what is --hotplug in cgminer ?

(From the cgminer-3.7.2 README.txt)

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

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 witch is otherwise configured per this guide. My rig is now stable using either cpuminer or dtbartle.

https://bitcointalk.org/index.php?topic=482352.msg5604625#msg5604625

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

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.

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

Thanks Jaimie.

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

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

[jjj0923]

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

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?

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

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.

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.

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

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

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?

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.

  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?

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.

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?

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?

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.

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.
