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 bought two of these from Amazon under the Anker label w/4A power supplies back in July. They have been going 24/7 since. Only problem is the push/push type power switch tends to stick down in hot weather and needs an occasional tap on the unit to free it up. The 4A supplies get quite warm but not hot, so I might think the 3A units underpowered.
