Ugh the litecoin unable to release order bug is back.

There is a buy order for 0.02509990 in the litecoin order book and it's impossible to sell into it.  If it gets fixed by the time you read this you can tell it was an issues in the history because the price flatlines for awhile.

Kumala, is there any way you can monitor for this so you can fix it manually.  I get that the cause of the bug might not be clear so it's difficult to fix but it's very obvious when this happens and I would think there would be a ton of errors on your side.

If you compile minerd from here https://github.com/gridseed/usb-miner/tree/master/software/cpuminer it will scrypt mine from a computer without the SHA256 core enabled it.  I tried it last night on a linux box and it worked fine, though my hashrate wasn't any better than with the controllers and my computer didn't like when I reset the power on the miners (it acted like it ran out of usb tty connection so wouldn't open new ones).  I'll probably just stick with the controller but if you need something that will scrypt mine without wasting power that's an option.

The raspberry pi binary just dropped on here https://litecointalk.org/index.php?topic=9908.msg132325#msg132325 via Chirale

Yeah I reached out to both of them when I first got my units and just today DrFranz PMed me back on the litecoin board.  Apparently they are going to release the minerd binary and patch soon to have it run on a raspberry pi directly.  If that's the case that would work perfectly for me as I already have a few raspberry pi boxes that I used to run BFL hardware.

My plan was to upload the compiled cgminer from http://www.wiibox.net/down/v2.0.1.zip into a linux distro running on the same MIPS hardware.  No clue if that'll work but worth a try.  This way I can script cgminer directly instead of dealing with these terrible controller interfaces.

Anyone found a manageable way to keep these things running?

I have mine monitored and I get an alert if they stop mining but when I'm at work I'm unable to do the power cycling required to get them back up they just site there unused.

As a temporary fix I bought one of these, http://www.amazon.com/gp/product/B007SP64SM/, to setup an automated power cycle.  I also ordered additional controller hardware (http://www.amazon.com/gp/product/B005VEJ3GM/) and I'm hoping I can install openwrt on it and get the cgminer from wiibox running directly on it so I can have better control of the mining (separate frequencies per miner, better monitoring, multiple pools, etc).

I'll let you guys know if I have any success with that.

FWIW the colors on my power cables didn't match the PDF so if you have a multimeter I would use it to match up the bare wires to the plug.

If you were using the gridseed cpuminer git repos you should edit the source to have it print on read timeouts (https://github.com/gridseed/cpuminer/blob/master/gc3355.h#L288).  When I attempted to hook up my units to a linux box they looked like they were getting work from the normal output but in the end the code was just hitting this read timeout over and over again.

Anyone know how to fix the 10 minute restart issue.  Someone earlier mentioned they had a problem where the units would shutdown in 10 minutes if one of them wasn't hashing.  Seem like the timeout is too low as mine are stuck doing this now and I'm at work so can't restart them and bring them up one at a time.

Graph of what this does to my hash rate, you can see it drop back down every 10 minutes or so and not be able to work it's way out on its own.

How did you get dual mode enabled.  I thought the controller that came with the box didn't support it.


True, the difficulty is going up quick which is why I was hoping to get some btc mining out of it before it wouldn't justify the electricity cost.

Also someone asked for the power supply model earlier, that one is SPD-360W

The heat sink will be gold color instead of red or silver.

I tried building cgminer on my ubuntu box from https://github.com/gridseed/cgminer-3.1.1-GC3355-SV but was unable to get it to recognize the miners.  I got the included controller working though so didn't try very hard.

Here you go though it's pretty basic.  No SD card, just a power, network and usb port.  The controller is listening on SSH port but no one knows the user/pass.

If you can't read it in the picture it says "Costumed by LIGHTNINGASIC" which I got a chuckle from.

There is a 220v -> 110v black switch on the side of the unit.  This got me too, no idea why they don't switch it for you before shipping to the states.

There is a dropdown where you select the hash rate, from 600 to 900.  This came with the bundled controller.

I'm not sure how to go up to 500 Kh/s, I'm almost wondering if that was a temporary thing or if that was sustained for the user that posted screenshots.  My max is around 3600 Kh/s which I can get on both my units at 850 MHz.  If I set to 900 MHz it goes slower (around 2800 Kh/s) and if I leave it at 600 MHz it is well below the advertised rate (2000 Kh/s or so).

I have a raspberry pi so tried to see if the cgminer binary from this would run on it.  The problem is that the binary is built for MIPS32 hardware not ARM hardware like the raspberry pi.  So unfortunately it won't run on there but it might be possible to get it to run on other MIPS32 hardware (for example the linksys routers that can be flashed with openwrt are MIPS if I remember correctly).

I finally got my controllers back up and running.  Many thanks to eightcylinders for the help.  The trick was for some reason starting the controller with all miners plugged in would cause the controller to never start mining and they would be stuck either "offline" or "online" but with 0Kh/s.  I heard in another thread the unit will restart itself every 10 minutes if no work gets done so it may have been in an endless cycle of being unable to get started.  After starting up the controller I plugged in one miner and made sure it started hashing after a couple minutes then I could plug 4 more in, then after they started hashing I could plug in the remaining 5.

As for settings and hash rates I was able to get around 3600 Kh/s on each unit.  This is at the 850 MHz clock speed.  I found going to 900 MHz would cause it to be below 3000 Kh/s instead of speeding it up so 850 seems to also be the sweet spot for me.  I'm on multipool.us multiport and it also reports roughly the same hash rate I'm seeing locally.

Hmm, not working for me.  Thanks for digging that up though, downloaded that link and found the modified cgminer in there.  Might play around with that some if it will run on my linux box or raspberry pi.

I'll post the status of my rig when I get home from work.  Before then though does anyone know what the official method of getting support is.  I PMed asiabtc and sent Jack an email but haven't heard anything back yet.  Just wondering if that's the official channel to go through.
