Here is the dump: http://www.tiffe.de/other/usbus1.dump

This is connecting the J-link, starting openocd twice, removing 
and reconnecting the J-link followed by a kldunload uhci.

Can't provide a dump while kldloading since usbdump stops when the driver
is unloaded.

I have no Highspeedr-Hub so this was a direct connect. Results are the same
regardless whcih interface is used.
