Hello

I looked at the example above and thought it might be useful for my
project. I want to use the USB as a substitue of the UART/COM.

Instead of connecting the SAM7S-USART to the PC the USB will connect to
the PC and behave like a Serial. However, the application on the SAM7 is
currently using the USART. Now, everything should be diverted to the
USB. On the side of the PC the USB should behave like a COM substitute.

WHAT I TRiED SO FAR
I looked at the example, but I don't get a clue what I have to do. I
compiled and loaded the given example application onto the EVB. I tried
to copy some inf/dll ontothe PC. But no success. The PC does not show a
COM. The EVB does not run with the program.

(1) Can you help me to get the example prog running plus PC
installation.
(2) Alter the example program that I can use it as a simple Serial

Thanks indeed

There is an inf-file for "usbser" included in the archive. When the
board is plugged in Windows should detect a new USB-Hardware, manualy
select the PC exec/inf_ser_WinARM (based on an inf-file found in
FreeRTOS.

The detection of the device and the "serial-emulation"  worked for me
the last time I have tested it. Can you give more details?

The example should demonstrate this already as far as I remember.
