Ok. I made one more test: disabling all usb in the bios.
(Sorry, can not unplug. It's onboard.)
Booting to init 1 without loading the usb-drivers.
Same results. 37MB/s initial, 55MB/s after loading the
burnK7 programm in background. Unloading bunrK7 and
transfer-rate is back to 37.
So this time no USB-device is connected and no driver
loaded. USB-ports disabled selected in the bios.

If you still think this is a usb-thingy I will shift
my communication to linux-usb-devel.

Helmut
