David, Yes, the hub is powered.
Since Christoph's problem is occurring with a hardware device different from the Sheeva PLUG yet using the same OS I am thinking the problem is more with the OS.

The SheevaPlug's PSU is a bit dodgy, and I've heard persistent rumours that the USB chipset is also a bit dodgy --- certainly, my device (which has been running continuously for years) occasionally loses a USB device and has to be rebooted. Is your USB hub powered? If not, it's worth getting one and seeing if that helps. -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "There is nothing in the world so dangerous --- and I mean *nothing* │ --- as a children's story that happens to be true." --- Master Li Kao, │ _The Bridge of Birds_ -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
