i still don't understand why the price is so high
1 chip + 1 mini pcb + one usb connector = 2tbc, really?

 Look at it another way, where else are you going to get 300MH/s running on a USB stick @ ~500mA ?

it would have been much better if they were priced 0.50-1 btc, much honest price...

Why does it have to be honest?

should i use a hub with external power? I will only have 2 USB on.
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.

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

Ah, good to know.  Thanks!  Smiley

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://bitcointalksearch.org/topic/closed-group-buy-batch-one-asicminer-block-erupter-usb-international-201577

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

Cant warrant spending that for 300M/hs. Or is it just me?

Can you warrant spending that on COOL?

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.
