I've been wondering why I don't experience this problem with my 
MacOS system. After looking carefully at what it saves about a 
USB connection, I discovered that it was recording the serial 
number of the FDTI interface chip. As a result, it doesn't 
matter which hub I plug the K3(upgraded to S) or the other 
USB<-->RS232 adapters I use, they are connected to the correct program.

I wonder what Linux does? If it doesn't handle reconnecting 
USB<-->RS232 well, a Linux hacker could train it to follow 
Apple's lead.
