Re: Now that usb sticks are being sold by sidehack here is a new usb hub thread.
As I discovered with my 7-port, 60W charging hub from Plugable -- pop it open and look at how the power is distributed.
On the Plugable, it takes 12vdc in and has 3 buck regulators taking that down to 5v for the USB plugs. That said... 1 regulator feeds ports 1 & 2, the 2nd regulator feeds ports 3 & 4, the 3rd feeds ports 5-7. See where this is going?
After futzing around with 2x of the 2PAC's along with an original Compac just plugging them in 1-2-3 I was unable to run all 3 at decent speed without at least 1 stick dropping out. Looked inside the hub and found ^^ so...
Put one 2PAC on port-2, the other on port-4 and the Compac on port-6 so each stick has it's own 5v regulator. Now the Compac is back up to its usual 318.75MHz and the 2PACs are running175MHz 225MHz giving a total of 65-70ish GHs pointed at solo.kano.org. Lovin' it

is this the one you're talking about?
I need to find a good hub to power both my 2pacs and maybe a 3rd one.
if this is not the one..... any suggestions on a good hub to run 3 "2pacs"
Thanks in advance.
