Nighty Night Don't Let The Trolls Bite Nom Nom Nom

I am having trouble getting my units to run on cgminer for windows.... no usb device found. Works on bitminter though. Any help would be appreciated!

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

I got a 6000mah usb battery from "Anker" with a integrated flashlight, which died after 3-4 months of usage. (battery is fine, just the flashlight isn`t working anymore)
On these grounds i wouldn't stick my usb miners into a very cheap usb hub.

Ah, okay, let me change that. I've found they make good quality hubs. I haven't had any issues with their hubs, and I haven't ever used any of their other products.

And these usb's are 2.0 right? Not 3.0

Again, they're USB 1.1.

Really? Cool! They might even run on the pile of Soekris net4801's I have kicking around.

You think the bulb just went out? And these usb's are 2.0 right? Not 3.0

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.

If you're getting 1% or more errors (on cgminer), with emerald that means temperature
(as you know emerald has no heat sink)
So yeah use that as a rough guide to decide if sapphire needs fans I guess
(unless someone with a sapphire has more specific info about it?)

Of course there's no way of dealing with that in the code other than to stop mining - there's no temperature information or anything to control (i.e. obviously no fan)
... hmm ... external usb fan control ... anyone got any good USB fans that you can control the power levels ... hmm I could see that possibly being useful but also possibly being a can of worms for coding ...

would 1 of these work, with another 7 identical hubs attached, then 7miners in each hub?

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)

can anyone recomend where to buy these in the EU

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

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

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

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

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://bitcointalksearch.org/topic/linux-mining-distro-for-the-raspberry-pi-minepeon-137934

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.
