Does the Block Erupter require a USB driver? I'm running Win7 x64. Where does one download the required driver for it? Thanks!
I think it should be autodetected.

What? We are way over the 15 days and way way over the 20 days promised for delivery. looks like you lot wont even make the change to 12.5m difficulty in 10 days!

How long do you have to be late before we can flame you as vapourware ala BFL ?

Our group buy has 100 incoming already, already in Germany.

The rest is coming over now, mine included :p

The multimeter method will give you the exact current draw.
But the multimeter won't account for power supply inefficiencies, CPU usage, and lots of other stuff.

No point in being precise if you aren't accurate.  Cool

Of course it is worthwhile as an academic exercise.  I'm just pointing out that if you are going to be making profitability calculations that the current draw from the USB port to the miner isn't the thing you want.

Anyone find a suitable USB hub that is powered and has enough spacing to allow for adequate cooling?

I found this one but the power supply only provides 2A @ 5V, meaning if each port pulls 500mA you'd only have enough power to run 4 USB Block Eruptors:
http://www.satechi.net/index.php/satechi-12-port-usb-hub-with-power-adapter-2-control-switches

Also saw this one, but could find no details as to its power supply specs:

Last this one, but the side ports don't seem useable. Also, no power supply specs either:
http://www.digitalinnovations.com/connect-charge-7-port-hub.html

I don't know half of you half as well as I should like; and I like less than half of you half as well as you deserve.

I was figuring they wanted to know the current draw at 5V to determine how many can by powered on a single hub, in which case, it is accurate and precise. Smiley

How much power is drawn from the wall is another matter.

I'm going to use an Anker 10 port hub.  4A @ 12V.  They make good quality stuff.

That does look promising, but odd that it puts out 12V, isn't USB spec'ed at 5V?

There will be internal voltage regulation down to 5V.

Is it possible to mine using an android device? Like using and micro usb to regular usb adapter and using a powered hub

A Raspberry Pi can do it. It's linux, not android, but it's still an ARM CPU. It's a nice way to keep power consumption as low as possible. Check it out here: https://bitcointalk.org/index.php?topic=137934.0

So, I'd be safe to run 5 on this hub right?  You guys think we need to blow a fan on 'em?

I saw at least one person over in Arklan's group buy who claims that hub will run 10 sticks. Arklan said he's running 9 sticks in one (he didn't try 10).
I have a fan moving some air over my sticks. I doubt that it's really necessary, but it makes me feel better so I do it anyway.

The US/Canada group buy has confirmed that this hub can drive 10 Erupter USB's

Anker 10 port USB hub -- http://www.amazon.com/gp/product/B005NGQWL2/

Going to run 9 Erupters in the first 9 slot, and stick a USB fan in slot 10 'fo shiggles giving the Erupters some airflow.

ARCTIC Breeze Mobile USB-Powered 92mm Portable Fan -- http://www.amazon.com/gp/product/B003XN24GY/

I placed an order for a Mondohub 28 port (http://www.amazon.com/gp/product/B0074024XU/) but I've been informed it cannot drive more than 5 Erupters despite the specs on Manhattan's site saying it gives 500ma to each port (http://www.mondohub.com/hub_overview.php)

confirming anker 10 port hub handles 9 no problem, and airflow is a GOOD idea.

Yep, 4A@12V is (without any losses) approx 10A@5V, so should be good to run 20 devices, if it had that many ports Smiley

Depends on the device, but in general, yes. You need a linux in a chroot environment. Commands are the same as for Raspberry Pi or Sheevaplug, its just a bit slower (for me I/O are very slow, because of my slow minisd card). Some devices may have problems serving as USB host. Devices like this might help http://dx.com/p/ug802-android-4-0-dual-core-network-multi-media-player-w-wi-fi-hdmi-tf-black-1gb-ram-4gb-153223

can anyone recomend where to buy these in the EU
