I see what’s going on here. It seems like you’re having trouble getting Ethereum running on Ubuntu with the latest CGMiner version (3.3) and using p2pool, which is a multi-miner pool.
After doing some research, I’ve found that there could be a few reasons why Erupters isn’t stable or working as expected on your Ubuntu machine:
- Erupters USB Mode Limitations
: Erupters, a type of Ethereum mining hardware, have special requirements for their USB ports. They must support a PCIe x4 interface and at least 5V. Unfortunately, some older GPUs, including those running the latest CGMiner version (3.3), may not meet these requirements.
- CGMiner USB Mode Configuration: While CGMiner supports multiple mining modes, including USB mode, additional configuration is required to make it work properly on older GPUs, such as Erupters. The “–usb” option is required, but some older versions of CGMiner may not support this feature by default.
To resolve the issues, try the following:
Ubuntu 12.04 LTS x64:
- Install the required packages:
sudo apt-get install libusb-1.0-dev libssl-dev librt-dev libcurl4-openssl-dev libblockdev-mmx2-dev
- Update your system:
sudo apt-get update
- Install the “usb-1.0-dev” package to enable USB support for older GPUs:
sudo apt-get install usb-1.0-dev
- Update CGMiner to a version that supports USB mode:
sudo apt-get install cgminer=3.2.10.5
Ubuntu 14.04 LTS x64:
- Install the required packages:
sudo apt-get install libusb-1.0-dev libssl-dev librt-dev libcurl4-openssl-dev libblockdev-mmx2-dev
- Update your system:
sudo apt-get update
- Install the “usb-1.0-dev” package to enable USB support for older GPUs:
sudo apt-get install usb-1.0-dev
- Update CGMiner to a version that supports USB mode:
sudo apt-get install cgminer=3.2.10.5
`
Using P2pool:
“p2pool” is another Ethereum mining software that can use multiple miners (in this case, eruptors). Here are some steps you can take:
- Install p2pool:
sudo apt-get install p2pool-ubuntu
- Update your system:
sudo apt-get update
- Configure p2pool to use multiple miners (in this case erupter):
p2pool --miners=1:cgminer=3.2.10.5 --net=eth
Remember that you need to replace “1” with the index of the erupter Miner and “3.2.10.5” with the version of CGMiner you have installed.
Additional troubleshooting steps:
- Check your system’s USB ports and make sure they are supported by erupters.
- Make sure your CGMiner drivers are up to date, as an older driver may cause issues when using USB mode.
- Consider using another Ethereum mining software, such as CGMiner or Ethminer, which may be more compatible with your system.
I hope this helps resolve the issues you are experiencing!
