I put the SCRIPTA distro on my RasPi and got it preconfigured as much as I could, but I'm hearing there are issues with chaining large USB hubs together. In other words, if you need more than two hubs you might want to set up another Pi.
The Pi can only handle hubs 2 levels deep. As far as I can tell, the max number of ports at a given level is 7. So, if you have a single level 7 port hub, you can plug 7 into that, and have 49 miners on one Pi USB port. The Pi has 2 USB ports, so, in theory, you can put up to 98 miners on one Pi.
When USB 1.1 was released, and even 2.0, the maximum devices of 127 seemed laughable. (Who would ever need more than 640KB of RAM?!)
I was never able to realize why someone would find it useful to have 127 slow devices connected in this way. Since I can readily envision a large Gridseed farm, it amazes me this max is finally being realized in something useful besides research!
I will have the first half of the shipment arriving this monday. However the cords I ordered which originally I was not going to include but with the recent price cut shortly after my group buy closed I decided to include them to help compensate. I want everyone who ordered to know that my group buy did not profit me a single penny and has actually cost me a rather large sum of my own personal funds which is not including shipping costs. I am doing everything to make it right for you guys which is why I was able to offer such a cheap price prior to the price cut. I was not informed of the recent price cuts and feel slightly cheated myself.
If you would like your units shipped today without power cords send a email with your order ID # to
info@bitcoinminerz.com for in store credit redemption on the cost of the cords and a in store coupon as well on the few over stock units from refunds I have had to submit. My live chat will be online from now until about 1:30pm EST which I estimate is when they arrive so you will have to contact me before then.
My second half of the 300 ordered will be coming in by about thurs-friday as well. If I decide to do another group buy I have ironed out all the kinks and issues which caused delayed times with this group buy. I will be sending out each shipment in the order they were received.
My next thing regarding controllers for the raspberry PI. I will not be able to get any wholesale units in a reasonable time limit for the ones who have a free wibox in their order and do not need a RPI please contact me as I will offer reimbursement. The RPi will ship seperate from the gridseeds.
