wolfey,

how much do you think I can overclock the gridseed by doing just the pencil mod and bridge mod? the last remaining mod is a bit out of my leage,

and you are a continent away so I cannot send them over to you that would be really not cost effective haha^^

The resistor mod is necessary to clock over 950MHz stably. Especially to even get 1000mhz to be stable and pretty much hw error free.
But, if you can do the solder bridge, you should be able to do the resistor replacement just as easily.

Best performance is with all 4 mods. That's just the way it is if you don't want to have to put up with red nuisances 'nonce's' Wink

Any way to get bfgminer to display more then just 15 GS units? I have 28 hooked up but can't see what they are all doing. Windows BTW.

To your opinion, if runing 4 gridseeds, CPUminer is the best one to use for a noob?

Definately cpuminer ! Perfect for newbs!

I have some problems connecting these to a Windows PC, I tried to follow the guides provided. The problem is, when I connect the HUB all devices show up in the device manager. I can't install the Zagig driver of the HUB (because 10 devices show up - see screenshot) and therefore I can't start CGminer. CPUminer works if I specify a specific COM port for a single unit. My preference strongly goes to get this working on CGminer since I want to over clock and monitor via the API.

Any suggestions?

Sorry for the shitty screenshot

Your best bet is to give BFgminer a try. No extra drivers required and if you want to persue the cgminer route you need to add the zagig driver to all instances of the ST driver under com ports.

You can find it here

After much searching,questions and testing this what I learned about the Pi.
The Bit Fury guys have done alot with the Pi, They were having the same issues with Hub sizes and levels.
Seems that the Pi can run 20 and thats about it, Anything after that the network drops and gets laggy as hell. It's finicky with usb hubs. http://elinux.org/RPi_Powered_USB_Hubs

You will not see a hub over 10 for a Pi in the wiki.

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.

Bye

Did you try this?

http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/

Thanks.

I already tried this but I doesn't work.

I'm wondering if the miner is correctly working. Perhaps there is a hardware problem.

Thanks aganin.

Bye

Thanks man. I wonder with three "ports" if the netbook actually had three USB controllers. Only one way to find out.... Wink

One way I know is list shown under Device Manager/Universal Serial Bus controllers. Roll Eyes

Is there a theoretical limit of Gridseeds we can run on a Windows machine? I have my original 10 hooked up to an old Windows7 netbook and its slick...I love it. It only has 3 USB ports. How many hubs can be daisy-chained off just this one machine?

The USB Spec states 7 addressable bits so 128 total devices - 1 for the host address which leaves 127 devices PER HOST CONTROLLER. Each controller is also rated to support up to 5 levels of USB devices.

The cheaper the hub the less actual ports that are allowed. Either way when you plug in a USB hub you lose at least 1 available USB address for the HUB itself. Many of the cheap hubs (like the 10-12 port ones I use for $8) contain 2 internal HUB's self + 1 so I lose 2 addresses per hub and can connect 9 devices (+1 hub) to it.

After this it gets to be like time travel.

3 ports with 1 12 port hub in each (with two internal hubs) = 36 ports usable, 43 addresses used.

Daisy chain in another level and you get another 33 ports (36 - 3 used) and cost another 42 addresses = 85 used.
Plugging into the same hubs again you get another 33 usable ports and cost 42 addresses which should max out the controller in the laptop

So 8 bits, 128 addresses, 7 12 port hubs, 102 usable ports.

EDITED.

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

What hubs are you using?

Getting flatrate electricity soon, so any dual mode mining with cg/bfgminer on the horizon? Preferably linux based.

Soo, the whole thing about 2-levels of USB hubs is only for the RPI and doesn't apply to Windows/Linux host configuration?
With the 2-level limit, I figure you could get at most 49 ports (7 primary with 7 secondary on each primary)...
Is there a limit to the horsepower of the PI which limits the number of GSD devices, or could it run all 49 successfully?

I can't run 10 cgminer instances on the PI so I don't know. Running one instance with lots of devices is much different. Since I primarily host/lease I have to run one instance of the miner per seed and open one api port per seed.

Here is a sample of USB trees: I count Self =0 + 5 levels deep. 17 seeds on 2 12 port hubs. I might have mapped that wrong. sorry.

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?
-Bobby

I'm not exactly sure that its a Pi issue. Might be the hubs.
Anyone running 26+ on a Pi?
What hubs are you using?

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.

Thanks for the tip. The Cubieboard2 looks like a safer option. I would hate to buy several Raspberry Pi and discover that it doesn't work with two 13 port usb hubs.
