JMS539 SuperSpeed -> SATA II bridge, Q77 chipset XHCI on 9-Stable

[Daniel Mayfield]

I have a new Q77 chipset Core i5 machine with a J-Micron JMS539 based 4 disk JBOD (Sans Digital TRU+4B) attached to the USB3 ports on the machine. The device only shows up as HiSpeed (USB2.0) rather than SuperSpeed (USB3.0). I've updated the firmware on the JBOD and there is no more current firmware on the Q77 board (ASRock Q77M vPro). If I disable the USB2 controllers, I can't even get FreeBSD to see the JBOD attaching. Any ideas?

Hi,

You might want to look at the Linux XHCI driver. They have some quirks to
switch ports to USB 3.0 which we don't have in FreeBSD yet. This is typically
done to not break legacy support with older OS'es.

Also check settings in the BIOS.
