Hi,
We are about to wrap the initial set of USB 3.x support. If you have
some additional cycles to perform some testing of this (regardless of
if
your system has USB 3 or not), we'd appreciate it.
If you do test it, and things are working, it'd help me if you could
share the output of the following two commands for my notes:
mdb -ke '::prtusb'
prtconf -dD | grep -i xhci
This on an HP MicroServer Gen8 (Intel Xeon E3-1220L v2)
a) with the boot USB plugged into a USB-2 port:

As a footnote, according to the documentation the two USB 3.0 ports on
the HP Gen8 are not functional at boot time.
I've just tested this and indeed the system doesn't see a boot device
plugged into one of the USB 3.0 ports. :-(
Here's the User Guide text:
USB support
HP provides standard USB 2.0 support, standard USB 3.0 support, and
legacy USB support. Standard support is provided by the OS through the
appropriate USB device drivers.
Before the OS loads, HP provides support for USB 2.0 devices through
legacy USB support, which is enabled by default in the system ROM. USB
3.0 ports are not functional before the OS loads. The native OS provides
USB 3.0 support through appropriate xHCI drivers.
Legacy USB support provides USB functionality in environments where USB
support is not available normally. Specifically, HP provides legacy USB
functionality for the following:
• POST
• RBSU
• Diagnostics
• DOS
• Operating environments which do not provide native USB support
