C674x USB stack support

Do you know if TI has an implementation of a USB stack available for the DSP side of the C674x processors?

There is a BIOSUSB module available, but it is an incomplete implementation that does not support most of the USB features needed to actually use the USB interface in a real device.

It seems as though the BIOS side drivers are “lightly supported.”

Any feedback or input is greatly appreciated.
Thanks!

    There is a USB package supporting C674x DSP. The supported classes are MSC (both host and slave) and HID (both host and slave). To use the MSC, you will probably need to use ERTFS (a DSP based file system) too. Both the USB package and ERTFS binary can be downloaded and used for free.

    If you are looking for something else, i.e. isochronous USB audio class, then you are right that it is not supported.
