I've had an older version (3.1.1) run for over 60 days and I ended it because of rerouting some cables, not because it crashed.

Is everything working OK?  My stats page shows no blocks found for the last six shifts so nothing earned for a while now, just making sure this is correct.

My issue was that I took one of my units/workers offline this morning to swap a fan and left the other one running.  The one I left running has been fine but I couldn't reconnect the one I swapped the fan on for a few hours and even then I could connect back using the eu address but not the USA one.  So it makes sense for what you are describing. They are both back working for me now.

I also could use the backup address

Got it working on the E7440, it was as easy as disabling USB3 in the BIOS.

So... I pulled out a E6420, which is the first Latitude with USB3, but in device manager the USB root hubs were not listed quite like the 6430u and E7440 so I tried it.  It worked as instructed, I plugged in the BFL, let it install the drivers, ran zadig, changed it to winusb, restarted and cgminer recognizes it.  I ran the java API stats and found out my unit has two processors with only 11 engines working on each with a theoretical max of 6072 and already has been hashing at 6GH/s overnight with bfgminer so that lets me know not to worry about getting a AVR Dragon to change anything...

I'm going to mess around and see if I can do anything to kill off the USB3 on the E7440 and get the winusb to work in cgminer, so any advice or experience is still appreciated and any pros and cons of cgminer over bfgminer is welcome also as I want to run the one that's going to give me the best results with 18 BE and this BFL 5GH/s attached.  And I still haven't decided whether I want to run the 18 BEs in one instance and the BFL in another and have two workers where I can stop one without the other and count their stats independently or just run them all together in one miner instance and have one worker with everything combined.  

Oh no, the computers are Dell 6430u and two E7440, only have USB3 ports and are super low power consumption compared to what I have that's USB 2.  So I wonder if I could uninstall the USB3 chipset drivers or somehow disable USB3 and get it to work, or is it more down to the hardware level?

This E7440 only uses 5w when the display isn't lit (compared to a E6410 at 18w that's running 18 block erupters) and I'd really like to use it for the BFL and 18 block erupters.  I'm using cgminer 3.1.1 on that 6410 with USB3 hubs (it's a USB2 computer) using the //com/ switches but like I said I'd love to move over to the 7440.  Is there a version of cgminer that will run the BFL and BEs using the com ports?  (Or better yet if I could kill USB3 on the 7440 and make the winusb way work with a new version)


And finally, I know you are the one behind cgminer so what are the reasons I want to be running it vs bfgminer?  I've read something about it using less CPU to do the same hashing so if that's true will that save me power and what are any other advantages?

I've plugged, unplugged, booted, rebooted on three different computers and it does show up correctly on all of them but cgminer just says it's waiting for hotplug devices.  I can post screen shots later of all the steps I take, how it shows up, etc.  

I can also choose uninstall from device manager, let it get redetected by windows and it gets a Com port assigned again and goes back to working in bfgminer.

I do IT work for a living but not afraid to admit I am most likely missing something obvious, haha.

Bump for help, or should this be moved to the Mining Software forum?

I just got my 5Gh/s miner today and using Win 7 64bit I was able to plug it in, it installed itself automatically (on a Com port) and I could start mining just fine with bfgminer.  

I want to use cgminer (mainly to use the java API stats to see what my unit looks like) and followed everything I can find on using zadig to replace the drivers with the winusb drivers but every version of cgminer I've tried says "No USB devices detected.  Waiting for USB hotplug devices or press q to quit".  It shows up in device manager as a USB device as BitFORCE SHA256 SC and everything there looks textbook from what I've read.

I've actually moved through 3 different laptops with Win 7 64bit on them and they do the same, first time I plug it up it works fine with bfgminer, I replace the drivers with zadig and then it's nothing after that with either bfgminer or cgminer.  What am I missing here?

It will only do bitcoin and things that use sha256 only. For the next ~10 days it will make .004 btc per day and then less after that.  That being said I ordered one months and months ago when it would have paid of itself in less than a month but still waiting for the order to be filled.  

I've seen a couple things about doing it on a Synology, buts that's all.

I call this the hash cart.  I've got three more BEs and another small Anker coming and then I'll probably move all of it into the larger enclosure that I made in the last picture, with a set of fans closing in each end.

Haven't paid attention to the total rate of the pool during the slowdowns but this morning it was already slow when I woke up (only making .0011 per hour instead of the .0015 I can get with 5G and this 65Mil difficulty) so I switched over to BTC guild for the day and every time I've checked in its shown 5000-5100MH/s and the number of shares and earnings back up these numbers. 

I'm going to switch it back to 50btc and see what it does. 

Like right now cgminer says 5025MH/s and the dashboard on 50btc says my 60 minute average is 4119 with 3452 shares earned in the last 60 min.  I know how they say to go by the miner app speed but if I really was doing 5GH/s my 60 min shares would be between 4100-4200.  So it seems like something's getting lost between me and them. 

I've got 15 block erupters running in one instance of cgminer that for weeks has held a pretty solid 4900-5050MH/s rate into 50btc, doing about 4200 shares an hour.  My Internet bandwidth is 30/2Mbit advertised and seems to live up to those numbers.  

So just the last two days during the ~ 7am - 7pm time frame my reported speed in the pool shows to slow down to the 4600MH/s range (cgminer still shows 5GH/s) but my 60 minute earned share average is definitely falling.  I know how the pools say to base hash speed off the miner stats and not the pool reported speed, but I'm only getting in around 3600 earned shares at these times.  

I do have a difficulty of 1 set but never experienced bandwidth/pool connection problems in the past.  Should I attribute this to needing to up my difficulty level?  Since my speed came back up to 5GH/s last night but has fallen again by almost 1G first thing that comes to mind is packet loss or connectivity problems on my end but I just remoted into a server I have running at home (from work) and everything seems fine with my connection.  

So is the consensus going to be that I need to up my difficulty setting in order to cut back the traffic and see how it goes from there?
 

Got mine, thanks so much!

I finally got my btcquick account verified and now they are out of BTC to sell :-(((

Waiting on btcquick to approve my membership so I can buy BTC, been 24hrs so far grrrrr.
