I have more informations: My PC has 4 built-in USB-ports, 2 in front, 2 in the rear. They work without problems with the loaded ehci-modul. if I plug in an USB-stick there he will be recognized. But: When I additionally plug in an USB-hub the hub is recognized but after a few seconds my USB-stick is logged off. A message tells me: "Unsafe disc removal..." or something similar. The same behavior I notice when there is only one usb-hub plugged in and I add a second usb-hub parallel to the first. The second hub "kills" the first. If there are any additional questions don't hesitate to contact me.
