EDIT - Solved.

Removed WinUSB, installed the default serial drivers and used BFGMiner.

Thanks to all that tried to help!

G'day All,

I'm having a bit of a technical issue, and I'd appreciate your thoughts.

I'm trying to use CGMiner v3.9.0 with an AMU on a Windows 7 64bit machine. Everything seems fine on the hardware side of things - I can start CGMiner in benchmark mode and see the device hashing away happily.

This is the string I'm using to try and connect:

cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u [username].[workername] -p [workerpassword]

When I try to run cgminer and connect to the pool, I get an error as follows (debug output trimmed - let me know if the untrimmed output would assist):

As a matter of interest I've also tried connecting to BitMinter with the same result, and I'm not running a firewall.

I'm going quietly nuts trying to get this thing to work, and any assistance at all would be much appreciated!

I am mining here for more then half year. One day we have a luck (15 block founded) one day not (3-5 block founded). At the end it is all about luck. Wait and watch your average earning for week or month. I always get best results with this pool. Other pools don't give me this earning like here.

For what? A specific shift? I see nothing but confirmations with no invalids...

Those rental contacts are absurd. $120 for an hour at 60 Gh/s which equates to maybe, just maybe $9 worth of bitcoin. Just craziness... And people pay it!

I've literally just gotten it working!

Apparently the WinUSB drivers that I installed using Zadig were not playing well.

I uninstalled the WinUSB drivers and installed the standard serial driver (Silicon Labs CP210x USB to UART Bridge), tried BFGMiner instead of CGMiner, and all of a sudden I'm picking up the pool and hashing happily.

Many thanks for your interest and for trying to help!

No but 21310 I got 0 for some reason. The pool has been strange lately and I am considering joining Eligius.

same issue with confirmed stuck

i open ticket on site , hope they will fix it like previous problems soon

Are people getting reward payouts, if the confirmations are 'stuck'?
I'll probably move my miners somewhere else, until the 'fog clears'....

I use this-- http://www.alloscomp.com/bitcoin/calculator when speculating about hardware, I know it's falls rapidly out of date for future difficulty rises, but it gives me an idea of what a miner can do, immediately. What I want to know, is does anyone have a link to any mining calculator that might give me some ideas on solo mining? Like one that will say how many days/weeks you could expect a block for with a given hashrate? Does that make sense? Basically, a solo mining calculator. I'm not really planning on trying solo, but it would be interesting to know.

thanks.
