Alright, I've been playing with this thing all day. I've targeted it down this issue. [2017-12-10 16:15:41] Network difficulty changed to 20.4k (146.3G) Any time this happens the miner stops running. You can hear the fan wind up a little as if there's an increase in juice that was being used for the processor. Now the yellow light just flashes every few seconds. Once at this point, unless I restart everything, it won't work on any changes. I'm at a loss... please help. Honestly looking for some help please. Whenever network diff changes new work gets sent to the ASIC and its restarted, sounds like your USB port/Hub is not providing enough power. When new work is sent to the ASIC is when it has the highest chance to get stalled because of power transients the hub can't keep up with. Beta testing of my new update that resolve this issue and similar issues that cause the sticks to go dead and need restarting is going well and should have a binary release tomorrow. This should also keep sticks alive from poorly tuned/unstable voltages etc. Pic below is a bunch of sticks running the new driver that I have purposely undervolted so they are unstable....driver has kept them alive and hashing for over a day now with no manual restarts needed!  changes are already pushed to my GitHub for anyone that dosent want to wait and can compile on their own. |

Hello,
My miner doesn't run for more than 5 minutes until it gets hung up and blinks the yellow light occasionally (stock settings). I'm running BFGminer 5.4-FutureBit2 for Mac on OSX 10.13.2 Beta. I see it happen whenever there's a difficulty change but not sure if its coincidence. I've tried changing from Mining-Dutch to Prohashing and still having problems with the miner working. I guess I get confused as it works fine initially then gets hung up. I also thought maybe a cooling issue but again, playing with the settings didn't change the problem.
As for a different topic, I'm noticing every time I start BFGminer its pulling up URLs that I've used in the past. How do I clean out BFGminer to stop bringing up previous work. I want a clean slate at each boot up with only 1 URL that is defaults to. I've edited the start-moonlander-2 to read this:
#!/bin/sh
cd -- "$(dirname "$0")"
cd bin
./bfgminer --scrypt -o stratum+tcp://mining-dutch.nl:3322 -u JustAnotherPLT.2 -p d=128 -S MLD:all --set MLD:clock=600
Its still loading with multiple URLs.
Sounds like your Mac's USB port is cutting power. Ive seen this on my Mac as well if the stick tries to pull more than 1-1.5 amps. Try lowering core voltage, stock voltage is too high if your only running 600 mhz. |

I'm having trouble trying to solo mine a small coin, nyancoin, directly from the wallet. It seems to start up ok, but immediately after a new block is found in the network, one or two minutes, then the miner is declared sick by bfgminer and presumably stops working (I let it run for a day or so in which time should have found a bunch of blocks)
Any ideas for a fix?
I dont believe bfgminer has support for scrypt solo-mining. (unless your mining off a solo pool directly). |

static diff
stratum+tcp://hash-to-coins.com:4444
works fine for mine
d=512 in the worker password field and in -p d=512
Going to try this out this afternoon, thanks! Maybe a bit offtopic, or not, but if i'd not specify the difficulty and just leave in password, will it use the default 8192 difficulty? What would be pro and cons about using 8192 instead of the 512 you mention? For now it's hashing 4.33 Mhs on 768 mhz it will just take 16x as long on average to submit a share to your pool. On average you will be hashing at 4.33MH but if you look short term you'll see crazy swings from like 20MH down to .5MH on pool side. This is the same reason some newer people think they are not working, because most pools have initial diffs set to 8k or higher for larger ASICS so takes forever to submit first share to pool(or 256k like nicehash had...guess we don't have to worry about them anymore  ) |

Same here - ordered from bitshopper.de
i'm glad their aren't a lot of people trying to buy these in bulk and resell them for a profit - i think the guys have put in a tremendous amount of work to get this launched and open up mining, for a low price, to the masses.
Yep, my distributors and I have lots of checks in place and have put alot of effort to keep these as affordable as possible and put in the hands of as many new people getting into mining as possible! |

The fans on these sticks may not be good.
One now shudders making noise and vibrating the stick.
I pull the two fans and now use external fans all is well in fact better then when I ran with the little fans also not as loud.
I can not find it but someone else said their fan became unbalanced and vibrated.
This happens even though the fan screws are tight and correctly installed,
I have similar issue with fan ( only one of the 3 sticks ordered ). Time to time starts making really annoying noise ... i also think is's increasing in speed as the noise level is increasing as well (and i can feel unusual vibrations when touch it) but after restarting the miner it's back to normal. I also tried to tighten/loose the screws but that just change the noise frequency (pitch or what it's called)  ... I have quite wide range of fans on hand so will try to find some that fits ... so no big issue. But have other question. Wanted to put one of sticks on USB cable and put it between window frames to keep it cold ( i have double windows in my house ) ... miner recognize the stick (green led is on) but won't show any hashrate (just zeros). Can be the long cable cause of this issue? It's 2 meters long. I tried it with shorter one (1 m) and that works well. Anyhow, OP you did a great job, thanks for these awesome miniminers. yeah trying to figure out how many of us have this fan issue. and it looks like that stick has more issues. I seem to have 1 good one and one bad one. Try to loosen the screws. I originally had mine too tight and the fans would be very loud, but if I loosened them a lot, it definitely helps. Keep in mind the are not the highest quality fans unfortunately. When I decided to add the fan thermal setup halfway in development I didn't have the funds to buy higher end ball bearing fans. These have a sleeve bearing, which after it wears in has the side affect of increasing the fan speed. They are supposed to spin at 10k RPM, but I have measured some that spin up to 13-15k, so at those speeds they get noisy and vibrate more. |

