I need help with this problem:

My PC cannot receive serial data sent through a PIC18LF2450 RS-232 to USB =
=20
interface.

I have a PICDEM PIC18 Explorer Demonstration Board.

I am trying to have it send serial data from the PIC18F8722 using the =20
PIC18LF2450 to use USB
for sending data to my PC.

The firmware on the  PIC18F8722 works fine when I use the RS-232 interface =
=20
to the PC.
But when I use the USB serial interace, PIC18LF2450, the data transmitted
 from the PIC18F8722 do not make it to the PC.  Data sent by the PC to the =
=20
PIC18F8722 gets
to the PIC18F8722 just fine.

The PIC18LF2450 seems to be working enough to show up as a serial port =20
COM3 on
Windows Device Manager, when it is connected to a USB port on my PC.

But something is wrong, and I can only send data from the PC to the =20
PIC18F8722 using the
USB interface, and the PC cannot receive data from the PIC18F8722 using =20
the USB interface.

My PC is running Windows 2000, Service Pack 4.

Thank you,
