pac support thread, since you're running 2Pacs.
I would recommend abandoning this thread and looking elsewhere.
Specifically, the 2Pac support thread.
The software discussed in this thread is two years old. The 2Pac thread is fresh, and includes both a new build of cgminer and a completely rewritten driver that also supports the Compac and does it better than this one ever did.
Advice step number 1 - go read the first post of the 2Pac support thread as referenced above.
It'll point you toward better software. That'll probably help.
Because you're running a 2Pac. I think at this point I'll just stop telling people that, if you're running a 2Pac, you want to check out the 2Pac support thread. |

Can't be done. Learn a little about ASICs and algorithms and you'll quickly find out why.

|

First you have to ask yourself if you're running a Compac or a 2Pac. If you're running a Compac, try the search. If a 2Pac, there is no BFG support.

Are you keeping it cool? 9W per stick is pretty hot, and hotter than 200MHz should require.

Use the search function. It's a known issue with cgminer core.

Fourth of all, there's also no reason to run around profanely insulting people who are giving you quite frank but entirely accurate advice. You f***ing hate people like that on support forumes, but we f***ing hate people like you as customers, which is why I no longer do direct sales of these things. Tired of dealing with jackasses. |

Okay, cool. I mine BTC and don't support anything else, which includes not supporting the conversion of anything else into BTC because I consider that unfair to whoever's holding the bag when whatever crap I mined and turned into a viable currency dissolves into vapor. But my moral compass is a lot stronger than my desire to profit, which puts me very much in the minority, especially in the crypto world. If BitCH or something else ever overtakes Bitcoin proper (based on utility as a means of exchange for goods and services) I'll have egg on my face but that's fine. In the meantime I'm gonna keep chuckling at Bitmain's overt greed and various supporting shenanigans.
In short - BCH can lick a nutsack.
Additionally, hopefully soon I have the time (and parts, and functional firmware) to get some prototypes in the hands of resellers for testing and approval. Looking forward to that. And if I can ever find the battery charger for my camera I'll put up pictures of the thing in operation.

I may open up orders in a couple weeks, when I'm closer to manufacture (or have already started). I'd like to be a little farther along than I am right now. I currently have exactly two complete prototypes, the firmware is still a work in progress and I don't even have a final BOM laid out yet to get cost estimates.

So, a few things about the pod.
Looks like it'll have trouble starting up at extreme low voltage, which isn't unexpected because node voltage balance is pretty critical when it's operating near bottom threshold. Balance also comes into play for stable operation. I looked at Bitmain's BM1384 spec and added 10% to the given stable voltage level for any particular frequency for the test which produced the following results:
100MHz (44GH) 660mV/node 2.64V total; 12V 1.4A for 16.8W/0.38J/GH
125MHz (55GH) 660mV/node 2.64V total; 12V 1.7A for 20.4W/0.37J/GH
150MHz (66GH) 660mV/node 2.64V total; 12V 2.0A for 24.0W/0.36J/GH
175MHz (77GH) 693mV/node 2.77V total; 12V 2.5A for 30.0W/0.39J/GH
200MHz (88GH) 715mV/node 2.86V total; 12V 3.1A for 37.2W/0.42J/GH
225MHz (99GH) 755mV/node 3.02V total; 12V 3.8A for 45.6W/0.46J/GH
250MHz (110GH) 770mV/node 3.08V total; 12V 4.4A for 52.8W/0.48J/GH
Might be able to get more than 250MHz out of it if you ask it nicely.

One of the reasons I don't have investors or shareholders and never will - nobody to convince about much of anything.

Actually, if you're just starting out and looking to recover your investment quickly you do want to sell to the public. Mining takes months to break even, plus the operating cost of power and maintenance. If you can convince someone to pay you a lump sum for the machine, you get paid right now and someone else foots the risk of trying to pay the gear off over the next year.
Also some people don't want to compete with their own customers, they'd rather just get quality gear to people that want it.
Not saying anything about Syan, just that there are different philosophies on how to run a business and not everything that doesn't immediately make sense against your philosophy is automatically evil.

Neither "gecko-comp-freq" or "gekko-comp-freq" are real flags, due to various misspellings or truncations. Anything cgminer doesn't recognize as a valid flag will throw that error. Spelling matters.

If the command line's right but you're not connecting to the pool, I'd guess it's an issue with the port being blocked. Most pools will have a port 80 option of one kind or another, see if that works for you.

Could be because that's not a real flag. Read the first post.

Hence why I mentioned it two days ago.

As with any miner I've ever built or ever will build, the power draw is adjustable. Top clock will be around 60W, more if you've got a Pi plugged into it. I've bought a better bench supply to test with that'll give me good power readings, so I'll set it up next time I get time - maybe Monday if my 2Pac PCB batch delivery is delayed. I can put up a chart of expected power draws at a variety of frequencies.
Should be able to get around 88GH at 35 watts.
