Hello
I bought for curiosity and test antminer u3 and raspberry pi3 installation as per the instructions from several sites and and nothing cgminer works but does not see usb devices. QUESTION how to bite
I bought 3 U3's, 2 of them died within a few months.
I tried different power supplies, it did not help.
Theose two devices are detected by Linux as being UART controllers, but the software (cgminer) gives usb_init errors.
The third device works well.. still does.
Any ideas what to do for those two?
Thanks!

Personally. I wouldn't buy one as Sidehack is just about to release a BM1384 miner with better efficiency and hashrate in a pod form, but good luck with your miner; the connectivity issue is way bigger than it seems on paper. That's what deterred me from buying one.
Thanks allot for the update. I was just wondering if another version of the Antminer U3 wouldn't come out soon, since the only way of buying one seems to be second hand from Germany. Do have any idea of when the new BM1384 will be released?

Hi guys.
I know this is an OLD topic, but I just wanted to give some major props to Dogie and a bit to Mikestang to, for being excellent with helping new guys setting up their mineres. You guys rock.
I'm thinking about purchasing my own U3, and joining the ranks as a miner, but I'm probably only gonna go with one as long as the connectivity issue with multiple U3's persist.
Thanks for the great read and info.

Anyone know the dimensions, or maybe a McMaster-Carr part number for the screws that mount the heatsink to the U3? I have the newer version with the wire cage. This would be the screws that have the springs on them I'm referring to.
Thanks!
Thanks!
I got a brand new U3 straight from Bitmain over amazon. Have been fiddling with it all night and can't seem to get it recognized by CGminer. I have done all the steps and don't know what else to do? Any ideas would be helpful.
My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385)
I downloaded CGMiner 4.9.0 and made a notepad file with this in it...
cgminer.exe -o us1.ghash.io:3333 -u DebitMe.U3 -p 123
and saved it as a .bat file in the cgminer folder.
My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller"
When I start CGMiner it says "No Devices Detected"
What am I missing? It seems to be recognized by my computer, but just not by CGMiner.

Maybe start CGminer THEN plug the USB in
That's how CGminer worked for the little gridseeds,at least for me
Yeah that's one option, apparently hotplug has a better chance of detecting devices. Are you plugged in via USB 1.1, 2.0 or 3.0? Are you putting it through a hub at all?
Ok, I can try that when I get home. I have tried it on my main desktop through USB 3.0 and 2.0, then on my little netbook that I used to run all of the AsicMiner USB devices, which should be 2.0. I am not using it through a hub, I can try that too as well though.
The notepad doc you you have -o us1.ghash.io:3333 -u DebitMe.U3 -p 123, i take it these details are yours, do i need to tp register some where to get my oun details to add to my .dat doc?
Yes, on a pool like antpool.com, ghash.io etc. Make an account, change the "-o" string to that site's mining servers and the "-u" string to your username.minername. "-p" doesnt matter so 123 is fine.

Hi Debitme
I think i have done all the bits in the set up , my question is in relation to the note pad txt doc need those details where do i get them , i see part of the info in the doc has DEBITMe in it i take it those are your details , how do i get my own details to fill in ?i take it those detail are how you are identified to be paid for the work you miner does?
Cheers

There was a known bug with 4.9.1 that it would not recognize the U3. You should be using the latest release, v4.9.2, it was fixed for the U3: http://ck.kolivas.org/apps/cgminer/
I'm trying to get my Antminer U3 setup. I've done all the correct steps with Zadig, but for some reason, when I try to run CGminer, it says
"No devices detected! waiting for USB hotplug devices" "Probing for an alive pool" " Pool 0 difficulty changed to 256" " Network diff set to 72.7G" " Pool 0 difficulty changed to 51" "Stratum from pool 0 requested work restart"
I'm on Win8.1 running CGminer 4.9.1
This is what my bat file looks like : cgminer.exe -o stratum+tcp://stratum.bitcoin.cz:3333 -u foxtwofive.worker1 -p 123
Edit: I tried running on cgminer 4.9.0 and i get the same messages.
Edit 2: Got it working had to close bitcoin wallet that was running, solved the problem.

Exactly which version of cgminer are you using?

Try something like cgminer.exe --bmsc-options 115200:0.57 -o stratum+tcp://mint.bitminter.com:3333 -u --bmsc-voltage 0800 --bmsc-freq 1286

is there a cgminer for Mac OS ? I would like to connect a u3 to a Mac Mini.
See unofficial compilations here.

If it runs satisfactory to you in stock setting leave it like that.
800v 250freq is considered pushing the machine pretty hard, although some folk run as high as 830v.
When I ran mine I used about 785v 237.5freq.
Get yourself an extra fan on the bottom of the unit if you're going to OC, they get hot.

