on my Mac at work, i'm running OS 10.6.8. i would upload a screen snapshot, but this feature is apparently not working here... but here's the data which is given in System Profiler:
USB High-Speed Bus:
Host Controller Location: Built-in USB
Host Controller Driver: AppleUSBEHCI
PCI Device ID: 0x3a3c
PCI Revision ID: 0x0000
PCI Vendor ID: 0x8086
Bus Number: 0xfa
and the second one...
USB High-Speed Bus:
Host Controller Location: Built-in USB
Host Controller Driver: AppleUSBEHCI
PCI Device ID: 0x3a3a
PCI Revision ID: 0x0000
PCI Vendor ID: 0x8086
Bus Number: 0xfd
please explain to "the rest of us" how we are supposed to know whether this is a USB 2.0 or USB 3.0 from this data?

AH HA! i found another listing labeled "USB Bus", with "Hub" under it which when selected says:
Hub:
Product ID: 0x0001
Vendor ID: 0x089d (Icron Technologies Corporation)
Version: 1.25
Speed: Up to 12 Mb/sec
Location ID: 0x3d100000 / 2
Current Available (mA): 500
Current Required (mA): 0
so it looks like this 2.66 GHz Quad-Core Intel Xeon Mac only has a USB 2.0... GEEZE! looks like Apple was a bit late with its implementation of USB 2.0, seeing how the specs for it were released in April of 2000 — this Mac was released in 2006!
don't get me wrong, i love Mac's as opposed to ANY other lame PC running Windows, but i wish Apple would incorporate new technology such as this at a faster rate than it often does!
