I will report back my experiences as follows:

I have 3 MLDs, running on a Pi - Linux from a mac.  I had a 7-port USDB 3.0 Plugable and it never worked smoothly.

I got very curious as to identify why that was the case and eliminated gradually different causes for the instability of the miners - including reinstalling bfg on the raspi SD card, switching the power inlet to the USB hub, adding fans etc. Finally I caved in and got an new USB hub, this time a 10-port Sipolar (as recommended here several times). I also got a secondary desktop fan and disconnected the noisier small fans on the stick.  

I can say that now my miners have been running completely stable, clocked at 800Hz and with the external fan quietly blowing on them generating around 4.5 Mh/s each with a temp in the mid 50C. So, in my case the instability was caused by a combination of not enough power from the hub combined with lack of cooling.

Thus, even others seem to have had no problems with the Plugable USB hub, I would not recommend it, but would recommend forking out the slightly higher prices of the Sipolar hubs. You can get them from either eyeboot or aliexpress (if you're willing to risk it).

Cheers!

You need to reinstall the USB - UART Drivers as it seems as though they were lost/corrupted, etc..

Lay of the dope and you would have known that. lol

Yea, just windows updates breaking stuff as usual, silicon labs has posted new drivers that resolve the issue.

for the record, it took a lot more messing around with the driver situation after this windows update than just downloading that one file. needed that file, but turns out my laptop wasn't reading one of my usb hubs, thus not reading those 2 ML's.

These have been working great for me on litecoinpool.org, mine have been going for over a week now without any issues. I was thinking about trying out prohashing.com, anyone mining there with these? What do I need to enter in the start_moonlander2 file for prohashing (I have three sticks if that matters re: difficulty)? Thanks as always 

Most pools have a sample config file on their getting started page. Don't use prohashing with only 3 moonlander's, their min diff is 16384 way to high, plus they charge 5% in fee's as well as a 1% withdrawal fee, also not very dependable connection wise.  If you are looking for an auto exchange profit switching multipool try dutch-mining or hash-for-coins, both charge 4% in fee's and coin minimum withdrawal fee's.  If you are looking for a good profit switching multipool where you keep the coins and exchange yourself, try multipool or dutch-mining (you can turn off the auto exchange), both are 2% fee's, free/minimal withdrawal fee's, and you keep your Doge.  If you are looking for a different Litecoin pool, try Via BTC, 2% fee for PPS 1% for PPLN, lower withdrawal min, and you keep your Doge.  BTW litecoinpool.org charges zero fees but keeps the Doge you merge mine thus charging an actual rate of 1.5-3% in fee's depending on the price of Doge/LTC

I don't know the brand but we can do some math.
24 volts X 4 amps = 96 watts total available power.
96 watts divided by 5 volts = 19.2 total amps at 5 volts.
An ML2 needs between 2.5 and 3 amps.
So at 2.5 amps each, it can power 7 ML2s
At 3 amps each, it can power 6 ML2s

Hope that helps.

I had a fan fail today,    anyone have some part numbers or links to one I can buy for cheap from a supply store

I found an eBay,  SUNON KD0502PFB3-8 5V 0.3W 25x25x10mm 25mm 2510 Mini DC Cooling Fan   for  $4

just making sure there's not a better option out there

and confirming it's a 25mmx25mm by 10mm height

You're right.  The fans are this dimension (25*25*10mm) And it is 5V.

They're also available here: https://www.aliexpress.com/item/3d-printer-part-fan-2510-2pins-25mm-25x25-x10-mm-2-5cm-graphics-card-fan-DC/32810831724.html?spm=a2g0s.9042311.0.0.67a74c4d9mHuRe

I got some of these, they are not any more or less noisy than the stock fans. Actually the more quiet and effective solution is to buy a strong silent USB fan (the round tube ones) and use those instead of the stock fans. But YMMV.

Can anyone give me some detailed instructions please on the following:

I have 6 MLDs. They're all currently mining LTC in litecoinpool. But I want to try and mine another coin/token-maybe Digibyte or another Scrypt one in hash-to-coins. 
I am running my miners through a raspi 3 on linux. But I'm not advanced user. Can anyone share some tips and instructions as to how I need to go about setting this up.

Same process as you used to get them mining LTC - setup a wallet, create an address, choose a pool, change your existing pool address and wallet with the new ones...

Hello everyone

I mine with my raspberry pi 3b + and 2 asic usb gekko 2pac or moonlander 2 powered by a usb hub

The gekko with CGminer and the moonlander with bfg miner.

it works pretty well with 1 key connected, but not when I have 2 on the hub ...

I would like to run the 2 miners at once but this causes:

cg mine mine correctly with the gekko but throws me usb init failed (du moonlander)
bfg miner hasrate hut quickly to get to 0 ...

Is it feasible to throw both minors at once without problems?

My problem is he has to manage who seeks to activate the moonlander? (how to disable the moonlander?) (or mine in dual?)

below my bat:

cd / home / pi / git / vthoang / cgminer
sudo ./cgminer -o stratum + tcp: // pool. -u -gekko-2pac-freq 100

./bfgminer --scrypt -o stratum + tcp: // pool -u -p 1, d = 128 -S / dev / USB0 --set MLD: clock = 600


Thank you for your answers

Hey ther moonpeeps! so I'm getting an error on one of my moonlander2s. (timestamp) futureBit write error: Permission denied over and over again, any ideas what the issue is? windows 10, bfgminer 5.4.2.38-gl06380a99, all other moonlanders are hashing away just fine, its just the one stick so far.

Thank you for your answers

I think gekkoscience cgminer does some non-nice things on the uart ports when it’s scanning/setting up the miners, which corrupts the Moonlanders, so they currently don’t play nice together. I’ll see if I can talk with the dev and sort it out.

Many Antminer L3+ were sold in the last few months, so I saw difficulty almost double. You can try multipool.us if you want to try a multi coin pool that will switch automatically for you. Even if you have 6 MLDs, I don't think you'll recoup your investment ever, especially with cost of electricity. Do it for fun and leave it at that.

Never say that in crypto world Wink People that bought my original Moonlander in 2015 when LTC was $2 weren’t making anything either in terms of dollars, but would have mined nearly 2 LTC total from 2015-2017, which even at $70 LTC price would have more than 4x the intial $40 cost.

I think you're probably right. I could have bought more LTC than I will earn with the MLDs over the next decade for the same price. But really that isn't the entire point. I am interested in understanding mining, so its just like another hobby. But at the same time, trying to mine a much cheaper coin (like DGB) may turn out favourable if it increases in value.

Thus my second question: How do I split, say 3 miners to mine LTC in litecoinpool and then another 3 miners to mine Digibyte in multipool or hash-to-coins? I am not a big expert. Basically this exercise was the first time I have started using sudo commands ever. So if you know how to divide the miners up, pls ELI5.

Using raspi3, Linux access through a mac.