What are the best settings for the U3 without really taxing the unit? I am just running it without any settings other than stratum - user- and password.
Thanx guys!
Thanx guys!
It mite be that my windows xp does not have enough resources to run two antminers at once. Its a old machine.
Mine is old, too, and still runs XP, so yea, I think that has something to do with it.
Read through the other thread you posted in and follow my trail, I tried several different things to get 2 to work together and never had any luck. You could try the same things, but chances are you'll just be wasting your time. Do you have 2 computers to each run one?
Hi.
Yes I do have two computers. But the idea was to have one for mining, also less electricity. But I left one on each running.
I'll give it a try with a linux machine and see what happens.

I needed to set my bat file to:
cgminer.exe -o solo.antpool.com:3333 -u userid_X -p 123
Instead of
cgminer.exe -o stratum.antpool.com:3333 -u userid_X -p 123
I was wondering what is the difference?
They should both work, AntPool has many servers with different names and port numbers. That is unless something has changed recently and that address has stopped.cgminer.exe -o solo.antpool.com:3333 -u userid_X -p 123
Instead of
cgminer.exe -o stratum.antpool.com:3333 -u userid_X -p 123
I was wondering what is the difference?
I'm not looking to overclock but I'm guessing this command is for that purpose right or something else?
It depends what (and who's) version of cgminer you're running. If what you have works then stick with it.Hi Thank you.
I will stick to my current configuration then. But I'm running cgminer 4.9.2
I was busy opening a new thread, but maybe you can help me has I can not find a fix, only people complaining of the same.
How do I connect two Antminer U3 on the same computer?
I tested then separately first to make sure each one is working. I confirmed that, and no errors. All working fine.
When I connect both antminers I start getting error:

Hi,
Got my very first antminer U3 miner today
I got it working fine and easy thanks to this great guide, Thank you.
I did need to do something different for it to work.

Has pointed out in this thread.
I was wondering what is the difference?
Also while searching around for solutions I found some posts that have added parameters to the command line.
In fact, one of the sources I found was antpool page:
https://www.antpool.com/support.htm#help_2_3
They provide this example:
cgminer.exe --bmsc-options 115200:0.6 -o solo.antpool.com:3333 -u antminer_1 -p 123 --bmsc-voltage 0800 --bmsc-freq

don't use cgminer and zadig driver ... is a solution.

clean the zadig install : http://www.smallbulb.net/2013/287-detaching-ms-windows-libusb-driver
install a "COM" virtual port (yes, a old and very strong serial port)
install BFGminer

will this run on a computer that is running a scrypt fury? Cant get it to work on that computer.
I cleaned up the factory thermal paste application and reapplied it correctly on all 3 of my U3s. It made a little difference, each one runs 1-2gh faster than before when run solo, which I can attribute to better heat dissipation. But it made absolutely no difference (as I expected) in more than one working when plugged in at the same time.
So now I think I've tried everything. Anyone else have any ideas?

The last thing now is to try a different computer or host to see if you can wittle the problem down to controller or U3s.
I've tried on two computers, I guess I could try on others. The two I use are both kinda old and Run WinXP SP3, so maybe I need to try a current machine/OS combo and see if that makes a difference.
I feel like a crazy person that I can't get more than one to work. I can read through threads and see that it is possible, but I just can't seem to find a break.

Installed cgminer 4.9 instead of the newest one and it works now.
Yup, I pointed that out in a couple other U3 threads, I think in the official cgminer thread, too. cgminer 4.9.1 will not see U3s, but 4.9.0 will. Send in your bug report, hopefully it can get picked up next build.

USB hub received, I hooked it up to my power supply, plugged in one U3 and it worked just fine. Plugged in the second and ERROR. Quit and restarted with them both plugged, more ERROR. They both hash together at about 30gh each (down from 59 alone), but with constants errors as below. So what else could it be? (I unplugged one USB toward the bottom, I think that's what the last 3 lines are starting to show)
Is that a powered USB hub?
Yes, 12V DC off my computer psu.

Just ordered the mother of all usb hubs, if they don't work with this then the hub ain't the problem:

That's definitely using MTT chip
Get the power from your 850 psu will be perfect
Do you know if 1 pair of yellow/black from pci-e will be enough? Two pair? Says it needs between 7v-26v DC. Thanks.
Yes, 1 pair should be enough.

These miners seem really interesting. Thanks for posting this setup guide also. I remember the U1, and they came a far way in terms of hashing power.

Some how it's hard to know unless you open the hub & check the chips type.
Or you can mail the manufacturer about the chip.
And do not used the original dc supply. Get the power from your PSU.
I will research, thanks.
Yes, I have them running off a 850w psu with an S1, thanks.
I mean get the power for the usb hub from 850w psu too
Why would that make a difference?
Depends on the exact USB hub, some come with pretty lame power bricks.

Check you powered usb hub chip. Is it STT or MTT chips?
You need usb hub with MTT chip.

