I understand what is happening, but the big problem is that if I'm using multiple devices I need to uninstall or disable them all to use only one hardware input from USB, if what I need to do is coming from hardware... but I'd like to know how other people in this forum has achieved to use TouchOSC with its bridge which is a virtual port, I hope with a software trick, because I'm afraid that even in this case the only solution was to have only this port on the entire system...
