So your suggestion is for me to run another OS?  Hmm, that seems like quite a reach just to get a couple stick miners hashing.  My XP machine is my main computer, I use it for a lot of stuff including my bitcoin node, not sure I want to go messing with additional operating systems...

I understand how to use zadig, that is not an issue here.  As shown in my post I am specifying a frequency.

I am having difficulties with bfgminer530 and the compac usb sticks.

First, no hub with bfgminer using .bat = bfgminer.exe -o [pool] -u [user] -p [pass] --set compac:clock=x0b83

1) bfgminer530 will not see the sticks on my old WinXP box.  Neither starting bfg with them (or just 1) plugged in nor hot plugging while bfg is running wakes them up.  The program just sits there and asks me to add hardware.

2) bfgminer530 on my Win7 box sees the sticks, however I get comms errors.  Here is just 1 stick:


3) when I plug a 2nd stick in the errors happen twice as often:


Any ideas what is happening in both cases?

My 4 compacs showed up yesterday and I'm having some problems.

First, no hub with bfgminer using .bat = bfgminer.exe -o [pool] -u [user] -p [pass] --set compac:clock=x0b83

1) bfgminer530 will not see the sticks on my old WinXP box.  Neither starting bfg with them (or just 1) plugged in nor hot plugging while bfg is running wakes them up.  The program just sits there and asks me to add hardware.

So I tried cgminer-gekko to see if I would have better luck.  I cannot use cgminer on my Win7 box because zadig doesn't work on that machine.  So on a powered hub with cgminer-gekko using .bat = cgminer.exe -o [pool] -u [user] -p [pass] --compac-freq 150

1) a single stick works perfectly, no errors

2) edit - new usb hub and ran 2 sticks on xp laptop just fine, old hub was crap, will update soon >2 sticksplug in a second stick and all goes to hell, LIBSUB_ERROR out the wazoo and both sticks only hash around 2GH.  I didn't try more than 2 sticks.


Any ideas what's going on here?  The errors on the Win7 box are very confusing, I did not expect any issues there.  I'm thinking most of the fail on the XP machine is probably just the fact that my old WinXP box is old so I'm not too concerned there (gotta build a new computer one day...), but I can run 6 nanofury usb sticks on it at the same time no problem.  In fact I can run the 6 nanofury sticks in one instance of cgminer and 1 compac stick in cgminer-gekko at the same time (pictured below), zero issues, so I'm at a loss why more than 1 compac grinds it to a halt.

So did mine, way sooner than I expected!  Can't wait to get tweaking on them.

Got my compacs yesterday, only started playing with one and pointed it to the club @ 150 frequency:

Let's go, gekko block!

This has been happening for years with medical cannabis dispensaries in California.  The police bust in to a California law abiding business, take all the cannabis, money, computers, video surveillance gear, etc. etc., and then say have a nice day, we may file charges against you.  Charges are never filed and all that stuff now belongs to the police.

What a deal, no wonder they don't want to change it.

Civil asset forfeiture is a hot topic right now, it's total bullshit.  Unfortunately here in California we just had a promising reform bill shot down by misrepresentation from the law enforcement lobbies.  Most of the California forfeit cases deal with cannabis cultivation.

The scary thing is, when you get to looking at civil asset forfeiture, they really don't need any reason to take your stuff, you do not need to be accused or convicted of a crime, and you have no recourse to get it back.

Thanks for the explanation, most of it got through my thick skull.  You started to lose me with the components, but I think I get it.

So upon further inquiries it appears that my hub is not going to be good for overclocking stick miners (post).  I'm going to pick up one of those usb testers and play around with this hub (afterall, playing around is most of the fun), but if I'm going to be running multiple sticks overclocked I'm going to have to look for new hardware.

Kinda my thoughts, too, especially given how beefy they appear to be and how expensive they are.  Oh well, live and learn.

Bookmarking this thread, I'll be pointing one of my sticks here as soon as they show up.  Looks like almost 400GH going, it's like an S3, not too shabby!

A more complete answer from the CoolGear USB folk:


I bought this hub originally because of the chip it uses inside, it was supposed to help with running more than one U3 at the same time, which it didn't.  I think I'll play around with it a bit, but it's not looking like it's going to be suitable for 4 compac sticks if I want to do any overclocking.

Download from a link in the OP and you should be ok.  You can verify the sig and pgp key if you are still worried after the download, or you can compile your own copy.

Thanks for accepting me, new rules noted.


What is QS?

Any my high 5 percentage was looking so good for so long, looks like we'll have a sub-5% diff change this go which is much less that we all thought at points during this adjustment period.

So 3 compacs OC'd equals roughly a U3, that's pretty cool.  Much less power use, much less hardware problems, and made by a member of our community, not some Chinese mining conglomerate.  Can't wait for my 4 to arrive!

Finished resyncing the blockchain (again...) and my payment from my previous signature campaign came in.  I also earn a few thousand satoshi every day in my HaoBTC investment account.  It used to earn more when I had more deposited, but I spent it on some new stick miners for fun.

So how do we get one of those fancy sticker? 


It's not a wallet, it's more like a savings account.  You deposit btc to your HaoBTC account from one of your wallets and watch the bitcoins roll in!  I only have a little in my account at the moment, but it's like free microearnings the way I look at it, until I deposit more.

You led with the "bit", and followed with much fury - I'll give that one to you, but only because you're so generous.   

But that gets regulated internally to 5V, right?  I think that's what you wrote in response to me in your stick thread.  I guess that's one disconnect I'm struggling with.  Internal ratings, external rating, usb port ratings...  Were those numbers (12V @ 5A) determined from manufacturer literature or experimentally?  If every hub regulated voltage down internally to 5V where do the differences between hubs come into play?


Here's where I get lost.  What makes a hub "beefy"?  This is directly related my questioning above.

Would a single usb 3.0 port be essentially equivalent to a y cable on two 2.0 ports?

You have to physically de-power the U3 (both usb and 12V).  Unplug, count to 5, plug back in.  Sometime I had to do that more than once to get them going again.
