Hi,

We are using TMS320C6746 high speed DSP core processor based customized board for one of Our Project. We are using inbuilt USB core of TMS320C6746 as USB peripheral/device in our project for USB based application .

Hi Rajkumar,

For TMS320C6746, you can use the starterware examples of C6748. You can download it from http://www.ti.com/tool/starterware-c6dsp

The starterware has the USB device serial example which uses the CDC driver. You can take that as a reference to find anything missing in your code.

In addition, if you are looking for more information like CDC device enumeration and writing CDC Device application, please refer to TI Starterware USB wiki page under section CDC class.http://processors.wiki.ti.com/index.php/StarterWare_USB#CDC_Device_Class

Regards,

Shankari.
