Besides the obvious difference between a USB 2.0 vs USB 3.0 port, are there functional/tangible differences across various USB ports on a motherboard?
I'm wondering if some USB ports have functional differences over others, such as higher priority or higher bandwidth.
In Device Manager (Windows 7 x64), each of the 8 USB host controllers have differences in their bandwidth tables, particularly in the "System reserved" parameter (e.g., 20% vs 10%).
Does this mean that some USB ports will be capped vs others? I'm not sure if 1 USB host controller = 1 USB port (the eight seem to line up with the eight USB ports on the back of my motherboard).
I've read that USB shares its resources across the protocol, so I'm wondering if some ports would be better served with particular devices, like an external drive, and putting less data intensive devices on lower bandwidth ports.
