I have been away from Pic's for a while to study other things. As an=20
Old, Retired Nerd my real hobby is studying.
My expectations of USB are probably unrealistic. What I think is missing=20
is a Library like I2C. All of the information is presented and the=20
client side is not limited by the host.
  There probably exists a host side driver for Windows that provides the=20
hardware connection that will permit that.
For now the USB->ttl serial chips provide the solution in my shop.
Now that I have put it in writing I see that is a pretty good solution...
