The manufacturer? I thought these guys were discontinued?

If the chip warms up but the LED never flashes white, I'd consider that it is hashing but the return data isn't getting back to the USB chip. That would indicate a bad solder joint on the ASIC. Or the ASIC is toast and it's just pulling power but not working. Either way, I'd first talk to the guy you bought it from and then talk to the manufacturer about fixing it.

Thanks for the reply. Yes I've tried searching the forum for similar issues but found nothing. I've done just about every kind of trouble shooting including unplugging and plugging the stick in while cgminer is running.

Yes the chip does get hot when cgminer is running. What does that mean? So you basically think the chip is fried?

I got it off of ebay

That looks like a first-batch version and I would guess it was run very hot for a very long time. Probably the chip is toast. Who did you buy it from?

I'm assuming you've tried unplugging the stick and plugging it back in while cgminer is running. Does the stick get warm at all when it's plugged in with cgminer running? Have you looked over the troubleshooting steps in the first post, or searched the thread for advice on similar problems?

Hello,

I have two gekkoscience miners. One I bought a while ago and another I recently bought. I was able to successfully run the first miner I got, but I'm having trouble with the second one.

I'm using the version of cgminer that is posted on this thread (the one that is modified for this miner). As soon as I start cgminer, I get an error saying that the miner hasn't submitted a hash for more than 10 seconds. Then I get another error saying that cgminer has tried to restart the miner, but it was unsucesfful due to the error: libusb_sucess. And this error keeps on repeating.

I've tried reinstalling the zadig drivers and have played around with the voltage dial on the miner as well as changing the .bat file configurations. This is my configuration:

cgminer.exe -o the pool I'm using -u my username -p mypassword --compac-freq 170

As I've mentioned I've played around with different clock speeds.

I'm using a powered usb hub (the same hub I used to power the first gekkominer I got). I am not plugging in the two at the same time, so I know it's not some kind of a conflict error or power issue. This miner simply won't mine even when nothing else is connected.

What can I do to fix this error? I'm literally using the exact same conditions as I did for the first gekkominer.

In addition, I noticed that on the back of the gekkominer (where the chip would be on the front side) is a brown spot, almost like a burn mark....like the chip might have been fried. I've included a picture for you guys to see. The bottom one is my original miner for comparison and the one on top is what I recently bought. Should I be concerned with this brown spot?

I guess my question is: Could this chip be dead? Or am I just inputting something wrong?

I would love some help!

+1 for being interested in a newer GekkoScience Compac USB!!!    Love those things

You have another miner project going? Inquiring miners want to know. 


I'd definitely be interested in an 8-port hub.

If there is a new GekkoScience Compac USB miner with a newer hashing chip in the works, I'd be interested in that, too. My current Compac is pretty near bulletproof hashing away at 325 MHz as a lottery miner.

Cheers,

What I'm working on right now has a manual master adjustment which means every port will have the same limit but it'll be user-determined. When any one port exceeds that limit, power for that port will be latched off until the user resets it manually - I'll have a button on there for each port, and probably a bi-color status LED. I'm not a fan of self-resetting because if the problem persists you'll just end up with something cycling until there's manual intervention anyway or something burns up and then what was the point.

I'll probably add an eighth port that's power only, for charging or fans or whatever. Looking at the same 7-port controller used in the 49-port Eyeboot hub (and a couple others I have) since I know it's decent.

I like the idea of the wide input voltage range. I'll have both a barrel jack and 6-pin for input, and the barrel jack means you could use something like a 20V laptop brick if you wanted. Course if you wanted to pull 3A per port and used a 12V brick you'd end up melting the jack like an idiot, so that's one point of concern. But idiots are gonna find a way to mess things up anyway.

Novak and I talked about building something like this over a year ago but we got sidetracked.

@ Sidehack, since this does relate to the sticks, about a point on your To-Do/In Progress list in another thread:

I've been thinking for a while it should be a great product for you to make/sell. Both for miners and Industrial use. Tried COTS powered hubs in our systems - terrible lifetime. Now use Tripplite's Industrial hubs. Very nice and in no respects cheap.

Per-port current limiting good idea but be sure to back that up with a self-resetting PTC 'fuse' either also per-port or at least for the incoming power.

Still running these sticks myself.

 

I still have two 19 port hubs with better psu's  so I am set for the newer sticks.

But if you sell the hub and PSU, what are you gonna do when a newer better stick comes out?

Note I have used sticks and I am selling them 


https://bitcointalksearch.org/topic/looking-to-sell-my-compac-sticks-all-sold-1613901


will also sell the hub and the high efficiency  psu

Several people asked me the last days if and when I will restock:

EU Version (bitshopper.de manufactured) of GekkoScience BM1384 Compac US stick miners officially sold out.
Additional production batches not planned due to unavailability of ASICs from Bitmain.
 

Does you have a shipping cost table for inside USA? Sorry for my bad english.

Sorry for the bad english and the dump questions, but I need to understand this data: I'm using a GekkoScience Compac BM1384 Stickminer and I'm getting this information: 24.54 / 24.11 / 10.76 Gh/s
https://cloud.githubusercontent.com/assets/4379316/18424752/9b0850e4-7880-11e6-8b7a-8c491e1da482.png

I read the README file but I can't understand the meaning of "20 second exponentially decaying average hash rate".

Does this means that I can run up to 24.54 Gh/s but I'm running 10.76 Gh/s?
Or
Does this means that I'm actually running to 24.54 Gh/s but, for some reason, my pool is accepting less than a half?

And my second doubt is about the income info, which its says "I: 509 nBTC/hr":
Does this mean that if I use my device to run solo mining I can get 509 nBTC (0.000000509 BTC) every hour?
Or
Does this means something else?

Thanks in advance for your answers.

Well daggum that's super handy.

I have stock, just updated the listing.

Also, I've been shipping out units to my customers with a support document that includes a link to my compilation of Cgminer-Gekko along with the missing dependencies, zadig, zadic command line tools, and a batch script which registers the win-usb driver for compac without ever having to use the zadig interface.(Just plug in your miner and run "InstallWinUSBDriver.bat")

For those interested, the document and binaries are available for download here:

Everyone using cgminer-gekko faces that issue. It's a bug known since about a hundred pages ago that was never fixed.

Aaaaaand this did the trick. Unplugging + Plugging. It is hashing. Just to let you guys now: If you want to keep these routes after a reboot you need to ad them via:

Now the only problem left is that cgminer crashes every time I tell it to write his config.conf. Yes, it is an elevated command prompt. Yes the directory is writable. This happens every time. Anyone facing the same issues?
