That would be a very strong NEGATIVE

I have used this exact hub filled up - up until the other day running bfgminer and/or cgminer with the old block erupters and most recently the Bitmain U2 USB miners....So that theory is incorrect...I would say it is a software issue at this point as there seems to be a forum filled with buggy software.

thanks!

That actually looks like a qualified powered hub!

What does that mean exactly?

Does the software of bfgminer work? or is it something specific on my end you can elaborate on?

thanks!

Yes ive tried the both no luck yet.

Hi,

I'm running BFGMiner version 5.4.0 64bit on win 7 64bit ultimate.

I am trying to run the GekkoScience Compac UBS's in a powered USB hub.  I have 5 of the USB miners.

I'm using an Anker 10 port Powered Hub: http://www.amazon.com/Upgraded-Anker-SuperSpeed-Including-Charging/dp/B005NGQWL2  mor from the manufacturer: http://www.ianker.com/product/68ANHUB-B10A

I keep getting this error:

CBM 0: Comms error (werr=1)
CBM 1: Comms error (werr=1) 

I had 1 USB miner in the hub and got those errors then it started to go away.

The first one was hashing at stock about 8 GH/s and the second the same

I ran a .bat file  as follows:

bfgminer -o stratum+tcp://stratum.antpool.com:3333 -u xxx.x -p x --set compac:clock=0x0b83

I also tried:

bfgminer -o stratum+tcp://stratum.antpool.com:3333 -u xxx.x -p x --set compac:clock=150

I am not sure why im getting this error.

I did also try the cgminer version and ran zadig, but that didn't work for me, so i removed the zadig driver.

I just removed the second compac and im still getting the errors.

do you have pics?

if youre not looking for an S5, then you might want to change the title of your post 

Item(s): 1 or 2 TB SSD ( please list available brands you can get)
Grade of interest:3
Number of items:2

The problem you are having is that you are low balling offers for a miner which still is efficient and powerful. 

You are speculating on diff rises on non existent miners. Aka the SP50.

And the S7 has been out and running for about a month already.

So your theory is incorrect. And it seems you are a bit snarky about it.

If people offer to sell you their gear for a price you don't want to pay, then don't buy it. Plain and simple.

Trying to intimidate people to sell you their gear at rock bottom prices because that suits you is why you keep experiencing deals that "fall through"

Unless you have a crystal ball and know what the BTC price will be in a few months and what high end miners are Actually availe for purchase besides the S7, then I think you will be waiting longer.

You speak of bitmains "crappy" 4.6TH. miner. I still don't get what you trying to accomplish by saying that.


You are looking to buy 5 x S5's for next to nothing while bashing the same company that makes both miners.

That in effect makes no sense.

Truth is the S5 is an excellent miner, which still makes coin. Depending on electric costs etc.

Good luck with trying to pay nothing for something of value.

Thanks!

yea they aren't going to sell you 20 of them, say you have 3 million  $ to spend and you might get their attention

why would you assume that it would cost 20K?

have you asked? what is the minimum bulk order you are referring to?

misinformation is a terrible thing.

thanks!

how much did you get a quote for the SP50?

Curious? you seem pretty sure of all of the above?

its ok to look for a good deal on here for miners even if they are still very current, but you seem to think that once the SP50 and loads of S7's are in peoples hands, you will buy S5's for nothing?

good luck with that, they still make decent coin, especially if you have low power.

How much was the SP50 again?

thats what i thought?

pleas tell me if im wrong and you have an actual quote on the price.

thanks!

I think it is safe to say this sale is not designed for an upgrade to a more efficient setup for ManeBjorn, It is probably as he says, to simply pay bills

ManeBjorn is a stand up guy, major contributor to the scene and is a reputable member of the community.

There would be no concerns for anything if considering purchasing any miners from him.


thanks!

I can vouch for mindtrip, I have bought miners for him and vice versa.

Honest guy, straight shooter.

thanks!

where is it shipping from?

do you have a pic with model/serial#?

thanks!

That's crazy!

That guy should be fired!

If that's what they do at your front door, imagine what goes on before they get to your home!

These guys need to look out for cameras these days!
