...
Who wants to build the first rack-mounted USB miner? :-)
...
heh...well, i DO i have 429 of them coming my way... (a group buy) the real issue becomes powering them all. even with 12 port hubs, it's 35 of them. good luck finding a circuit in a home to handle that.

Ya-but Arklan...you are not supposed to be powering them without the owner's permission, remember? Smiley

Based on what Luke says I'm pretty iffy about whether I want mine powered up without a heatsink.  And I am pretty particular about the appropriate use of a screwdriver having been a mechanic in the distant past.

I am not in a giant hurry for my particular unit (unlike most others) so i might be able to work out a side-deal with me to fiddle with mine if you can convince me that you have some ability to not immediately destroy it and some ability to replace it if you do, I'm as curious as anyone about how a 'mini-rack' of these things behave...but no-where near curious enough to blow $1500 on the experiment.  Certainly not until I see if _anyone_ manages to get an order in to to the-cat and get a working miner for their troubles.  e-mail me if you have interest in such an experiment and need for my single measly mining stick.



that was a joke, man. Cheesy

Even if you could power all of them, note USB only supports up to 127 devices on a single host PC... and only 5 USB hubs chained - including the internal 2 hubs in your "12-port hub".

But... is it 127 devices per computer or per Bus?

Code:
xxx@xxx-desktop:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 05e3:0716 Genesys Logic, Inc. USB 2.0 Multislot Card Reader/Writer
Bus 008 Device 002: ID 046d:c062 Logitech, Inc.
xxx@xxx-desktop:~$

Does this mean this computer can have ~8*127 USB devices?

My ASICMINER USB Erupter showed up about an hour ago.
Been playing with the Icarus timing settings still not quite got it right yet.

Obviously yes I'm getting around 300MH/s out of it.

Currently best settings are for anyone wondering while I sort it out:
 --icarus-options 115200:2:1 --icarus-timing short

Edit: the USB chip is: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

NOW SHIPPING!! GET YOUR ORDERS IN!!

Looks like they built that batch by hand. Looks like they held the soldering iron on the board a little too long. Got a little flux they didn't clean up on R2 there as well.

While these are neat, and I'd really love to have one. 1.99BTC is still a bit high to ask of a USB device I think. Especially in the initial development stages where they have problems with heat.

I'll buy these all day for 1-1.5 btc, in my opinion this is a perfect price point for profitability and would increase demand, due to the high price its obvious there is less sales that their could be.  The volume of sales will compensate for the price cut.  

Id however like to see a rev.2 of this or a new product that is the size of a roku or apple TV box with up to a GH/s.  

I am a shareholder in asicminer and do agree that this product or a v.2 of this should be slightly lower to increase demand and profitability for asicminer

I live in Brazil and I'm interested in buying one or up to 4 of those. I'm still mining with a GPU in here.

There is an internation buy in for them here https://bitcointalk.org/index.php?topic=201577.0

Update: I let it run for a few hours without any external cooling besides my house's air conditioning. It basically went to all hardware errors. The good news is, within a few minutes of turning the fan on, it recovered to full hashrate with no hardware errors. Smiley

Does this mean running it without the heatsink as well?

The Emeralds didn't have a heatsink. The original context was someone asking why it needed one Wink

yes. each one of these will essentially max out the power of a traditional USB port (usually 500mA). A powered port is more reliable and sometimes pushes a higher mA if needed.

even so, batch 1 is reported to run at nearly 560mA according to the OP.

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe
No longer a wannabe - now an ASIC owner!