Yes, anything past a few feet probably wont work. The USB chip on this actually uses the older USB 1.1 standard, which has limits on wire length. |

Linux noob here. Could some one include detail instruction for installing the driver.
I am running ubuntu 17 with kernel: 4.13.0-17-generic
I was able to do:
1. make ( your cp210x driver )
2. cp cp210x.ko to /lib/modules/4.13.0-17-generic/kernel/drivers/usb/serial
but is unable to do step 3:
insmod /lib/modules/4.13.0-17-generic/kernel/drivers/usb/serial/usbserial.ko
i get output:
insmod: ERROR: could not insert module usbserial.ko: File exists
when i try the insmod with --f i get:
insmod: ERROR: could not insert module usbserial.ko: Invalid module format
.
When I plug into the device and run the script it can't find the device even after i select option to add devices and chose auto. I assume this must be missing driver.
Could some one help me with some detail instruction. Thank You.
You don't need to install the UART driver under linux, its already included in the kernel. Thats why it says file exists. |

Well got an email from Bitmart today regarding my moonlander-2 order. after 2 months waiting, they tell me to send an extra $60 for shipping.  wtf. are those guy's a scam or what ? didn't you checked your resellers, or what ? Sounds like you don't live in South Africa? He's my south african distributor and has been vetted. Don't expect shipping to be cheap if you don't live there. That i do not live in SA should not be a problem. I payed for the Moonlander2+tax+shipping! now after almost 2 months they start nagging that they want more money .. it's there problem, not mine... a deal is a deal. you should remove them as reseller. they are a con!! Please PM me with your order details and ill have it taken care of. |

i love me some low difficulty. time for us miners to make a quick buck and not the hashpower whales. mine on!
Any competent miner would have backup pools setup...the 40 terahash of scrypt is already piling on the LTC blockchain. |

Hi, i just have my miner and i running it ant 756 clock and have a error after 5 min runing. The error is : FutureBit Write error: No space left on device . I plug it direct to my laptop, with stock voltige. Please any help  Thank you ! i get same errors after running them for a while (maybe 1-2 hours) it happens on those i pluged to USB hub and to the one directly to my PSU powered USB3.0 port from PC. ideas whats causing this? Thanks  im investigating this, do the devices stop hashing or they still hash fine with that error? Im pretty sure its related to new work items being sent one right after the other, which happens occasionally. That would cause the UART buffer to fill up, but shouldn't effect the miner (maybe until it gets new work again). Ill try and provide a fix either way in the coming driver update. it looks like this: http://84.200.24.120/write-error.pngmining on litecoinpool right now and had same issue No thats a different error, looks like windows is locking write permissions for some reason. Try launching the exe as admin. |

I'm having an issue getting my Moonlander 2 to be recognized in bfgminer on my Macbook Pro OSX High Sierra 10.13.1.
The Moonlander 2 is recognized in the System Information, but I can't get it to come up in bfgminer using 'auto' or 'all' as a target for the device to add. I'm not really sure what a valid serial port would be. Any suggestions would be great!
Edit: My USB Hub is connected to a monitor, which is then connected via USB-C to my Macbook Pro. So there is some level of indirection to get to the actual USB devices. But my mouse & keyboard work fine so there's that =P
Here's the output from 'ioreg -p IOUSB -w0 -l'
Sigh...did you read any part of my post or FAQ before posting this? Q: My Moonlander 2 is not working with Mac OS 10.13
New security features in Mac OS 10.13 prevent the sililabs UART driver from loading. Until they provide a fix, please use the following workaround:
The workaround is to disable the SIP, installed the driver then enable the SIP.
-Shut down the Mac, start with Cmd-R depressed to boot to the Recovery Partition that will display the System Utilities.
-Open the Terminal and issue the command csrutil status and you will see SIP is enabled. To disable the SIP issue the command csrutil disable and then restart the Mac.
-You can then download and install the latest driver from Silicon Labs, you have the new USB to UART driver installed, and should work with the moonlander now
-Shut down and boot to the System Utilities and issue the command csrutil enable and restart.
-The csrutil disable and csrtil enable can only be issued from the Terminal while booted to Recovery Partition. Yes, this is a PITA but it works. No need to sigh. I 100% did all of those steps. In fact, I did this twice. I did the 2nd installation after running the uninstall.sh script for the driver library (which produces no output when run BTW). plug in miner and go to terminal and do following commands cd /dev ls cu.* you should see a listing for cu.SLAB_USBtoUART if its not there it means the silicon labs driver is still not being loaded by your system |

I see people running these sticks with Rpi s with powered hubs so I wonder... Is this software going to run on armv7 device running kernel 2.6.x. Any maemo freaks here...? That woud be fun...
RPi executable is compiled for armv6 which runs on both amrv6 and armv7 devices. Not sure about really old kernels...that might not even have the UART driver in the kernel, so you would at the very least need to compile the UART driver and load the kernel extension. |
