I think that the idea of payout threshold was already discussed here, but I couldn't find the right topic.
I do mining as a hobby, and my mining rig has very limited hashpower (Antminer S5 + a bunch of USB dongles and pods). Payouts from the pool that I receive daily are quite small, which makes spending them virtually impossible (as transaction fees become much higher than the value of the "dust" itself).
It would be nice if rewards could "build up" in the pool until some user-defined threshold (e.g. 0.1 BTC) was reached.

Bitamin Antminer S3 bitcoin miner is for sale. Specs and review here: https://www.cryptocoinsnews.com/review-antminer-s3-450-ghs-bitcoin-asic-miner-bitmain/Excellent condition, now hashing 24x7 at full power. Modified firmware with latest cgminer is installed.
I have two of them + plus Dell 750W PSU w/breakout board and cables. One of the units comes with a Wi-Fi antenna. 1 x S3 = 50 SGD 2 x S3 = 90 SGD 2 x S3 + PSU = 120 SGD Local pickup only. |

Hi,
seems that I was firewalled by kano.is today, as I can't connect to any of pool mirrors anymore.
My ip address is 81.25.54.131. Is it possible to remove me from the black list?
only cpu mining at that address, your other addresses weren't so didn't get blocked ... Please unblock this address too. I ran CPU mining just as a stress test for a new single-board computer, but forgot to put cpuminer into benchmark mode instead of pool mining mode. |

The app keeps saying that I have "No Internet Access" (which I actually do have, of course). I entered correct user name and API key, but with no effect.

I run cgminer 4.9.2 on Raspberry Pi 2 and experience constant segfaults (once in every half hour) when Antminer U3 is attached.
I use only minimum set of command line options to start cgminer, just a server URL and login/password (everything else is by default). Source code was taken from official git and compiled with gcc 4.9.2. I used CFLAGS="-O2 -Wall --march=native" compiler option and "--enable-icarus" configuration option. Linux version is 4.1.7.
Other instances of cgminer (configured for Avalon Nano ASICs) work just fine at the same time. Also, I tested same version of cgminer under MacOS X with U3, and it seems to work stable, too. So it looks like some issue with specific setup of cgminer + Antminer U3 + Raspberry Pi 2.
Is it a known problem? Is there any patch around? Anybody interested in core dumps?

Here is my script. Maybe someone will find it useful to run cgminer in multiple-vendor environment. #!/bin/bash

do
usb_options="$(cgminer --ndevs | grep ${device_id[i]} | awk '{ print $5":"$7}' | xargs | sed 's/ /,/g')"

No there isn't because too many devices use the same damn usb communication chip without any added identifier for cgminer to tell them apart and blindly use the 1st fpga/asic driver from cgminer (icarus) in different ways. The icarus commands were never designed with different devices in mind but new devices+drivers continue to come out that use that driver as though it's the only device connected.
My devices have different USB chips and vendor IDs: $ cgminer --ndevs [2015-10-17 23:18:08.516] USB all: found 11 devices - listing known devices .USB dev 0: Bus 253 Device 3 ID: 1fc9:0083 Manufacturer: 'NXP' Product: 'VCOM Port' .USB dev 1: Bus 250 Device 5 ID: 10c4:ea60 Manufacturer: 'Silicon Labs' Product: 'CP2102 USB to UART Bridge Controller' [2015-10-17 23:18:08.518] 2 known USB devices But I understand that it's not always the case. Maybe it's reasonable to add some optional modifiers to icarus (or any other) settings that will allow to specify device bus ID/ID/vendor ID which these settings belong to? BTW, I just found out that RPi 2 only has just one USB bus (and all it's four USB port sit on it), so --usb 1:* approach doesn't work for me. It seems that I have to write some script now, which analyzes lsusb/cgminer --ndevs output, sorts devices by their vendor ID into groups, and then runs different cgminer instances with specific options for each group. It would be nice to have all this out-of-box, of course) |

Does avalon nano actually work? Actually it works just fine with --icarus-options 115200:1:1 and --icarus-timing 0.22 settings, maybe with HW error rate on a relatively higher side (~7%). The easiest way would be to find which ports belong to different usb buses and then put the nano on one usb bus and confine that cgminer version with the --usb command. I understand that, it's just not very convenient in my configuration (Raspbnerry Pi 2 + 12-port USB hub), where all the ports in the hub belong to the same USB bus. I need separate USB hub for each device family, etc. That's why I asked my question. But if there is no way to run all devices from just one cgminer instance, then I will have to rearrange hardware somehow. Thanks for your answer. |

Whatever reason you want to use timing is wrong. You almost certainly do not want to adjust timing. Any options you are likely to really want to adjust for different devices are device specific anyway (like --au3-freq). Trust me, whatever reason you think you want to use for timing is misguided.
For instance, --icarus-timing 0.22 seems to be required for Avalon Nano 3 ( https://en.bitcoin.it/wiki/Avalon_nano ). Otherwise, cgminer shows ~500 KH/s rate instead of ~3.6 GH/s, and the device is idling most of the time according to its status LED and temperature. However, this timing is clearly inappropriate for ASICMiner Block Erupter that I'm trying to use at the same time. |

I have a simple question regarding cgminer that I failed to find an answer to in README and other sources.
I'm experimenting with my hobby project with the following setup of 7 ASICs:
- ASICMINER Block Erupter (x4);
- Avalon Nano3 (x1);
- Antminer U3 (x2).
All these devices are supported by the same driver (icarus). However, I would like to use different driver options (like timing) for each specific vendor. Do I have to run three different instances of cgminer (manually restricting each of them with --usb option), or it is possible to specify separate set of options for each group of devices within one instance?
