It is strange.... after trying the antminer u3 with the cgminer for a few hours. the cgminer always crash or the miner became a zombie.
Anyone know how to get rid of the following errors: GetResults usb read err:(-1) LIBUSB_ERROR_IO attempted reset got err:(0) LIBUSB_SUCCESS
The longer the device runs the more it appears until the u3 becomes the zombie
I was getting this before I put it on a powered hub.

The problem is that I did not see any output. It looks like a user press the "q" for quitting the cgminer. After running it a few times, it is running longer. now it already running 3 hours without a break. thanks again for the advices. I was almost in the position to resell the stupid antminer U3

What would everyone suggest as a good backup power supply to replace the crap one that the Antminer U3 came with? Amazon links if they carry it preferred...
6A one from my rockminer guide.I really think we are all going to have to switch to ATX computer PSU's with breakout boards for these U3's. Dogie I bought one of the ones you suggested after my first stock PSU melted. The replacement one you suggested lasted 4 days (at least it didn't melt or catch fire, it just died completely). I had previously had 3 of those also die while using them for my R-boxes (the 5A version) but I just replaced them as they lasted 2 months before dying on me and I got them cheap ($6 each).

You have to remember, most of the time when someone like dogie suggests an item and it contains a hidden link to Amazon or the like, he has an associate tag embedded and receives commission on EVERYTHING in your shopping cart. Not just that one item. So please don't trust those links. Don't click on them. They force your cart to give him commission for the next 24 hours! Trust anyone else who links. Also cross check ratings of those products with other reputable outlets. newegg, overstock etc. Whilst you may not be able to purchase from them, you can at least trust their rating systems over Amazon.

They're the same ones I'm using, and none of mine are even warm... Send it back and get another one.

......
Cool: U3s remain cool and quiet due to its 80mm fan which quietly exhausts air out the side of the case.
Stable and Accurate: Based on the tried and tested BM1382 chip, the U3 is extremely stable and is able to run 24 hours a day without problems.
Exquisite: The refined design of the U3 allow it to blend on any desk or shelf without standing out.
After running a few days.... Actually I don't think it is quiet. After running it on the table for a few hours, I feel annoyed of the sound from the fan. And the other point about putting on the desk: I won't recommend it. It is making too much heat on the table.

Ok I wanted to share my experience with this miner cause I'm getting a little crazy but I finally think I have it under control.
At first I want to put some complains about the instability of this miner. It can/will guarantee crash after running for a while.
My setup is a raspberry pi with a raspian image. At first I had my miner hooked up without any additional things. This way it crashed every, let us say, 24 hours.
I've build myself a relay that can be controlled with an arduino like board and controlled it to my server (a home pc running linux) When I have no response in the pool for about 1 minute my server will automatically reset the relay with a power surge of 10 seconds.
I also connected a tinny display to monitor cgminer as it was running (this was my biggest mistake)
My setup worked very well only the board was now resetting every 10 minutes. This would mean that my miner running at 63GHash was crashing every 8 minutes. This gave ma an average of 43Ghash After several days of browsing and surfing I found that it was my tiny display that was taking to much current.
If you want to run a miner from a raspberry pi be sure that nothing else is connected to the raspberry pi. Only the miner!!!
Now my setup is working 100% and I finally hope I can enjoy the fun of mining :p
Regards
Xump
ps: The error I recieved if anyone is searching for it was LIBUSB_ERROR_TIMEOUT and I saw my device disappearing in the /var/log/syslog

I have an U3 and I'm currently getting an average of 40 GH/s. Is it safe to overclock it? And which parameter do you guys reconmend? ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I apologize @Alesfatalis could you tell me what distribution you put on your raspberry, and if you can give me the procedure to install cgminer above to rotate the u3. Thank you in advance
For overclock in your cgminer.conf :

@thephenix83 I'm using raspbian on my pi. To install cgminer you simply do this: sudo git clone https://github.com/ckolivas/cgminer.git
cd cgminer
sudo apt-get install build-essential autoconf automake libtool pkg-config \ libcurl3-dev libudev-dev
sudo ./autogen.sh
sudo ./configure --enable-icarus
sudo make install
