1  Bitcoin / Mining support / Re: USB ASIC ERUPTER - Setup & Config. BCG Miner, cgminer & Hubs "Oh Pi"! on: September 20, 2013, 09:08:30 PM
The network connection is USB also (on the motherboard of course)
You will most likely find in the system log a comment about the network device failing.

On mine I wrote a cron job that runs every minute and checks the network and if it's not working, it send cgminer a quit and shuts down the RPi
The main reason for this is that obviously pulling the power out while the RPi is running is a bad idea, and once the network dies it seems it wont restart without a reboot anyway

Sounds like Raspbian have screwed up something there with the update Sad

The network dropout isn't unknown, just it seemed to have become quite rare at least up until recently.
I've had it happen once on Arch (but only once) but a few times on Raspbian (used to sometimes happen when I plugged in an Icarus pl2303)

Interesting. Makes sense. Could you share your cron job ? It's not ideal but should get me hashing again until Raspbian gets a fix.

The last few entires in my syslog before I have to hard reset is as follows :

Quote
Sep 20 16:00:22 raspberrypi kernel: [   59.983209] netlink: 20 bytes leftover after parsing attributes.
Sep 20 16:00:22 raspberrypi kernel: [   59.983245] netlink: 20 bytes leftover after parsing attributes.
Sep 20 16:00:22 raspberrypi kernel: [   59.983392] netlink: 20 bytes leftover after parsing attributes.

I have done some more testing. I can't get the RPi to loose its network connectivity and need resetting apart from when running cgminer. I've tried hammering the NIC with heavy downloading and it handles it fine. I've removed all but 3 Block Erupter USB's just in case it was a power issue but it's not. Im running a D-Link DUB-H7 with 5 Erupter's total.

I wonder whats so specific about cgminer that causes the nic to hang under the current Raspbian...

So I got a kinda weird issue.

I started mining on my Raspberry Pi (O/S: Raspian) with 5 Block Eruptors on a DLink DUB-7 on August 19th using cgminer 3.3.4 and followed the included instructions on how to compile the libusb libraries myself. It worked great and it ran non-stop for a few weeks. The other day I decided to update cgminer to 3.4.2. After mining for about 20 minutes the Pi seemed to locked up. My SSH session died and I couldn't ping the Pi anymore. I figured it was just a fluke so I restarted the Pi but, again, after mining for about 20 minutes the Pi locks up.

I figured that this must have just been an issue with the newest version of cgminer so I went back to 3.3.4 with no luck. 3.3.4 now causes the Pi to lock up as well. I thought that maybe the Pi was overheating so I tried doing something else intensive; watching a 1080p movie over my LAN for 2hrs+ but it worked great and never locked up. I also tried mining just with 1 miner but the Pi still locked up.

Perhaps there is an issue with the newest packages for the Pi? How can I provide some more detailed info to see what is going on? Anything else I can try to resolve the issue?

I've also posted this issue in the cgminer thread https://bitcointalk.org/index.php?topic=28402.msg3121424#msg3121424

I'm getting the same problem here. Everything was running fine for weeks until I decided to apt-get update; apt-get upgrade the Pi and recompile from cgminer v3.3.1 to v3.4.3. I've also tried reverting to v3.3.1 and I still get a problem. This only seems leaves one of the raspbian (jessie) updates as the possible culprit.

same for me just now

Received mine 12am this morning. Trust given.

Took some tweaking of my raspberry pi but they are all happily hashing away right now. I needed cgminer 3.3.1 and dist-upgraded Raspbain from wheesy to jessie.

Many Thanks OutCast3k!  Smiley

Mine just started working Smiley Problem is I can't see what i did any different this time. It does mention here that you have to replug it in between trying different versions. I left it plugged in while i was trying different versions etc... Will post if I find out any more info that might be of use to others in the same situation.
7  Bitcoin / Mining support / Re: USB ASIC ERUPTER - Setup & Config. BCG Miner, cgminer, Hubs "oh my"! on: June 06, 2013, 12:33:34 PM
Yes. I will look further into the possibility that its a driver issue. My gut tell's me it isn't but I'm running out of ideas and suspect that perhaps the Erupter may be faulty :/

Thanks anyway Smiley

sorry, have to ask - hub is connected to external supply/wall wart?

Otherwise, your built in driver may be icompatible

I'm open to any other suggestions from other users ?

Thanks for the quick reply!

No I haven't installed any drivers. I just tried to build the one you linked to but it fails.

Ubuntu 13.04 uses the 3.8.0-22 kernel which as far as I know already has the driver built in. /dev/ttyUSB0 appears so I guess this implies it does. Here's my syslog when i plug the device in :

Jun  6 11:09:43 admin kernel: [59068.804377] usb 1-1.1.4: new full-speed USB device number 27 using ehci-pci

Jun  6 11:09:43 admin mtp-probe: bus: 1, device: 27 was not an MTP device

When I try and communicate directly with "screen /dev/ttyUSB0 115200" I get not output. Never tried this before so not sure if that means anything.

I would like to get this running on Linux (eventually my Raspberry Pi) and I don't have Windows so I'm unable to try any Windows programs / guides.

you've installed the driver?

(not sure if that was inferred anywhere in your post)


Also - a nice guide for win7 users is here:

Thanks for the thread. I got my Erupter yesterday but I can't get the damn thing to work :/

Here's what I have tried so far :

Plugged directly into Thinkpad X60 laptop USB (should be enough power).
Plugged into a D-Link DUB-H7 (same as pictured in an earlier post that shows it working).
Plugged into a PlusCom U7PH-3A.

When I plug the Erupter in the green light flashes 4 times then stays on.

lsusb shows :
Bus 002 Device 009: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

/dev/ttyUSB0 appears.

Ubuntu 13.04 with http://ck.kolivas.org/apps/cgminer/3.1/cgminer-3.1.1-x86_64-built.tar.bz2 (i read v3.2.0 doesn't work) I run :

./cgminer-nogpu -o http://eu-stratum.btcguild.com:3333 -u xxx -p xxx

tried these extra options too :

--icarus-options 115200:1:1 --icarus-timing short
--icarus-options 115200:1:1 --icarus-timing 3.0=10
-S /dev/ttyUSB0
-S all

Nothing gets detected and its "Waiting for USB hotplug devices" and just idle.

I tried bfgminer 3.0.2 too and that just CPU mines as it can't seem to find it either.

I also tried MinePeon on my RaspberryPi and get no results either.

Am I being dumb, have I missed something obvious or do I have a faulty Block Erupter ? Any ideas welcome Smiley

I tend to use Blockchain.info and their PingIt service. VERY quick! Almost instant. They tend to run out of Bitcoins quickly though.

Hey all. Got into Bitcoin just over a year ago. Fascinating! Only just bothered to register here.
