 Hi HPS,
 
 can you provide me with some more details?
 I'm not so familiar with this usb stuff.
 
 I got it working with the command you mentioned above. But it is limited
 to the specific usb port, isn't it?
 
 You also mentioned a quirk table. Can you provide me with a small howto
 or a website showing how to add an entry to the quirk table? I haven't
 found anything in Google.
 
 If I've added my device to this table. Do I have to redo those steps
 after upgrading my system to a newer FreeBSD version? I'm building the
 new world and kernel from the sources.
 
 Hope my questions don't annoy you, but I've no clue where to find the
 information I need.
 
 Regards,
 
 Chris
