Testing

Clearly explain the issue in detail, with snippets of schematic (or ref to the exact page), layout, etc, as needed

There is a USB interface connected between GBC and BB. BB will act as USB host and GBC will act as a device using CDC ACM class driver. The Linux kernel in the BB and GBC has to be configured for USB support and tested as a part of DVT.

As discussed GBC SDK does not appear to support peripheral mode though the HW controller itself support it. We have enabled all available kernel peripheral drivers but GBC does not appear as device on the host. To further continue in the test, peripheral driver is needed from Cavium. Please suggest.
