There is no “USB” item in the Set PG/PC Interface – Local Connection – Connection to, only serial port RS-232 (COM3) connection is there.
I experienced the same problem before, when the drivers of PC adapter USB where installed _after_ Step7. Consequently the problem was solved by changing the sequence: first the drivers of PC adapter USB, then Step7. Now any sequence doesn’t help, also keeping the PC adapter on or off during/after the installation. Also tried to check without Step7 installed (used to work like that before).
Now the same installation distributives are used (all latest versions), only a different laptop – without COM port.

Please help.
