Can't help you with the Icom, but I am running Kenwood software for both 
the 480 and 2000 on Windows 7 64 bit with no problems.    Am also 
running a 4 port serial to USB box.  Have connected both radios, a FSK 
keying adapter and a CW keying adapter.   Everything works fine with 
these exceptions:  First time I ran high power, the logging software 
froze up and I had to reboot.  A few ferrites on the input and output 
cables of the usb/serial box solved the problem, and almost 2,000 high 
power QSO's  with no other problems.

The other slight problem is more a Win 7 problem.   USB to serial CW 
keying works, but can be finickey.   Just ask Lou, WA3MIX from this list 
who was working me on CW  a week ago.  My pc put my cw into warp speed 
and went berserk.  I had an e-mail program open at the same time.   I've 
heard that  this problem can occur when the computer is  trying to do 
several things at once, and CW timing can suffer.  I now make sure all 
other programs are closed and have had no other problems with CW.
