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.
