The power supply itself should be fine, I was just indicating that troubleshooting the quality of your connection to the tecnobit miner would be a good place to start.

Also, you can try to plug in the device's USB cable to the router/computer only after cgminer has fully started.  That makes a difference for me.

Sometimes the power supply is not properly connected to your device.  If it is the 4 pin molar connector type, sometimes you can get it to start after unplugging the connector and reinserting it to make sure you have the plug firmly connected.  If it is the two screw wire connection type, then you have some extra work to do in order to make sure that you have a good electrical connection.  Use the proper gauge of wire to ensure a snug fit.  I use the power from the PCI-e power supply connector.  You must observe the pin-out diagrams of the PCI-e connector:  



Ground is on the clip side of the connector, and +12 v is on the side without the clip.  The connection to the miner 2 pin screw terminal is red (+12 v) to the right terminal (the outer edge of the circuit board) and the black wire (ground) in the left screw terminal (pointing in the direction of the fan).

The tricky part for the power supply  when using the PCI-e connector is making a reliable connection that will not be tugged out inadvertently.  Something I learned by trial and error when I would come back and notice that the miner had lost power because the wires got loose and lost connection.

The fellow who was selling these was doing brisk business for a while, however the sales have trickled to a slow crawl.  People are probably realizing that getting a full return on investment from these is not very easy.  Especially when you consider that the original price was around $200 per miner, then eventually half that price.  And the cost of electricity, like you said.  To try to compensate, I have rolled much of my bitcoin earnings from these miners back into cheaper cloud mining, to get to the point where most of the mining I do is in the cloud.

I am using a combination of Corsair CX750M and a Thermaltake smart 650w power supplies to run 6 hex16a2.  According to the Killawatt, it is taking about 257 watts to run, so that averages out to 42.5 watts.  I am running mine at 1530mhz / 1020mv.  However I was registering a much higher power consumption before when I was just using the cheapest generic power supplies I could find.  I wonder if these new power supplies are really that much more efficient, or if maybe my killawatt isn't giving me a proper reading because I have the two power supplies connected to a multi outlet adapter plug.

So far, I seem to be generating less shares with CGMiner than I was using HexMiner.   I was sometimes seeing up to 110,000 shares on certain shifts with HexMiner, but only topping at 90,000 using 6 miners.   

I got around to trying this on a different computer.  For the first time I connected all 6 miners at once and tried running this CGMINER.  Once again it failed to identify devices, although for the first time I did get it partially running.  It communicated with 2 out of 6 miners.  I was able to get about 51 GH/S, with only 2 devices recognized and running.  Then I tried disconnecting and reconnecting each USB plug individually while CGMINER was running and this seems to do the trick.   Have now finally gotten it to work with all miners running by starting with one device connected at CGMINER startup.  Then plug in each device separately, verifying as I go that each miner is getting up to speed.  Seems to work better than just jamming all the USB plugs in at once.

Voici le message que je viens d'écrire pour un autre groupe:

Pour ceux et celles qui sont branchés à la twittosphère, Jean-Philippe Gagnon donne 5 Québecoin aux 100 premières personnes qui retweetent les messages (la version française et la version anglaise):

Dites bonjour au #Quebecoin - Une monnaie numérique pour la nation Québécoise! www.qbc.io/fr https://www.bittrex.com/Market/?MarketName=BTC-QBC

Say hello to #Quebecoin - A digital currency for the Québec nation! www.qbc.io https://www.bittrex.com/Market/?MarketName=BTC-QBC

Ensuite twittez votre adresse Québecoin à JP Gagnon (@QuebecoinCrypto) pour recevoir votre récompense.

I think Telus is too mainstream to be willing to take on something like Quebecoin, which will be perceived by most of the public as something that is on the fringe.  It is best to take aim at smaller businesses, that are perhaps already using bitcoin.

