Bc2000 (for the BCF2000 & BCR2000)

I'm using my BCR2000 with the new MIDI Behringer MIDI drivers, however I'm noticing an annoying issue.

If you experience this issue, I'd like to here confirmation.  If you don't ever experience this issue, I'd also like to here from you so that I know that it's an issue with my system alone.

The problem.  Typically the ports for my BCR2000 are named as follows:

BCR2000 port 1
BCR2000 port 2
BCR2000 port 3

However, every once in a while they show up as

BCR2000' port 1
BCR2000' port 2
BCR2000' port 3

- or -

BCR2000? port 1
BCR2000? port 2
BCR2000? port 3

Please, if you do or don't experience this issue, I'd like to hear from you.
