if my goal is 4.5mh per stick, do I need more than 1.0 amp per port?

Yes, more like 2A+ per port to be sure.
Mine at 5Mh draw 2.4 amps each.
These units are very efficient at 3.7Mh approx 5 watts
but power draw increased exponentially with Mh increase.

What kind of amps at 3.7Mh?

I'm trying to determine if I can get away with 1 amp or not as the costs associated to go to 2amp USB hubs is quite a big jump in price.

1A is about 3.5-3.8. You have to remember though, just like any PSU you can't expect reliable power delivery if your running it at 100%. Just like you can't really run a PC/GPU system that draws 500 watts with a 500 watt PSU.

You can try 636, 648 or 660 for the freqency.
648 might be best, if you get it resetting or too many errors
drop down to 636, try higher 660 and see what you get?
Some variables here on the hub and actual power that can
be supplied to each usb port. Have fun testing.

I think you should be around 5w to get 3.7Mh.
5watts at 5vdc = 1 amp per usb miner power draw.

so if I shoot for 3.5Mh that would in theory be just under 1amp.

Do you or anyone have recommended settings for that? I hope to have my batch 1 miners soon

5watts at 5vdc = 1 amp per usb miner power draw.
Multiply by miners you are intending on running for total current required.

Hello all,

Can someone suggest if the following USB HUB is a good buy to run multiple moonlander 2 USB miners with its optimum performance? appreciate your quick help on this,

https://www.amazon.com/Sipolar-Bitcoin-Mining-Black-Industrial/dp/B01K4EHLBW/ref=sr_1_5?s=electronics&ie=UTF8&qid=1513632237&sr=1-5&keywords=sipolar+USB+2.0+hub

Thank you.

Don't think it's got enough power per port...

"5V/650mA sufficient current per port"

Yep a lack of juice per port

Any good suggestions that are available on Amazon? Thanks.

2.1 amps per port vs .650 amps per port

so I have three miners on a usb hub, one was running fine all by itself but as soon as i connect the other two it says ASIC stopped hashing, attempting to restart..what could be my problem? I tried to add devices but when i go into the "add devices" option i use the "all" selection and when i had one miner even on the hub it connected and worked..so why can't they all connect when I click "all"
(p.s. when they are all connected they come up as MLD0 MLD1 MLD2)
thanks
(p.s.s) (im not sure how to search serial ports since it is a hub..or is that the number on the moonlander..thanks
edit now it is telling me device is not configured...how do i configure my devices

The new software has been running great so far no issues.
Here are some photos of my modified 10 port hub, wire soldered on power
tracks to top of caps solder points.
With the wire mod and 5vdc @ 10amp supply can get 5Mh per unit (Freq=876, D=1024)

Tripp-Lite 10 port hub:

Modified power rails:

Hardwired to circuit board:

25Mh, x5 usb miner hashrate:

Thinking about it, I'm not sure if the new driver I've been trying to download is the new one. I've been doing it through my RPi's terminal, and both the new driver and old are named the exact same thing... so maybe it has just been downloading the same thing over and over again? Any ideas on how to specify the new driver?

You should see build number 38-g106390a9 if you are running latest version at the top. Just download the latest release binary on my releases page and copy it over to your pi...

This is my current solution.

added an external power supply 5V 10A to the USB hub (directly connected to the USB ports without any chip limitations

Exactly what I am going to try. Waiting on a cheap 10 port USB hub to be delivered, have 12A 5v supply so should be able to power 6x Moonlanders

12A already is a lot .. please check temperature on your hub and cables then

it already gets warm on my 3 devices!
i just bought an overpowered PSU for stability reasons.

Would be cool if you share your experience

Using a Gridseed it is possible to change and display the frequency in the "Manage devices" menu. Would be nice if it would be possible with the Moonlanders as well.

3x Moonlander 2 running at 4.3 mh/s and a cheap USB fan blowing to the small heatsinks (just to be sure).
Wall to the fans on the back got about 2-3cm distance so the air can flow just fine.

All connected to Raspberry 2 - works like a charm!
