2. disconnect USB from PC. A message is shown on PCAN-View Trace 'Hardware plug-out'
3. reconnect USB to PC, A message ...

Can I use both PCAN USB and PCAN USB PRO (FD) in the same computer?

Either PCAN-USB or PCAN-USB PRO FD works fine on the same computer (Win 7, 64bit) but I was unable to make any one work when both drivers are installed.

I still receive all messages with odd message id (such as 0x1b7, 0x1b9) but not even id (0x1b6) in the test code below.

Please advise, thank you.
