I've been using a USB3 external backup drive with no problems
since fedora 16 (which is around the time I got a new system
that had USB3 ports in it).

Thanks for the info Tom.

I will be installing F17 on a friends Computer that has USB-3 ports on
it and I wanted to be sure.


I would imagine that those 3.0 ports are backward compatible with USB-2
devices.

Yep, but you won't notice any speed improvement without a
USB3 driver to plug into it (and they are a lot faster).

You can plug any USB 1.1 or USB 2 device into a USB 3 port and it'll
work...but at whatever speed the device is capable of.

USB 3 devices will work at USB 2 speeds. You won't get USB 3 speeds
without a USB 3 driver for the port and I don't think any of the
current drivers are USB 3. I could be wrong there.

Since there are many USB3 chipset manufacturer, why don't you download
a live disc of Fedora and run that with an external USB3 storage
device before install. If you have USB3 connectivity, you should get
around 60-80 MBs. USB2 gets about ~20-30 MBs.

The Fedora 17 kernel is new enough to do USB 3.0 (XHCI) properly.

Yes - although you find the odd device that at the hardware level refuses
to play. Pretty much all boards have a mix of USB-3 and USB-2 only ports
for this reason and for pricing reasons.
