Detecting when the user is inserting a USB token

Question

Dear Forum,
From a Java GUI application I'm trying to detect when a USB token (CrypToken from Marx) is inserted.
When I run the program below with the USB token inserted it works fine. If I start the program and then inserts the USB token I keep getting a ProviderException.
Any help is greatly appreciated.
Kind regards,
Morten Bruun
The exception I get:

Thanks for replying, Andy!
I know that if I point my gateway at 2013, I should be fine.  You mentioned that in this article: 
http://social.technet.microsoft.com/Forums/sharepoint/en-US/f622ff81-0d97-44d3-9051-f22c381fe188/exchange-2010-and-um-on-exchange-2013?forum=exchangesvrunifiedmessaging
"Once the SIP connection is pointed to 2013, it will handle both the 2013 and 2010 Mailboxes in the Dial Plan" which I found and which was helpful.
But, in the TechNet walkthrough:
http://technet.microsoft.com/en-us/library/dn169226(v=exchg.150).aspx 
And the checklist too:
http://technet.microsoft.com/en-us/library/dn169228(v=exchg.150).aspx
It's having us move the UM enabled users before we repoint the IP gateway, which is one of the final steps. Since we're just in pilot mode right now, we'd prefer to not re-point that just yet.  Do you expect it shouldn't work?  Is TechNet wrong or
am I misreading it or missing something else?
