Hi everyone,
I believe I've found the holy grail on USB hubs for miners. Orico makes a 10 port USB 2.0 hub (P10-U2), but never advertises is. I just got in contact with my rep, and will be placing a very large order on them. Cost is going to be significantly lower than any other hub on the list on the front of the page. The PSU is 12v/3a, and is a spitting image of the P10-U3 (which ranges in price from $50 - $65 online).
I should be able to sell them for between $25 - $30 USD including shipping. I am planning on buying at least 100 of them to save a little money on shipping to me (which is likely going to cost about $3 - 5 per unit).
I haven't seen anyone else mention this hub, so I thought I'd speak up. I've had great success with Orico, since they're the ones behind the major favorites like Anker and Satechi.
I told you about this hub. I buy 5 piees for me yesterday and say you about this model.
