[Announcement] Block Erupter USB

[kano]

Edit: Here's a build of BFGMiner master for use with these.

Note that's a 32-bit build.
Here's a 64-bit one.

which doesn't crash on my 64 bit win7. heh.

ok, i've got mining working now. luke-jr helped me out on IRC.

Now that it's mining away I guess you can get to work stuffing those package, yes?  Or go you need to see how many will mine on your USB stick

they're pre-packed (as you see in my pics) in boxes of ten, so it'll be a lot easier then i thought. yea, i'll get started.

Sorry, was busy getting my kids ready for school

I'd guess the COM numbers didn't match your devices?
You can also use just -S COM1 etc for numbers less than 10
You'll need to look in the device manager for the correct numbers
Yeah the old serial-USB design was rather annoying
(lack of proper working auto on linux or at all on windows and no hotplug)
I'm glad to be rid of it.

Anyway, no big deal, as I said the next version of cgminer will auto detect everything and hotplug (hotplug all but ztex ... and GPUs )
It also tells you what the devices all are ... the full list: AMU, GPU, ICA, BLT, LLT, AVA, CMR, BAJ, BAL, BAS, BAM, BFL, MMQ, ZTX
AMU is of course Asicminer USB (BEU sounds weird )
Just gotta sort out some hotplug issues on windows that I've been working on.

i'll give it a try when the new codes out. thanks all.

Awesome, congrats!  What hash rates are you seeing?

[arklan]

right in line with what kano saw. bout 330 each.

[Luke-Jr]

Here's the build arklan ended up using: Win64 | Win32

[Unacceptable]

For my BFL FPGA I had to find which COM port my unit was using,in my case #3.Go to device manger & look in USB devices,click that device to find COM port #.

Since I installed libwidi driver & 3.1.0 cgminer,the COM port dosen't seem to show now & no longer have to use -S  

Hope that helps  

i'm using 3.1.1, i think... what's this libwidi driver? can use on win7?

It's a non-standard driver. You'll break compatibility with all standard software if you install it.
I hear undoing it is a pain.

Really?? Not sure what you mean,software ??

Yeah,Win7 64 bit.

Oh well,my BFL FPGA seems to work with it,I'll find out if my BFL ASIC works with......someday  

Probably will find out sooner when my Avalon chips arrive & I assemble boards  

I can always do an OS reinstall in about an hour or 2,so no problem for me

 Strange :| My BFL FPGA is instantly recognized when launching CGMiner under Windows YMMV I guess

Yeah,I was using an older version of CGminer then.Had to manually find the port,it was easy though 

The newer version,back about 2 months ago was said to need the weird driver,so................it works,all I care

You running with or without the heatsink (for enough time for things to stabilize)?

What are the temps you are feeling (if you've touched part of the device)?

[arklan]

With heat sink. By themselves, touching the heat sink if burning hot. I put them near a fan,  and no problems. I do not have a temp sensor,  but only warm to the touch in the moving air.

good to see this! will be easy to pair up with my ModMiner rig


Arklan, if you get to try out your hub that will help a lot of people from guessing on that too

The 12 port sitechi handles 3... I haven't  gotten the anker yet. Should be here soon.

I hear undoing it is a pain.

The WinUSB driver is simply a replacement driver that allows USB access to the device instead of blocking it.

This works with the standard mining software called cgminer.

This doesn't work with the rarely used non-standard cgminer clone.

Undoing it is simple but unnecessary.

Any ideas how to run in mac? Thanks.

[Luke-Jr]

BFGMiner can be compiled for Mac if you disable GPU mining, at least.
I think it's part of Homebrew now.

For Linux (Raspberry Pi, Sheevaplug, Guruplug and so on) I tested it here https://bitcointalk.org/index.php?topic=195037.msg2253534#msg2253534

[GreatBug]

Has BitMinter's Java client been tested yet?

While I mine using bfgminer, BitMinter's pretty graphics and 'click on the button to start mining on any OS' ease would be great as an intro to mining for first timers with a USB erupter.

[alibert]

Why would you ran a full blown computer with this? If your electricity bill doesn't matter, you better get a GPU and mine with it. IMHO these devices only make sense with embedded devices like Routers or Sheevaplug/Guruplug/Raspberry Pi/Beagleboard/whatever

[alibert]

Get a GPU then, my 7950 was 230€ and does 550 MH/s

And once you fill up all of your PCIe slots, add a couple of Erupters.

[alibert]

Ebay old computer, get new one for 300€, still better.

Windows is closed source. The windows driver for those devices is closed source. To use PI you only have to plug USB it in and forget it, just get BTC.
