Re: [ANN] FutureBit MoonLander: A Modern and Efficient Scrypt USB Stick Miner!

Well I got the SuperBpag hub.
First I connected it to the RPi2 and set the freq at 160. The Moonlander ran for about 3 hrs at roughly 400 kh/s. Then is started drifting out and finally going dead. I have tried all sorts of freq and adjustments and it will not run very long before slowing down and then going dead. I have adjusted the diff manually, tired several pools, (LiteCoinPool, LTCRabbit and Clevermining) also made sure there was lots of air from two different fans blowing over it.
Just cannot keep them running solid for more than a couple hours to sometimes even 10 mins before it goes dead.

I then tried on the Cubieboard with the same results. Then I tested on a PC with the same issue.

Very strange.

Any suggestions to keep them live??

I ordered one of these it will be here tomorrow. I will let you know how it works on the custom images for the RPi2 and A10 Cubieboard with Minera that CrazyGuy setup.

I believe my HUB isn't performing to what it says. I got the superbpag USB 3.0 Superspeed HUB,http://www.amazon.com/gp/product/B00W4X3DAA?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00, and when I plug a moonlander in, it wont read on bfgminer. My computer will give the error "usb device not recognized the item has malfunctioned", I thought I received a destroyed miner, but when I connected my other two, it gave me the same error. I connected the miners directly into the computer and they all work.

Yet I'm having an issue of the speeds slowly decreasing and bfgminer 5.4 declaring it "SICK. Does anyone know how I can fix this? Should I increase the intensity?

Also to get multiple miners working at one time, should I run two instances of bfgminer each with its own config or can I put in the config to use two login information?

This is the hub I recommend. http://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM/ref=pd_sim_sbs_147_1?ie=UTF8&dpID=41LaxmqTREL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0FW4KH14FP92J3MHA2XF

It has an internal really well constructed Powersupply, and is the only hub I found that can handle all 7 ports running full speed. The on you linked probably has an external crappy brick PSU which is probably not good enough.

For the "Sick" issue it probably means you have the difficulty set too high...so it takes forever for the stick to submit a share, so bfgminer "thinks" its sick. Remember these are low powered devices and most pools think you are connecting high speed ASICs to them and have stock high difficulties. Make sure you are using vardiff with low initial diff, or forcing a diff of under 100.

16 diff per stick is a good starting point. This will give a share every second or so.
