HELP! mac mini doesn't recognize all the usb miners using anker 9+1 hub

[zpply]

Wow. I've posted on a few different locations around here trying to get this going with no luck. I've got a mac mini with anker usb hubs 3.0 9 + 1. I can't get all the eruptors to all show up on the hub. I've tried different combinations, I've tried connecting the hubs first then plugin each erupt ors one by one - first hub fills up ok. second hub gets to 6 then won't recognize 7,8,9 and 3rd hub doesn't recognize anything.

I've tried having the eruptors already connected then plugin the hubs into the mac mini by usb and it randomly lights up a few eruptors on each hub - really weird. Doesn't seem to recognize more then 15/16 - I have a total of 25

Mac mini is new running 10.8.4

I've installed these drivers for the USB miners - http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

Not sure what else to do? Only thing I can think of is installing Windows 7 via bootcamp and trying to see if windows will recognize all the hubs and eruptors.

Is it the mac mini is it os x - what the hell!

can i run the usb eruptor direct from computer usb?
would x6400 interfere with usb block eruptor

in addition i also problem setting up on cgminer.
using 3.1.1 or 3.2

or can i run all via mpbm?

running on windows 7 x32

It actually looks like a limitation in OSX and the type of drivers that are used.  A quick Google shows that there are others having USB issues with all items in general once they get past 8 or 9.  Doesnt look like OSX supports that many devices connected at once.

from all my testing it does appear to be something with OSX. I'm working on running Windows 7 and Windows XP by VMWare and see if I can get this resolved.

Each eruptor in the hub requires 0.5 amps.  If you have a 2.0 amp psu you can only run 4 eruptors, anything more and you start to have problems.

I had terrible luck with WinXP.  But Win7 was very easy to get working.

Does VMWare allow VM's direct access to the USB ports?
