This reply is not related to the exact topic but you did ask this question in your post:

Also is anyone using a Raspberry Pi to do this as I want to move it to a Raspberry Pi which makes more sense power wise?

Yes and NO.

I am running cgminer 4.8.0 on Rasbian Wheezy on Rasberry Pi+. I bought two Antminer U3 but I'm just trying to get one going.

I'm getting the same LIBUSB_ERROR_PIPE you were seeing on Windows. It does recover, however, and I'm hashing at 30-50GH/s at ghash.io. When I get lots of errors, my hash rate goes down, obviously. As of this writing, I would recommend running this on the Pi since the power is almost nothing to run the Pi and a powered USB hub. The only power is really for the U3.

Good luck.

Here's my output:

I bought one of these from minersource. Antminer U3. Had tons of problems getting it going.Ended up cutting the plug end off the supplied power brick and splicing it into a atx computer power supply. Then spent many hours researching and came up with the following line in my bat file:
cgminer.exe --bmsc-options 115200:0.5 -o yourpoolinfo -u username -p password --bmsc-freq 0B82 --bmsc-voltage 0800 --queue 1 --scan-time 30 --expiry 60 --no-submit-stale
I am getting a pretty good hash out of this.Averaging 73.4 gh/s. Don't know how to post pictures here or would give a screenshot.
Using the cgminer from bitmain
Used zadig to convert driver to winusb

I am new here but do have some experience setting gear up. i currently own 2 Antminer S1, 2 BTCGarden Units, and do gpu mining. I also help out as a staff at freicoin.us.

Have you checked what the pool is showing for your hashrate for that U3? I doubt it's 73...

Ok so after spending some time on the phone with someone in support from bitmain. It is at the very least hashing. I wouldn't say correctly, but hashing. (Corrected as I typed it....) Now it is Zombie again....

So has anyone actually gotten theirs to work at the right speed?

Also is anyone using a Raspberry Pi to do this as I want to move it to a Raspberry Pi which makes more sense power wise?

Steps used in getting the U3 to somewhat work:

1. Installed Zadig WinUSB Driver Version 6.1.7600.16385 [WinUSB (v6.1.7600.16385)]
2. Downloaded CgMiner Directly from Bitmain Support Site "https://www.bitmaintech.com/support.htm?pid=007201404130633105772QFG6R2u0635"
3. Ran THAT CGMINER with this command line: cgminer.exe --bmsc-options 115200:10 -o nl2.stratum.io:3333 -u magicstix.mainpc -p x --bmsc-freq 0982 (This is where I wonder if the Voltage Arg is required or not?)

After this is would run for a bit then CGMiner would report libusb errors or -9 and also eventually zombie out.

Any help here?

where did you buy the Antminer U3?

Sorry for my Bad English
Thanks advance
and
God Bless!!!!!

Heya,

I bought one as well. However, I realized that it kept on saying incorrect device overnight. Just today figured I was going to get to the bottom of it. The hash rate is not an issue for me, Mine runs around 40 - 58 Gigahertz /s. I was having an issue with detecting it at first.

Would like to see why it's having these issues though. there is four screws at the bottom of mine, and when I put something to lay on top of it while upside-down, it HAS not since, had a detection error in cgminer? I'm not a big hardware expert or anything of this sort, and just a simple 3D artist, so not sure what's up with that...

all in all it doesn't matter to me, everyone in my house seems to want to get me a Zeusminer volcano or a C1 for my upcoming birthday, oh goody.... I'm sure as time moves on it will all be figured out lol.

Ok so I have attempted to give the unit a better Power Supply with not much more luck.

Sometimes it hashes around the same usual 6-12GH/s then fails or just flat out fails. When it attempts to reload the miner in cgminer this is what I get:

Code:

Well I attempted your settings and it tried to mine fast but HW Error's none stop so I am thinking it is due to the power brick this thing came with. Any idea's if the gridseed power connector's would be the same? Otherwise I am headed to Fry's to build one lol.

I bought one of these from minersource and it gave me extreme grief getting it going. It is still falling short of rated hash but atleast i got it doing something half decent. Using the cgminer supplied by bitmain. Converted the driver to winusb. Modded power to a atx psu for more umph. Using this comand line in a bat file:

cgminer.exe --bmsc-options 115200:1 -o stratum+tcp://freicoin.us:4334 -u username -p password --bmsc-freq 0C82 --bmsc-voltage 0800

Thanks trying this now. I will post what I find as I can add it to a Dell 750 that I have running from minersource.net. I also got my U3 from there as well.

Again tried a lower Freq which seemed to let the miner hash for longer but it still just shut off with the same Zombie errors.

Hoping this is an issue with the software and not a bad miner.....

So after playing with it a bit more I went for this command line which seems to be stable but still not hashing correctly. "cgminer.exe --bmsc-options 115200:10 -o nl2.stratum.io:3333 -u magicstix.mainpc -p x --bmsc-freq 0882"

Still getting Lib USB Errors:

Code:

Then it will randomly goto:

 [2014-11-11 14:02:31] AMU 0 attempted reset got err:(0) LIBUSB_SUCCESS

 [2014-11-11 14:02:52] Bitmain detect (6:1) failed to initialise (incorrect device?)

When it does stay stable for 5+ mins (Which is random at this point in my eyes) cgminer reported 3GH/s and Ghash.io Reported 8.03GH/s. So I would trust the pools report at this point with those command settings.
