#12 no listDevices****() method work if...

[Anonymous]

The scenario is:

I have two similar FTDI chips connected to the same laptop. I open a connection through a terminal Client to one of them and by the other hand I launch my program which make a listDevices() call, when that happen, listDevices throws:

25-jun-2010 17:30:26 com.ftdichip.ftd2xx.Device open

I assume that it shouldn't happen since im not trying to open it, just to list available FTDIs. I dont want to close the Com of the other FTDI if I want to open a connection through ftd2xxj to the other... Any idea?
