[Bug 522998] Re: XHCI (USB 3.0) kernel Module Prevents Suspend

[d3mia7]

Agreed, this is probably not fixable in terms of total functionality
under Lucid (and possibly not even under Maverick), however there needs
to be some sort of workaround in place especially as this is an LTS
release.  Within 6 months USB 3.0 ports will start to become standard
across the board.

In my humble opinion, blacklisting XHCI is a totally workable solution
given that the ports will continue to operate as USB 2.0 ports.  There
are precious few USB 3.0 devices available yet, and those devices will
work fine as USB 2.0 devices if that's all the system is supporting.
The most important questions in my mind would be:

- Will the system suspend/resume?
- Do the USB ports work when devices are plugged in to them?

Those two issues are far more important than "Do the ports work at full
USB 3.0 speeds even though there are no current devices that can make
use of that capacity?"
