  It's kernel 2.4.0 latest , UHCI , usb-driver in the Kernel compiliert , Microtek-driver in the Kernel compiliert.
  It's all in the Kernel.
  Which other driver du you mean ? Kernel 2.2.18 ?
  I have run ksymoops , but the computer freeze and nothing can write in file.And the computer must restart.
  So all information are lost.Or i have make a failure.
