https://bitcointalk.org/index.php?topic=190731.msg2748156#msg2748156 BKKCoins on revision to K1. Check your hubs gentlemen. I haven't updated the K1 files yet. The new board revision will use the 2G02 but it's not pin compatible so you can't place that on the old board.
Here's a brief list of changes I'm doing for the K1:
- replace NOR gate with DUAL NOR gate
- add Schmitt inverter package
- chg PIC to QFN
- add thermistor for temperature sensing
- add 2 holes for mounting a heat sink
- Make both LEDs flashable (tied to PIC pins)
- make I2C non-thru hole SMD header type pads
- use 2mm board thickness for USB compatibility
- specify an alternate reg and inductor allowing 3A power (not for USB 2.0 ports)
I'm part way thru this now but have been sidetracked today by work on the web store (which is up now but not tested yet). Yay! the revision requires USB 3.0 port? is that the deal with K1 PCB re-design? |

I've started on a table over the hubs that were mentioned or look promising. See OP. If anyone had successful experience with any other hubs, please mention them here.
I'm having good results with the Cambrionix A6 49 port 2.0 Hub on Windows7. Will update once I've tested it on BeagleBone Black. It's waaaaaay too expensive to buy new, but I scored a used one for $200. Currently running perfect with 33 Erupters, 16 more on the way. Hoping my Sparkle Power Supply can drive all 49! $200 for it is a steal!!!! i'm getting quotes of over $1000. ordered me one to help me with Eligius branding and testing of USB Miners sold on their pool's website. should arrive tomorrow |

We should be (as far as I know of) the first group to have a non-BFL reference design up and running, so I'm pretty happy will progress thus far.
That's awesome!! |

MrTeal,
Did you receive the samples?
my sample chips shipped out yesterday |
|
|
|
Will be hoping on-board the Canary ASIC express for at least one.
*And another USB hub if you still have those available?
Ankers are back in stock on amazon... i am out of them atm. |

Look at the 10-port Apple style one (it's in the "size" selection on the same page as other product). Seems to be more what you're describing. (is $57.99 instead of $49.99 though)
(ETA: only 20 "Apple style" ones in-stock, though...!)
"connected devices should not exceed a combined current of 7A." (note isn't made on the 9+1 hub, though that doesn't necessarily mean the limitation doesn't exist on the 9 non-charging ports)
USB3 hubs should provide 900mA per design. For 10 ports that not even with a 5A psu possible even with the power given by the usb-port the hub is connected to. They probably think that no one will max out the power. so how many OC'ed Klondike 1s can run in one of these?  it does handle 10 ASICMiner USBs just fine. |

ordered 1 to test out... check this pic: same pic can also be found this thread: https://bitcointalk.org/index.php?topic=256999.msg2741666#msg2741666 |

http://www.amazon.com/gp/product/B005NGQWL2/is it me or is the Anker 10 port black hub changed? it went out of stock a while back on amazon (probably due to all you miners here LOL) now it's back, but it's listed as a 9 port + 1 charging and it's now 5A, not 4A... anyone spot the change or am I hallucinating due to the lack of sleep?
