USB3 Ports not always recognized correctly

Sat Jan 26 16:11:03 UTC 2013

I've got a mainboard with two USB3 ports (and a whole bunch
of USB2 ports).  But only the first USB3 port is recognized
correctly.  When I connect a USB3 device to that port, it
works.  It also works (albeit slower, of course) when using
one of the USB2 ports.  But when I connect the same device
to the second USB3 port, it fails.

The board is an "ASUS M4A88TD-V EVO/USB3", and I'm using
FreeBSD stable/9 that's just a few days old (2013-01-22),
including r245734.

This is how the controllers and ports are probed:

For testing I'm using an external HDD ("HGST/Hitachi Touro
Desk DX3 4TB").  On the first USB3 port it works fine with
80 MB/s sequential speed.  It probes like this:

15:54:24 ugen0.2: <HitachiGST> at usbus0

When connecting the same disk to the second USB3 ports,
it fails in this way:

Of course, no device appears.  I notice that it attaches to
usbus2 that is only probed as "480Mbps High Speed USB v2.0"
according to the boot messages above, even though this is
a USB3 port.

Just for comparison, when I connect the same disk to a "real"
USB2 port, it is detected correctly with the following output:

15:20:47 ugen4.2: <HitachiGST> at usbus4
15:20:47 umass0: <MSC Bulk-Only Transport> on usbus4
15:20:47 umass0:  SCSI over Bulk-Only; quirks = 0x4101

By the way:  This disk uses 4096 bytes per sector, so you
cannot use fdisk, and my mainboard would probably be unable
to boot from this disk (which is not a problem for me,
because I don't intend to use this particular disk as a
boot device).
