ANTMINER U3 Discussion and Support Thread

[dogie]

I have 2 U3's it running on my PC, getting 60+ with a PC PSU, want to move it to a Pi so I can run it 24/7.
Occasional zombie's, but it seems to happen on my slow ION system, but not on my i7 system, probably some USB timing problem.

What RaspberryPi OS-all-in-one-miner-monitor would you recommend for the U3?

Any of them, MinePeon, Minera etc.

Ok, thx, trying out Minera.
Any quick hints on how to update cgminer to the latest version when using Minera?

[ImCrazyOne]

ImCrazyOne  nice idea about connecting miner to PC directly.
A simple molex, I like it (sent a tip   )
Much better than the board - to 6 pin - to barrel I had set up.

Yes its very convinient, i have one miner sitting in every computer in my house even the HTPC that is connected to TV. So when i watch a movie or just use computer i know that i am also mining bitcoins. CGwatcher is a great tool to have it automate everything. Thank you for the tip kcal63.

Why anyone would want a USB miner these days is beyond me.

I just got an Antminer U3

I have it all hooked up, installed the driver just like this states

SETUP INSTRUCTIONS
1. Install driver
2. Plug power brick into AntMiner U3 before plugging power brick into wall
3. Plug power brick into wall
4. Connect USB cable from AntMiner U3 to computer
5. Open Zadig and click "Options -> List All Devices"
6. Select CP2102 USB to UART Bridge Controller, and then click "Install Driver"
7. Run cgminer with the following parameters (remember to replace "-o XXX -u XXX -p XXX" with your own information):

cgminer.exe --bmsc-options 115200:0.65 -o XXX -u XXX -p XXX --bmsc-voltage 0800 --bmsc-freq 1306

When I run the miner, it says "Bitmain Detect failed to initialize -- Incorrect Device?"


What am I doing wrong?

Any other USB miners on the system? What type of USB port are you using (2.0/3.0 etc)? Are you using a powered USB hub?

[darkstarwars]

USB 2.0 .. No Hubs.

[dogie]

USB 2.0 .. No Hubs.

Please put the U3 on a powered USB hub, as there is quite a bit of draw from the USB interface.

[darkstarwars]

Ok let me go get one, and I will be back in about 60 mins.

[darkstarwars]

Ok, Im back. All hooked up..

Now how do I get this running?

Can you take me a screenshot please?

[darkstarwars]

I think I have it going..

Its showing all the stats running now, the 5 second ghs, 1m GH/s etc.

Now, on the antpool my workers are inactive... Do I have to wait any amount of time before they start showing as active?

Well it was working, then it said ZOMBIE now its showing failed to initialize

Which software are you running? You can find the latest versions here: https://bitcointalk.org/index.php?topic=879732#post_section3

Antpool is quite slow to update.

[darkstarwars]

I am running

CGMINER 4.8.0

ZADIG 2.1.1

[darkstarwars]

How long does it take to see your first payment/reward?

How long does it take to see your first payment/reward?

Quite a while, some hours.

[vayvanne]

any plans to continue this form factor of miners with newest chip BM1384?
and wish with wireless connectivity

[darkstarwars]

When I run my miner, it only mines for a brief amount of time then shows ZOMBIE

[darkstarwars]

I dont want to send anything back , unless you think its broken

What does Zombie mean? does it mean its broken and cant be fixed? Is there anything I can do to ensure that it stays mining and not saying ZOMBIE ?

I have an antminer u3
7 port Powered USB HUB, with AC adapter
ZADIG 2.1.1
CGMINER 4.8.0
