</span>Ultimately what matters is the HCI controller chip that all these<br>
ports are physically attached to, regardless of how they are labeled<br>
on the PCB or in the manual. The problem with my Supermicro X11 board<br>
is that even the ports indicated as USB 2.0 (their plugs are black<br>
instead of blue as with 3.0) are physically wired to the same xHCI<br>
(USB 3.0) controller, which is the unsupported bit.<br>
<br>
You need to have an actual UCHI/EHCI controller chip in the system for<br>
illumos to be able to use it, until illumos gets xHCI support.<br>
