[CQ-Contest] win-key ??

[Dale Putnam]

Happy Father's Day to you.
  I'm thinking that I could ask the experts here, so thank you, all you knowledgable folk, for sharing.
  My family got a new laptop for me, with 3 usb ports but no serial ports. I have been using a serial port keying interface, 
from N1MM to my K2, or ICOM 761, no grid block keying needed. 
  The question is, what is the easiest way to implement win-key? What/where do I find an interface from USB to K2?
 
Thank you,
