Both ports exists and are working. Also GPIB port not found ...
 
Another PC, with motherboard HSB-965P and four serial ports COM1 to COM4 (all RS232C), Windows 7 SP1, the HWinfo32 shows the same problem as above - no COM port detected.
Beside it, on the computer is dual CAN bus port and GPIB port. Also no detected by HWinfo32.
