Title: unexpected discovery... MacBook Pro powering 7 USB Erupters Post by: bitcoinminer11794591 on November 25, 2013, 10:14:58 PM Thought I'd give it a try before putting them on a USB powered hub through an old windows pc.
Got these beautiful babies (http://www.amazon.co.uk/Daffodil-UHB02-USB-Port-Hub/dp/B0026RYWYU/ref=sr_1_1?ie=UTF8&qid=1385417425&sr=8-1&keywords=daffodil+usb+hub) off amazon.co.uk separated the individual usb ports with a bit of cardboard, stuck an elastic band around them and voila! http://i41.tinypic.com/2jfm6g5.jpg Title: Re: unexpected discovery...

MacBook Pro powering 7 USB Erupters Post by: Xukanik on November 26, 2013, 07:19:55 PM Is it USB 3.0?
I know USB 2.0 standards are 500ma per port but USB 3.0 can go up to all the way up to 5A Seeing that it is a Mac I bet they make each port at least 2.1 Amp to be able to charge the iPad on it. Edit: A lot of USB 2.0 ports have high Amps to enable you to charge your phone etc... Often it is 1 dedicated port on your laptop that will have a lightning bolt on top of it.
