sorry had a bad night thanks for the response, same architecture as a pi really was hoping some pi users were about
here's a raspi user, currently driving 3 moonlander2 and an old rpi2 for bfgminer off a 'rather pricey' and very powerful USB hub at 796, above they become unstable in a rather unpredictable way. i suspect the usb WLAN dongle i have to use in my setup as a part of the problem - i think i read about USB bus saturation being a possible problem SOMEWHERE, but didn't debug in this direction any further yet... anyways, the basic setup worked like a breeze. plug your MLDs in, run bfgminer as described in a lot of places, watch your MLDs have fun. however 9 more moonlanders are on their way to me, and i am eager to see if i can drive all i then have reliably with a bunch of hubs and one rpi3, which will eliminate the need of a seperate dongle. considering that could actually fail, i have a bunch of rpi2 around, and a bananapi routerboard (BPI-R1). i'm kinda sure i'll find a way to make it work reliably, somehow. sweet, i might be slightly better off as the odroid is usb 3, I'm looking at this hub: https://www.scan.co.uk/products/icybox-ib-ac6702-7-port-usb-30-hub-7-charging-ports-led-amp-digital-display?v=cI'm worried about this line though: The USB 3.0 ports on this hub are special because all of them can load any connected mobile devices with up to 2.4 A. The intelligent chipset determines the best charging rate for all models. [edit] found some cheaper hubs from a company called orico claim 36 watt on a 10 port, 12v 3a psu There's a better deal... 13 port ones... 60W 2.1 A per port. Fits 7 MLDs at 700MHz

Fits 7 MLDs at 700MHz damn I already ordered the 10 port, oh well only got 5 of these on the way atm ... shameless self-reply: the 3 ASICs run stable at 900, when i point a fan at them. it's not USB bus saturation, it's temperature. waiting for the rest to arrive today, hopefully.
do these little guys get quite hot then? the hub i ordered has an Aluminium body hopefully help with heat dissipation

BTW; @jstefanop: What i'd love to see in BFGminer / the MLD's if possible; a way to identify them. BFG sets them up as MLD 0, MLD 1, MLD 2.... etc. But there's no way of telling (as far as i am aware of) to figure out which stick is MLD 0 or MLD 1 etc. Troubleshooting can be made so much simpler with unique ID's. After a reboot, the ID's get swapped now so MLD 0 could then be MLD 2 etc. I know that my gridseed dual miners had unique ID's, so if you plugged them in 1 at a time, you could make a note of which ID that miner had and if there ever was a problem you knew exactly which miner to fix.
Moonlanders have UIDs as well. Just press "M" while its running, then select the device number you want, and it will show its ID under serial number. You can then match the last couple digits to the actual serial number sticker on each device. Hehe, if it was that easy: I regularly have that bfgminer fails to recognise the type of device and thereby extract the serial number, BUT it still hashes away! I also used the bfgminer debug mode to look in more detail and see it happens when the usb/com ports are pinged. It finds the port but not what is attached to it. Still it starts hashing, without knowing what is attached to it. Next update will also have enable/disable functions implemented, so that will be another way to quickly check which is which since toggling enable/disable will cause the LEDs to flash.
I have something weird: I have one MLD flashing red LED but it doesn't show up in bfgminer!! That means it kept hashing but probably got disconnected from bfgminer. It is not in bfgminer anymore, bfgminer is one MLD short. I don't know when it happened or how it happened. I am not sure exactly which physical device it is. Later today I will just restart bfgminer and it probably will get connected again.

Hi I have 6 fb ml2 powered by a block erupter hub. I can never get all 6 to mine. One always seems to drop to khs. Does anyone no why this is? They all work separately but a different one will fail each time they all mine together. Also is there a way to program bfg miner on Linux to restart a miner if it drops below a hash-rate as it is not auto restarting. I have tried lowering the frequency but one will still start to drop hash rate after a while. Thanks

Probably not enough power per usb port. Needs 2 amp minimum per port! ...

do these little guys get quite hot then? the hub i ordered has an Aluminium body hopefully help with heat dissipation The 10 port 36watt will NOT be able to feed all 5 (you ordered 5, right?) MLD's. Sorry to dissapoint you but for most hubs these MLD's are just too hungry. Especially if you want to crank them up for a higher hashrate. Mine have been hashing 21 hours at this moment, temps (with the fans on them) are between 32-35 and one runs between 43-47 degrees celsius. They are running at 900mhz. Amp draw varies between 2.25-2.4 amps. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fmyalbum.com%2Fphoto%2FrENL5gfpUCI9%2F360.jpg&t=665&c=nMyG9FoUi3fL-w) ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fmyalbum.com%2Fphoto%2FiV2K5OB7EYpg%2F360.jpg&t=665&c=HjyUxKQwRMz4Og) I'm running them from this hub: http://www.sipolar.com/page172.html?product_id=18&product_category=17And will run maximum of 8 mld's on that. The hub is rated for 2.1 amp per port so i'm already stretching that a bit, but the hub itself is fan cooled as well and by only using 8 ports instead of 10 i'm guesstimating it'll work out. Hope that'll help you and others with their setups. Also, when taking temps, be sure to measure at multiple points on the heatsink, the temps will vary greatly depending on where on the heatsink you are measuring and i feel that the slanted 'teeth' on the heatsink enable for some false readings when not being careful when measuring. I just rebooted my bfgminer so i could turn up the voltage on 1 of the MLD's, they now all are running very nicely at 900mhz and hw error rate for all 3 now is about .5%! (the one i adjusted was almost 6%)

Thanks! That board is your problem, it only provides 500ma per usb port. As you can see in my post above, the MLD's easily go over 2 amps!

oops brain fart went n divided the watts by the ports instead of dividing it by 12 first smh ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) I've got some 12v 5 amp supplies kicking around I'll give one of those a go if it doesn't have an amperage input level should be ok, as far as i understand it it should just pull what it needs or is capable of handling. probably should've gone for the one from scan instead but this one claimed it was suitable for usb miners if only I could do maths in the morning worse case scenario it melts and so do the sticks lol

The one you recommend looks great but it'll take 20 to 40 days to get to me. I'm tempted to order the other one that claims 2.4a per port but I'm still concerned by that intelligent charge circuit thing, got a few more days hopefully I can find a UK retailer that does a comparable one to your recommendation

This one only has 2.1 amp max per port 10 amp total, still not going to cut it. These Moonlanders need at least 2.5 amps apiece.
