In an earlier version of this document the USB interface was documented with three additional
components. These three components need to be removed in order to allow detection of discon-
nection and reconnection of the USB connection and reestablishment the USB connection in case
the COMX module was reset by the operating system Windows.
Don’t use the three components as shown in the following figure for the COMX modules revisions
