>Description:
Running FreeBSD 9.0 on an HP Microserver N40L, my external backup discs are only detected as full speed instead of high speed:
$ sudo usbconfig

Writing to the disc is only possible at <1 MB/s. The same happens with a different USB disc (tried both a USB2 and a USB3 disc with different enclosures).
The only way I could get more USB speed so far was with a USB3 PCIe card, but unfortunatly I get a kernel panic after some time during rsync transfer (I'll file a different SR for this, seems to not only happen to me [1]).
Worked fine in a linux live-CD, so it is not a hardware-problem.
If you need any additional logs, please let me know.
