Garbage psu multi rail so


Here is my guess.

One rail is 36 amps that is good for one pcie plug not 2
Second rail is 36 amps that is good for one pcie plug not 2
Third rail is 20 amps that is only good if your gear is set to 200 watts per pcie plug

So if your gear is set to 200 watts per pcie plug you can only do three plugs not four.

I would connect two pcie plugs

It should start on one of those patterns

With 3 rails of 36 36 20

You could get it to work on careful setup and big under clock.

Since the most a 36 can do is 18 x 12 = 216 watts.  A setting like 150 watts would be okay.

So .61 volts. And 150 watts would be good.

But you need to start it to downclock it to thay

What PSU are you using? Model and watts.

I would start at looking at that.   I never had to do the sd boot luckily. 

So, it's sure you need to re-build cgminer in 0.5.0 because --enable-blockerupter option isn't in the default build (it prevents others to be compiled).
Then did you do a "sudo make install" too after the "make" command? Try and reboot the Raspberry after that.

cd /tmp
git clone https://github.com/ckolivas/cgminer
cd cgminer
./autogen.sh
./configure --enable-blockerupter 
make
sudo make install
cp cgminer /var/www/minera/minera-bin/

Well, you should firstly try to remove the autodetect option (this should enable libusb detection). Then please can you tell me the exact hardware you are using? Can you find and paste a link to it? Because I'm not sure what you are trying to connect and I need more info about the HW before tell you something more.

EDIT: while I don't think it's a cgminer version problem this is the previous binary there was in Minera, you could try with this too (add it as custom miner or overwrite it as default one) https://github.com/michelem09/minera/blob/fa17a35255bdd7ba48569d0507dc0e9e4f788ecd/minera-bin/cgminer?raw=true

Last try is looking what the miner is doing while tries to start, so get a terminal window in Minera and try launch this command:


(stop any running miners)

If you are still getting "No devices found", try to run:


And give us the output

Well now, it could be useful know your settings... For example, you didn't answer me, did you tried with superuser mode?

You should try to run the miner command manually from the terminal and/or look at log

Hello

Update looks great but I havent been able to get it to work yet. I am running 2 asicminer tubes, they were/currently are running fine on 4.1. I tried updating to 5.0 and just using cgminer and bfgminer but neither of those worked. I then compiled cgminer using this



But that did not work either. It says no devices found, is there something I am not doing or doing wrong?

I will try to see if something happens when I plug it in but I can't try until I get back home from work. Also I have no idea how to recompile CGMiner is there somewhere that explains this process?

First of all you should look at the dmesg log when you plug-in the USB cable:

- SSH into Minera
- plug-in one Tube
- do "sudo dmesg" and look if something happened (you should see something like "usb 1-1: New USB device found,  etc...")

Then if USB are correctly detected you should need to configure the miner:

for Bfgminer it should work, you can try to look at this: https://bitcointalk.org/index.php?topic=769570.0

for Cgminer according to the readme you need to recompile it with the "--enable-blockerupter" option (this is not in the default cgminer on Minera) https://github.com/ckolivas/cgminer/blob/master/ASIC-README