How would I go about doing that please? It's an Ensignia brand from BestBuy, model number NS-PCH5421, 4-port USB 2.0 hub. 5vD.C. ~100mA, thank you.
I've had great success running one of these units. I have it on a powered USB 2.0 hub and use a molex 4-pin to barrel plug of the 850w psu my S1 uses. Using cgminer 4.90, 775v 237.50mhz gives me a super stable ~57.5gh.
Did you ever try getting more than one running at the same time? I bought two more U3s, but I can't get more than one of them to run at the same time; any of the 3 run fine by themself. Using stock volt/freq for all of this, I've tried launching cgminer with 2 plugged in at the same time and I get constant LIBUSB from both devices. If I unplug one the other runs just fine. If I launch cgminer with just one running it hums along perfectly, then I'll hotplug the second one in and instantly the LIBUSB errors start. I've tried with them both plugged into my powered USB 2.0 hub, and tried with one in the hub and the other in a separate USB port on my computer, but no matter what if more than 1 is plugged in I get LIBUSB errors. Any ideas?

Check you powered usb hub chip. Is it STT or MTT chips?

I got a brand new U3 straight from Bitmain over amazon. Have been fiddling with it all night and can't seem to get it recognized by CGminer. I have done all the steps and don't know what else to do? Any ideas would be helpful.
My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385)
I downloaded CGMiner 4.9.0 and made a notepad file with this in it...
cgminer.exe -o us1.ghash.io:3333 -u DebitMe.U3 -p 123
and saved it as a .bat file in the cgminer folder.
My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller"
When I start CGMiner it says "No Devices Detected"
What am I missing? It seems to be recognized by my computer, but just not by CGMiner.

Maybe start CGminer THEN plug the USB in
That's how CGminer worked for the little gridseeds,at least for me
Yeah that's one option, apparently hotplug has a better chance of detecting devices. Are you plugged in via USB 1.1, 2.0 or 3.0? Are you putting it through a hub at all?
Ok, I can try that when I get home. I have tried it on my main desktop through USB 3.0 and 2.0, then on my little netbook that I used to run all of the AsicMiner USB devices, which should be 2.0. I am not using it through a hub, I can try that too as well though.
Don't use USB 3, it uses different drivers / something else that usually prevents it from working. Powered hub can help with dropout issues as there is a reasonable amount of 5V load.

So how quiet are these miners? (can not find any video with this miner) im only after quiet miners. i did see that Bitmain came out with a new design on them.
It looks to be exactly the same fan, so it then depends on what your definition of 'silent' is. To me they're as quiet as ambient, but its personal opinion.

after some tinkering i got minera to work with some ease. Minepeon is to outdated to work with the U3 out of the box for anyone else looking to run these on a pi go with Minera and change from default of CPU miner to CGMINER on the latest version 4.0.0 works with only those changes
Any good recommendations for a raspberry pi based controller that supports the U3?
Raspian, Minera, MinePeon, anything that will get you cgminer.
I am familiar with minera for Gridseed devices but was unable to get it to detect the U3 I was offering this as a suggestion for a future guide from you if you had time to put together a setup guide for Running the U3 off of the Pi to expand off this setup guide. I have also tinkered with Minera but the latest build has an outdated cgminer and wont detect the U3 and the bfgminer works but only hashes at 4GH. I am still tinkering but no clean off the shelf solution to run a Pi with the U3 yet without some tinkering
I still go for Raspian because its essentially just a linux environment, so you can put whatever cgminer you want on it. There are obscenely long instructions for that in the Noncetech guide if you want to go from scratch, although other users may be able to provide nearly complete SD card images for Raspbian.

I think the only other thing to try would have been something like a long nylon cleaning brush from an electric razor dipped in alcohol. Still tricky though.
[Slight necro, was accumulating U3 feedback from all the threads]. That's a good point, I'll find some micro brushes to buy. Can douse them in articlean and work out the paste.
Annndddd...bookmarked. I just purchased an Antminer U3 to test the waters, this guide is comprehensive and easy to understand. I wish I could tip you.
You can, but its not required by any means!

Is Bitmain still applying thermal paste with a pneumatic butter knife?
They're usually very good with thermal paste, if you see S1-S4 chip pics, they spend the time to paint each chip individually. I'm not sure what happened on this one, but it was impossible to clean with all the resistors so close. Was either going to be goop or cloth fibres, and the goop was there first.

0a) What to Expect (top)
Bitmain's Antminer combines four BM1382 chips into a small package. Noise levels are extremely quiet and so can life on desktops and be given as gifts. A
USB cable and power supply is provided in the package, although you will need a power cable and external controller to get started.
0b) What You Need (top)
In addition to a host windows PC, you will need some accessories to get started.
Click your flag to find everything you need to get started at Amazon!
1) Powering (top)
U3's come with a 2.5mm 6A 12V mains power adapter, although you will still need a mains power cable.
2) Cooling (top)
The U3 is self sufficient in cooling terms and is self sufficient in cooling terms and utilises an aluminium finned heatsink on the top of the chips. A 92mm fan
provides ample but silent airflow through the heatsink and over the board. The backside of the PCB is screwed to a blue aluminium plate, which acts as a
heatsink and the base of the case.
3) Configuration (top)
U3s can be run on any CGMiner based device. A Windows based PC is recommended although a similar process can be applied on a Raspberry Pi.
