Cgminer 4.9.0 on raspberry pi 2 support needed.

[tidioute06]

So I'm trying to setup cgminer on a raspberry pi 2. This is purely for fun/educational purposes. I have a block erupter and two bitfury asics. I followed adafruits guide. Unfortunately cgminer 3.1.1 is no longer available. I'm using cgminer 4.9.0. I followed all the instructions (being a Linux noob) and I can't get cgminer to open. I get the error usb init, open device failed, err -3, you don't have privilege to access

After looking through the cgminer Readme I thought it might be a permissions issue. I tried what the guide recommended but I either don't understand it or have done it wrong. I got cgminer working with the same hardware on my windows pc so I know the miners are ok.

Any ideas?

I found v.3.1.1 on github in a few seconds: https://github.com/ckolivas/cgminer/releases/tag/v3.1.1   Might want to give that a whirl. I'll follow this thread and help best I can. Good luck!

Also, ensure that you have the latest usb drivers for your OS. I admit I am not super up-to-date on RasPI's I have mined using other ARM devices under Arch linux though.

Oh wow thanks. I'm new to bitcoin mining and linux. I'm really looking to learn but the amount of info for a newbie is a bit overwhelming lol. I'll give the 3.1 a try and see what happens.

Don't forget that when building cgminer to enable icarus and bitfury support in the configure flags. (adafruits guide may mention this) .

[tidioute06]

It does. So is icarus like a usb driver for linux?

No, icarus supprt is what will be needed for your block eruptor. Usb support should already be enabled in raspbian (which I assume you are using). I'll see if I can dig up some more info if you have continued trouble.

I'll direct you to the exact line in the readme
https://github.com/ckolivas/cgminer/blob/master/README#L426

Also no idea why you went with 4.9.0 since 4.9.2 is the latest.

So I got it to atleast see the bitfury miners. Still no luck on the blockerupter. I'm still getting the usb failed to init error..I'm really at a loss.

I followed all that in the readme. i get: cannot stat '01-cgminer.rules' no such file or directory
I know the folder is there. I can see it but for some reason it won't let me run the command. Like i said I'm a newbie at linux. I'm probably doing something incorrect.

You need to be IN the folder when you run it.
