Hi!
I bought a Sharkoon QuickPort XT USB3.0 SATA docking station.
Unfortunately it is attached to an OHCI. Thus it runs at full speed (12
Mbps) only.
The docking station uses a "ASM1051 USB 3.0 to SATA Bridge" from ASMedia
(Vendor 0x174C, Product 0x55AA).
Attached to a Windows or Linux machine, the QuickPort XT runs at high
speed (480 Mbps).
Detailed output can be found here:

The problem occurs under FreeBSD 8.2-RELEASE and FreeBSD 9.0-RC1.
Does anyone have any idea how to fix it?
Best regards
Franz
