We have got a PCB with 2 FTDI 4232 IC's, which gives use 8 VCP comm ports. Our problem is that we don't "see" all 8 comm ports using VB6 or RealTerm or TeraTerm. The number of ports we can see differs each time we unplug and replug the usb connectors. Under Windows's System->Hardware-> Device Manager->Ports we do see all 8 comm ports, every time.
What is going on here/what are we missing?
