Maybe we should have a warning about that, > that the device should be connected to another port to get High Speed? Maybe my "attached" was misleading. The port I attached the QuickPort docking station is capable of high speed in regard of the hardware. But FreeBSD attaches the device to an OHCI instead of an EHCI. Of course I tried different ports and cables. On a different machine with the same motherboard I tested the QuickPort with FreeBSD-9.0-RC1, CentOS 6.0 and Windows 7. Under CentOS 6.0 and Windows 7 the QuickPort was set to high speed. Under FreeBSD only full speed was available. The only difference so far I could find was that wMaxPacketSize in Endpoint 0 and Endpoint 1 is set to 0x40 for FreeBSD and 0x200 for CentOS and Windows. Best regards Franz
