It seems that you are using only one chip instead of five. Try official not modified mining software and cgminer may be

additional it gives around 30Kh

Hey guys!

Yesterday I have bought d-link hub-h7. I have two 5-chip gridseeds and two antminers u2. I tried to run this antminers in charging ports, but it can handle only one at a time (as soon as I found this topic and see that yes, only 6 devices).

But I was able to run them both on that ports. All I need to do is manualy reconnect usb cable in rpi. I have tried to programmatically restart usb ports, but have no result. May be someone found a decision?

Don't what that parameter means , but when I set to zero (btc=0) cgminer only rises LW value and not sending accepted shares. 23Gh avg.
When I set to btc=1, It began to hash at 16Gh avg with some sending shares, but LW is increasing anyway.

May be the problem in usb hub? It has 2A in. The power supply for each gridseed is as usual 12v 5a.

Don't know what should I try yet.

Hey guys!

I have two 5-chip gridseeds. I was minig scrypt long time via RPi, but now i want to mine sha256. So, here is my trouble. cgminer (gridseed version) is minig at a half speed (~5Gh per device) with 800Mh clock. What  I'm doing wrong?

The run command is standard: ./cgminer --gridseed-options=baud=115200,freq=800,chips=5,modules=1,usefifo=0,btc=16 --hotplug=0 -o someurl -u someuser -p somepass

P.S.: all minerd and other cgminer (for my ants) threads are shut off.

0.00075+-
and decrease this value on 0.00015 for maintenance fee

My 1Mh hashlet gave me ~0.004 for the week of work

I have just asked about it. This is a 8 Gb USB flash drive + LTC miner with the software inside. I asked about the software to use with.

It seems that it only will work with Windows

I love that company! Preordered a fury and some time later I came out of money, so till 2 hours of the batch shipping Amanda cancelled and refunded my order. Very nice support, but I knocked to them almost a day.

Hey guys!

PLEASE! DON'T MINE KARM ON multi-pool.eu!!!

It uses scrypt, but now it's x11. I've mined 2 days, because http://cointweak.com/calculator/index/scrypt says me about a great profit on this coin, but it X11! Be aware of that pool till it updates.

So, the point of the last sentences in this thread are that, as I said earlier, you should invest in 20-50 last-hash miners to ROI. Or in the best ways you can get 50% ROI instead. No matter what cost of power you have, stupid TH that will drive you as a Russian tank to your ROI.

But we all know that a medal has two sides. On the other side you could get only 50% ROI in a very very very good case. Even if you are going to sell them on ebay.

Mining is a such complecated game like chess, where on one hand are the ASIC (now ASIC yes, not GPU) manufacters (who are mining for the full mf power in their plants) and on the other are your strategy how to buy cheap (BTC or ASIC, no matter) and sell with some expensive interest.

Btw, I'm watching for the interesting cheap proposals miners in ebay and ali almost every day. Yeah, I'm a quite low now in a budget, but I can afford to buy some "hexes" 30Gh+ for 50-60$ + 15-20 delivery costs. Why??? I'm never ROI with them, because the delivery is so long to Russia from US, but I'm funky loving that small machines. May be I can buy a full computer instead to mine X11, X13 or even Scryot-N?.. Why not? Credit organisations will make their ROI faster ha-ha I'd love too, but I have a free power cord in my room, I'm not interested in computer! I like these machines which are blinking with ssh access leds power-cord-webs.

So, everyone chooses what his heart whants this time. But brain understands that this is wrong. That's like smoking may be...

So, let there be punk-rock and BTC! Oi!

That's a good idea! We need just another 14 Ocean's friends   and... Salma Hayek, e.g., to distract the guards  
Why 14? But who then will carry out all the miners from the data center lol

My two cents in your conversation, guys. I've bought a single 5-chip gridseed in 04.2014 for 200 bucks. All I earned is 0.1 BTC. My thoughts are: if you wishh to get your ROI you should invest 5-10k $. But as for the small miners, you will never ROI.

But the mining hardware, when it's working is pretty funny as usb antminers "when fun > ROI"

About ASICs. Somenone told here in a forum that an ASIC is more profitable then a simple car. If BTC is your hobby and you can use the city transport, then you can buy ASIC instead of a car. Such a comparison I heard here... Don't know if it's a tottaly true, but there is something abount to think...

Hey! I have the following setup: two 5-chip Gridseeds, one USB U2 Antminer (the second is coming soon), the 7 port USB 2.0 hub and a Raspberry of course.

I'm not using such distros, but using the default Raspbian. For me I find the following way which is working well with my setup.

At startup I'm starting two minerd miners (each for the one of the gridseeds) and one cgminer. Cgminer crashes some times and minerd rarely, but freezes. So, I have a cron script to check cgminer running or not and an every hour reboot script.

Sometimes, because it's hot now and a superfarm is standing in front of window, the Raspberry freezes, so I mannualy reboot all "the systems" with one power switch

You can put it in oil, but what will cool the oil???

Amazon replies are so replies... When it was not hashing it was not lightning steadly.

Hey guys!

I'm using that small bastard a month or so already. But only now I saw that it was lightning constantly with upper green light, not the bottom one, which is flashing when if finds a share. What does that mean?

Here's the image

Hey guys! I can not find the proper command line to start mining. I was trying the cgminer with no results (no devices found). Now, the bfgminer. My cmd is following:

Have tried different variations and I've got nothing. But! If I run only
and then manually adding the device in program it start mining, but at speed near 250 Mhash.

RPi runs raspbian, accessing via SSH. Antminer connected directly, because I want to make it work before installing the hub.

P.S.: cgminer and bfgminer were compiled from sources, the latest versions.

Wow! The coin comes from death!  Why? Did I miss something? Will begin mine it now anyway.
