I have looked over google for some help but im obviously not looking in the correct places because I did not see what i need. Hopefully someone here can point me in the right direction. Here is whats going on. I started off with 1 asic block erupter (ASICMiner Block Erupter USB 330MH/s Sapphire Miner) and everything was going fine. i added another one to the setup and everything was still going fine. (this is all being done on USB ports that are on the back of my PC, no USB hub, yet) I then aquired an antminer (BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner. Overclockable) and plugged it into my PC as well. I am using BFGminer 3.10.0 currently and everything was running fine. all 3 miners were mining. I went ahead and ordered a usb hub because i figured if i was going to keep adding miners that my computer would not be a good place to put them all. well a day before the hub got here, i noticed that one of the miners (the saphire one) was not mining. i looked at my device manager and only saw 2 of them. so i rebooted, messed around with some different ports but nothing made that one work. i figured it was broken for whatever reason and assumed it was because it wasnt suppose to be on my mother board. thing is, it works on another PC. so i waited for the hub to come in to see if it would work on there but it still does not. Im thinking its a driver issue since its not showing up on this computer but it will on another. Any idea or suggestion on how to get my current PC (windows 8.0) to run it? Should i try a different version of bfgminer, or maybe cgminer? im fairly new to all this so i dont really know where to go with it.
Hello everyone! I'm looking into getting into mining scrypt currencies like Litecoin and ran into some vary weird calculations that just can not be accurate, but I'm not sure what could be wrong. I found this miner: http://www.amazon.com/BITMAIN-ANTMINER-U2-Bitcoin-Overclockable/dp/B00ITD5NV6/ref=cm_cr_pr_product_top It claims to do 2 GH/s which seems crazy as it is. So I was curious about how profitable it would be. So I Googled "Litecoin mining calculator". I found this website: http://litecoinminingcalculator.com/. It asks for kh/s for their calculator. So I enter in what the 2GH/s would be and unless my math is wrong it should be 2,000,000 KH/s. At that rate it estimates I will mine 191.25 Litecoin a day at the current difficulty of 10,307.9291509 (could this be wrong?) At 191.25 LTC a day that is 67415.09 LTC a year. That has to be wrong isn't it? That's absolutely absurd number. Something has to be wrong, but I'm not sure what it is. Any ideas?
Really want to buy a miner and get started mining for fun. I'm stumped, however, because there are Ghashes, Khashes, and Thashes. Is this miner worth the initial investment? And if so what hash rate could I achieve relative to Doge coin?
I am just starting doing this as a hobby and need some help.
So I bought a BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner, and downloaded BFGminer and that is as far as I could figure out what I have to do. So I was just curious what are next steps I have to take to get mining. Thank you in advance.
Hey guys, I was interested in purchasing a Bitmain Antminer U2 off ebay. I've been pool mining alt coins with my HP Pavillion core i3 2.8ghz computer but obviously am not getting lots of shares unless they are new/easy mineable coins. Do you guys think I should purchase a U2 as a beginner? I'm not planning on mining bitcoin because of the difficulty, but mostly plan on pointing to new sha/scrypt coins and try and make some btc selling them on exchanges. Any advice for a semi-noob? Is it easy to set-up? I've read that I need a powered USB hub? and I've also seen some people having problems setting up their U2 miner? Any one have experience using one? Would love to use this as a way to learn more, mine, and maybe move onto a decent upgrade/rig in the future. Any input would be great, thanks!
can a BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner be used to mine Doge? I know Doge and Litecoint are SCRYPT while BitCoin and others are SHA-256. I can seem to find what the difference between this miner and a dualminer which claims to mine both... any help understanding this is much appreciated
Hello everyone, I just recently bought an Antminer U2. I have attempted to try and mine using it however I am running into some problems.

Uncle Bubs is selling three Antminer U2s. These are USB sticks that mine sha256 currencies at 2.0GHs (manufacturer recommended, although I run them at 2.2GHs with no problem), using almost no power (2 watts). Included when you buy from me is a quick start kit, including BFGminer preconfigured to work with your Antminer, the device drivers, and a tutorial on how to start mining. All of my miners have been tested to verify they work and overclock properly. Antminers can be seen on Amazon here for $27.50; I’m selling mine for $20 plus $1.99 shipping, or free shipping if you buy all three. The price is the Coinbase price in USD at the time of sale. Ships to the United States only. Uncle Bubs accepts Bitcoin as payment; contact me at [email protected]. Or, if you’re more comfortable with credit card transactions, you can buy them at my Ebay auction. Note that, while you may see some on Ebay for around $14, those are auctions. Having tried and failed many times to buy something from an Ebay auction only to be outbid at the last second (literally the last second), I only use “Buy it Now” now. Antminers will mine any sha256 currency, including (but not limited to):
What is Mining? Introduction. Mining is the process of adding transaction records to Bitcoin’s public ledger of past transactions.This ledger of past transactions is called the blockchain as it is a chain of blocks.The blockchain serves to confirm transactions to the rest of the network as having taken place.

The Antminer S9i follows the same form factor as that of the hugely popular Antminer S7 and is nearly the same size. Yet it has more than thrice the power and twice the efficiency of the S7. Each Antminer S9i employs 189 such chips to deliver more hashrate and efficiency than any bitcoin miner ever made. I've recently received an Antminer U2 and have been having trouble trying to get it mining. I'm using bfgminer 3.10 and can't get it to hash at all. I'm using a hub with sufficient power (5v 3.5a) and also have two block erupters that are mining without issue. I've tried just mining with the Antminer, but bfgminer doesn't see it. This antminer works fine but, my self and others do seem to have to overclock it to get the 2gh/s. with cgminer 4.3.3 I set it at--anu-freq 280 which runs it about 2.2gh/s per ASIC miner. That setting keeps me at about 4.450gh/s which varies from time to time but still a steady average of 4gh/s (two U2 miners).
