Hi friends,
I have the AT91SAM7SE-EK kit.

I am working in the KEIL uvision3 (Real view) tool.
Right now i am working in the USB-CDC programming for the AT91SAM7SE512 processor.

I have a example source code for AT91SAM7S64 processor in IAR workbench tool.
Downloaded from http://www.siwawi.arubi.uni-kl.de/avr_p ... _at91.html .This IAR code is working very well.

So, I have coverted the code from IAR to keil tool for AT91SAM7SE512 processor.

The Problem is

1. when i connect the device to the host ( PC ), I am getting the message "USB device is not recognized".

2. can I include any files to this?

If you need i will post my code.


Could you please advice me on this.


With Regards & Thanks,
