Hi, thanks again for your reply.

bfgminer -S all i get "The request is not supported"

trying just

bfgminer -S all ?

Hi, thanks again for your reply.

bfgminer -S all i get "The request is not supported"

trying just

bfgminer i get this;

try --scan all or --scan compac

your screenshot tells me that there seems to be another problem here.... if both cgminer and bfgminer have problems using your USB ports....

maybe a BIOS setting / driver update ?

I agree here.  This feels far more like a windows/USB issue.

Along with trying zOU's suggestion - try cgminer with the --ndevs flag (cgminer --ndevs)

It should feed you output similar to the --scan option I believe.

Hi thanks again, i agree its odd. However i have tried multiple windows machines and they all get the same error.

cgminer --ndevs
gives me this;

the bgnminer command just freezes and never shows anything.

I don't know if you mentioned earlier, but I see you're using bitshopper Compacs. And the Windows build of cgminer-gekko. I don't know what the BFG hangup is, but the Win32 cgminer-gekko someone compiled off the old version; we updated it to support bitshopper sticks and I bet nobody's created a Windows build since then.

What do you get with stock cgminger 4.9.2 with Icarus support (which I believe the default Windows download includes)? If they detect at all they should come up as Antminer U3.

Also, someone previously asked if you had made sure to grab zlib1.doo or whichever it's called; this was somehow left out of the Win32 archive but cgminer needs it to work properly. A stock cgminer Windows archive will have it.

4.9.2 works! 4.9.1 give me the permission errors

I could kiss you all! thanks so much for helping!

Question: I'm having to use --au3-freq to set the frequency. Going over 250 says invalid frequency.. Anyone know any away around that?

Now i need to change the pool / address

Random question maybe offtopic but i run a Full node. Could i just point cgminer at the full node rather than using a pool? does anyone have a link they wouldnt mind sharing for me to look at. (I am planning on solo mining) thanks again!

[sidehack]

Stock cgminer doesn't support higher frequencies than that. A U3 would catch on fire.
You'll also probably see "no valid hashes for 2 seconds, resetting" pop up every now and then. You're only running about one-fourth the hashrate cgminer expects from a U3 device at a given frequency so it doesn't always report back as quickly as expected.

The only way to do better is to get the cgminer gekko Windows build working. Or BFG5.4

[Mikestang]

4.9.2 works! 4.9.1 give me the permission errors

For future reference in this thread, that is because there was an undocumented bug in 4.9.1 where it would not recognize the Antminer U3 (which is what the Compac stick is recognized as if not using cgminer-gekko).  4.9.2 fixed this bug and has some other changes that were specific to the U3.

Yes, you can solo mine against your own node, but you are better off solo mining in the ck solo "pool".  It's not really a pool, but it has much better network connections than any of our home nodes could have, so if you do solve a block you have a much better chance of it being accepted first from ck solo than if you mined against your own node.  See the ck solo pool thread for more information in this regard, https://bitcointalk.org/index.php?topic=763510.

I don't know how to mod a hub. I have a soldering iron and can follow a detailed guide, but until there's one then I'm stuck.

I'm in the UK so I can't get the awesome US hubs. The only hub that seems good is £70 and there's no way I'm paying that. Then there's a few others, but I would have to risk it and hope that every other port supplies 1.8a. I can't afford to risk it and buy several hubs.

I just want to be able to mine at 15GH/s. Why is this so difficult?!

@Morguk and @Shelltux

well, it looks like Plugable usb 2.0 powered hub slots can support ~17.5-17.8Gh/stick (~750-760mv, 325mhz) without Y-cables, although I am running just two one sticks now. I will try to see if I can go to 340mhz, but I don't see why not. This Plugable is 60w, although 10A max among 7 slots. The hub is basically room temp by touch and I provide small breeze toward the stick (nothing much). I use pi zero with it, but I am sure that it will work on basically anything since it is usb 2.0

£35 vs $35 for US one, but better than £70

Two sticks at 325 On Plugable:

Raspbian gurus: While trying things on a pi with sticks (the only thing on topic here), i deleted the wastebasket from the pi desktop and although I can go to File manager>Go>Rubbish bin to see the contents, I would rather have it on the desktop.

Is there any way to recover it (wastebasket) on the desktop aside of reinstalling the whole Raspbian from Noobs?

Thanks Biodom. Any idea if I could get 4 sticks going at that speed?

i tried three sticks- Plugable got a bit worm, but not superhot. Four "might" be possible at these settings, but I will not try today.
I would start four at lower mv & mhz-just an opinion

Interesting: three sticks at ~52-53 Gh/s total (~17.66/stick average) were using ~33W at the wall.
Without any load Plugable uses 2.2-2.3W at the wall, cannot easily measure how much of 33W is hub itself under load.
My point is that when you go for high speed on fancy powered hubs, J/Gh for sticks will worsen, as expected.
In this particular example, it is 0.62 J/Gh (when overlocked at 750mv/325mhz) using "at the wall" numbers.

[dan91]

thanks for all the help, however i seem to be having another issue. After 3-10 mins the blue light stops flashing and the core V goes to 0 from 0.678. I am unsure as to whats going on here. The only thing i have noticed is the back of the chip does get HOT (too hot to touch for more than a few seconds). I am wondering if this could be the issue or maybe if i am missing something?

[sidehack]

If the stick is getting very hot, you should put a fan to it.

I have a fan on it already. I am unsure as to if the heat sink is working properly :| What about the light and Core V dropping to 0?

Check the screws at the heatsink! Maybe they will get loose or they get stretched by heat. Its a cooling pad under the heatsink, not paste like the originals. My bitshopper-Stick has the same problems with heat and dropping VCore but i havn't the time to sort it out yet. Maybe you get the clou ...

Yeh i checked the screws before they were loose so i hand tightned them a bit. Just at a loss of what to do really. It wont run for more than a couple of mins before it stoppes and the V core goes to 0... It is a bitshopper stick. Really dissapointed.

[zOU]

I think you're overloading the USB port.

What freq are you running it ?
