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#msg5604625if 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

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?

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.

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 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 lcettuzzi

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? -bobby

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.