In the interest of promoting the use of Quebecoin, I would like to propose a "first" test transaction.  I will offer a $25 gift card for Scores Restaurant, in exchange for payment in Quebecoin.  Upon receiving payment in Quebecoin, I will buy the gift card through the website GiftCertificates.ca, which (unfortunately) charges a $4.95 handling fee and $1 fee to send the giftpass via email.  So 30.95 CND = 28 USD = 155.5 QBC, assuming we are going by the site: http://www.cryptocoinrank.com/Quebecoin.  

It is sort of an indirect way of spending some of your Quebecoin, in the same way that some of us already do with bitcoin using the American egifter website to buy gift cards for amazon, sears, Dominos Pizza etc...

I was originally considering St Hubert's, but they only have physical gift cards.   This offer will most likely only apply to someone who lives in Quebec.  I am only going to do one of these exchanges for now.  If anyone is interested in trying this test, send me a pm and I will reply with my Quebecoin address where you can send the payment.  

I am new to Bittrex exchange and was wondering if someone could tell me what is the minimum amount of BTC needed for a BTC-QBC trade.  Then what is the minimum amount allowed for a withdrawal of QBC.

Thanks owlhooter, that was what I was looking for.  Now I have this:

It has always looked like this, upon opening the wallet, ever since I first downloaded it, and through the different fixes put out today.

I had no problem with zadig driver replacement.  Device manager lists the device properly, as in your capture.

I am new to cgminer and trying this out with one technobit HEX16A2 miner.  I have gotten up to the part of starting cgminer and getting the message that no device is detected.  I tried unplugging and restarting, but no luck.  I have opened the cgminer.conf file using Notepad++ as administrator and edited to "set_default_to_c" : true,   It is still not detecting the miner.   

Since I have never used cgminer before, I would need to familiarize myself with the program.  I followed the instructions and set it up to run one of my miners, but I am receiving the message that no devices are detected.

I am running a total of six hex16a2 miners with a windows 7 laptop.  All connected to a generic 7 port USB hub.  It did take me a while to get it configured to a point where it runs stable.  I still reboot the entire mining system once or twice a day in order to maintain stability and performance and set up the mining pool to email me whenever the miners go inactive so that I can troubleshoot it as soon as possible.  Once you figure out how to keep it stable, downtime becomes infrequent.

With this many miners I opted for 2 different power supplies.  You can run two miners from each branch of the power supply, however if you do you will find the wires get very hot.  So I set up mine in such a way as to only run one miner per branch. Proper wiring is important.  With the older boards that had 4 pin molex connectors, I found that not all 4 pin connectors fit easily.  The classic white ones were fine, but the newer black ones could be difficult to push in.  If you ran into a flakey connection, you can usually fix it by using an 4 pin molex extension cord.  You can use the SATA connectors by using a SATA to molex adapter cord.

For the newer boards that have a 2 wire power supply, I think it is a good idea to put a cable tie around the closest bolt to hold the wires in place so that your power connection cannot be tugged out by pulling on the cables.  I used the PCI-E power connector from the power supplies to power these boards, and secured the connections carefully with electrical tape.

The USB cable running to your computer should be secured to something in such a way that there in now weight on the USB cable.  A flakey USB connection seems to be a major cause of crashes.

The newest hexminer driver for Windows should download automatically.  At first I tried to manually download the drivers that were recomended by the seller, but then noticed that a newer driver was available.  Driver version 5.1.2600.7  Date: 06/12/2012  Microchip Technology, Inc.  It worked better than the older driver I tried at first.

It can be tricky to get these miners properly configured with your PC environment.  I have run into problems with Windows Firewall and various antivirus software programs trying to block or shut down the miner proxy and the Hexminer software.  Some antivirus identify Hexminer program as a trojan virus and automatically delete it from your computer.  So it is important to set up some exceptions in your internet security so that these programs will be permitted to run unhindered.  The computer you have chosen to run the miner on will be pretty much entirely dedicated mining.  If you run other programs it can interfere with mining.

Power setting in windows set to maximum, and never allowed to go in hibernation mode.  Windows updates must be set to manual, so that your computer will not suddenly reboot in the middle of the night after installing new windows updates.  These are things that will cause downtime to your mining.
