Well I only have keyboard and wacom at any given time for USB 2.0
I do have firewire devices being used and USB 3.0 being used also at the time of transfer.
Any more ideas? I wouldnt think that pulling data from a card would stain the power supply with even a full load of devices.

The keyboard represents a unique problem for USB.
It uses almost all of the allotted power for a USB port all by itself. It only has enough power left for ONE low power mouse such as the Apple mouse. The second USB on the keyboard is ONLY for convenience of plugging in either left or right handed mouse. Any other device plugged into the keyboard can cause both the keyboard and the other device to malfunction.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Okay, well I wasn't aware of this.
So if I have my tablet and Keyboard plugged in to USB (seperately), and have a SD card reader downloading a heap of footage, I could encounter an issue? Although what you are stating may be accurate, I would imagine that make USB devices very limited, imagine editing from a USB hard drive with keyboard and tablet.. How do the pro do it? Im up for suggestions...

Things that are not being constantly plugged and unplugged can go on the back USB ports, which have a separate power allotment.
NOTHING goes on the keyboard's USB ports except an Apple mouse or equivalent.
To use more devices, add a Powered USB Hub.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Still having issues. I have nothing but the keyboard plugged in and it still drops out and I need to unplug it and plug it back in. If the keyboard is faulty, could it be possible it can disrupt or cause issues with other associated USB ports? Really need your opinon on this.

I have the sonnet usb 3.0 PCI and that has issues also. I use the sonnet (recommended) USB 3.0 card reader, and that occasionally hangs on import also. This may be something to do with power? I have Lexar 400x cards, and also trancend 400x cards.. Very strange
