  Heeeelp!

Hi.

Two days ago I got a Gridseed 5 chips miner. I tried almost everything, but my computers don't recognise the miner. On Win7 Ult x64 I get always 'USB device not recognised'. I tried to install the two different type of drivers mentioned in various fora and blogs, I tried to substitute them using Zadig. Nothing worked.
Then I tried under MacOS 10.9. Same result.

Has somebody an idea? I have three graphics cards, a BlockErupter USB miner and a BFL 25 GH/s miner all working perfectly. But this Gridseed miner I driving me crazy!!!

Every idea is welcome.

I'm using this:

I had major problems with my Pi's power and using the USB ports.  First it started to lose the ethernet connection, then it would just start shutting down and rebooting.  I ditched the whole controller and bought myself a Cubietruck and could not be happier.  It had built in wifi and so far so good running 20 gridseeds. 

OK,
I can run 13 miners on a 13 port powered usb hub with no problems.
When I add the second hub of 13 into the second usb on the PI, The Pi crashes every few minutes.
Anyone have this problem?

Hi Milkman, Ihave been running 12 of this..... the 13the port I have plugged in my pi.

Thanks can you recommend a 13 port hub that works with Raspberry Pi?

Get a 13-port hub and a 10-port hub, and don't use the splitter. Or get two 13-port hubs, in case you want to connect a few more donuts later. The goal is to keep max 2 levels of daisy-chained hubs, and any hub with >7 ports already has 2 levels inside.

I'm planing my Gridseed farm setup. Can someone tell me if this will work? I want to attached 20x Gridseed to 1x RasPi. I will be using 2x Roswell (RHB-500) 10 port USB hubs. But I would also like to use a usb wifi adapter. Will the following non powered USB splitter work? Assuming I hook up the the wifi adapter and 1x 10 port usb hub to 1 USB 2.0 port on the RasPi. The other 10 port usb hub will plug directly into the 2nd usb 2.0 port on the RasPi. My alternative would be to get a wireless bridge and hook up a Ethernet hub. But my preference would be to use a mini wifi adapter.

then don't use hashra's image - just follow the steps in the very first post on this thread like I did.

For some reason, I can mine at 850 with cgminer on windows, but when I use the RPI with the Hashra image, I can only go to 800 before HW errors start to get excessive. Im trying to keep the HW errors below a handfull every minute (a few thousand per day per miner). Is that typical or kinda high?
Im running 5 miners on windows with maybe 1-2 HW errors per day at 850, but on the rpi, im getting several thousand per day running at 800. They are pretty evenly spread accross all GSDs.
Is this a known issue with rpi?

I've been running 20 gridseeds for nearly a week now on a Pi Rasberry with cpuminer and have never had to reboot and they have not missed a beat, I'm running at 900 and averaging 350 to 370 Hk/s

I have seen people using CPUMiner with 10 units and not needing to reboot them

(From the cgminer-3.7.2 README.txt)

--hotplug      Set hotplug check time to seconds (0=never default: 5) - only with libusb

what is --hotplug in cgminer ?

can anybody help me running 10 unit on windows? :x

Thanks Jaimie.

Is it better to run CPUMiner instead, or does that come with its own reboot issues as well?

the problem is known, someone made some kind of file that will reboot them every x hours

Any hints for Windows using CGminer 3.7.2? Mine will run for about 6-8 hours, then they need to be unplugged (USB) and plugged back in. Very weird.

Stability fix for PI users.

I was having a terrible time getting my rig to run long stretches in Scrypt mode with any real stability regardless if i was using cpuminer or dtbartle (cgminer 3.7.2). I picked up this tip from another thread were they were using Scripta. I applied only the stability fix portion from this thread to my PI which is otherwise configured per this guide. My rig is now stable using either cpuminer or dtbartle.

if your having stability issues in long runs on a PI I would give it a shot.

With great thanks to this guide and many hours of research and experimenting I have created an image to run on the raspberry PI that automatically dual mines btc/script at the same time with the Gridseed5 chip. Once written to the sd card and booted up, it will auto log-in and start BTC mining in about 15 seconds and then 15 seconds later script mining kicks in.  I have been running for over 36 hours now with no issues whatsover.  Average hour hashrate with 4 units has been 40GHS BTC and 1250KHS script. The image is createdfrom Raspian with all updates as of 3/21/14, cgminer 3.8.5, and cpuminer.  This was created on my 8GB Sd card with expanded file system in Raspian, so I assume you will need at least that big of a card to write to.  If I had known this was going to work so well I would have written to a smaller SD card as it only takes up 2.5Gb.  I will try to figure out how to shrink it down to fit on a 4 GB card in the future.

User "miner", password "raspberry", ssh port 22

You will need to edit the following files for your own pools:
/home/miner/minebitcoin.sh ( nano ./minebitcoin.sh )
/home/miner/minescript.sh ( nano ./minescript.sh )

For script mining, you have the choice to use all devices under one worker, in which case you only need to edit /home/miner/worker_All.sh to enter your pool info. ( nano ./worker_All.sh)

It also has the option to use each device under separate workers, I have included 4 scripts that correspond to my 4 gridseeds named /home/miner/worker1.sh, worker2.sh, etc  You will need to edit those scripts ( sudo nano ./worker1.sh ) and add a new worker for any gridseed beyond 4 devices.  

CPUMiner should automatically assign tty into the startup script and launch for each device as long as you have filled in the number of devices in ./minescript.sh

To mine only scrypt, nano ./automine.sh and comment out the bottom 2 lines, and nano ./minescript and remove " --dual " from the config

Log in info is as follows (please change with passwd and sudo passwd commands):
username:  miner
password: raspberry
sudo password: raspberry

Let me know how this works for you, this was built and tested on my particular gridseeds from my purchase from zoomhash last week (shows STM.....)
