Using the latest CGminer on linux compiled from git with --enable-icarus, I use --au3-freq 250 --au3-volt 810, which gets me a stable ~63ghs, without getting more than warm to the touch.

I've had a couple of zombie moments in the last week which seem to be precipitated by pool reboots. Might be coincidental!

it looks like one of my U3 is dead:

- no hashing at all
- the red LED that used to blink when hashing is now permanently ON
- U3 is detected in windows/Linux
- windows cgminer sees it but says there's no drivers even though zadig has been installed
- linux: cgminer -n sees it, cgminer --benchmark just hangs....

I swapped power and USB cable with the same result

I'm new to mining I have just bought an Antminer U3 but can't seem to get it working it keeps saying
Probe of port com4 failed: timeout
Any help would be great
Thanks

Hello
I have Windows 10
and an Antminer u3
I have been trying with cgminer but was getting frustrated so I'm trying BitMinter neither are working

[zOU]

Bitminter doesn't support the U3

Cgminer will work just fine, but you need to install the zadig driver before, check the post I linked earlier

I used install the zadig drivers
and tried with cgminer with no luck either getting no devices detected
I don't know what i'm doing wrong

[zOU]

You're using cgminer 4.9.* ?

You can run

Cgminer -n (to list current devices)
Cgminer --benchmark (to test the device)

You can try reinstalling zadig drivers as administrator maybe.
You have the 2 solid Red LED on your U3 ?

I'm using cgminer 4.9.2 tried a few
reinstalled the drivers no difference and rebooted

tried with cgminer -n seems to see it but close window down

can only see one red led

[zOU]

Run it from a command line, not from start menu

[philspain]

Run it from a command line, not from start menu

when I run cgminer - n
this is what i get

cgminer -n

Any Ideas anyone please it is frustrating me now

[durandal]

Have you read the manual? It lists the following command (but I've edited out the pool options - see if that works, and then add the pools from inside CGMiner and then 'w'rite the config file when it's up and running):

cgminer --bmsc-options 115200:0.54 --bmsc-voltage 0830 --bmsc-freq 0982

The voltage/freq values can be modified according to the tables listed in the manual, but stick with the given ones for the moment.

Just to be sure, you are hitting the windows key, typing 'cmd' and using the command line that way?

The bsmc option has been deprecated a while ago.

Cgminer --benchmark should detect and hash at 56Ghs if the zadig driver has been installed and the device visible with cgminer -n.

Cgminer ReadMe lists the new options for the U3
(--au3-freq or something like this)

If I remember right, cgminer defaults to --au3-freq 225 and --au3-volt 775, so no need to add that in "yet".

Also I think there was a problem where cgminer 4.9.1 (or was it 4.9.0) did not work with the U3's for some, so philspain make sure you are using cgminer 4.9.2.

And lastly (anyone else that has tried), didn't Windows 10 change something, to where zagdig would not work???

[philspain]

Thank you all for your help I will try these this afternoon and get back to you.

[philspain]

this is what happens when I try cgminer --benchmark

just reading the readme it say

ANTMINER U1/U2+/U3 devices

Antminer devices need the --enable-icarus option when compiling cgminer.

Currently the U1/2/3 USB sticks are supported and come up as the following
devices:

ANU: Antminer U1/U2/U2+
AU3: Antminer U3

but it says
\cgminer>cgminer --enable-icarus
 [2015-12-21 16:22:14] cgminer: --enable-icarus: unrecognized option   

Sorry I'm I missing something?
       

[durandal]

Are you using the CGMiner version from Bitmain?

If you are, the BMSC commands are correct. I'm not on top of the various deprecations, but it did work for me as written!

I've run it on Windows 10 with the above, and the Zadig drivers worked fine.

Philspain - the --enable-icarus is a flag passed to the configure utility when compiling from source, you need to ensure that you've got a binary that has the U3 support compiled in, or compile it yourself (which I think I'd probably not recommend to you at the moment)
