DM37xx, USB OTG, Peripheral mode, Vendor ID

Hello.


I'm not sure how to approach what's bothering me the right way, here is my question in a nutshell.

How is the USB VID/PID issue resolved when applied to DM37xx development and testing? How is one supposed to tackle this problem when faced with the task of filling up the device descriptor from the bottom up? Is there some USB Vendor ID Sharing Program for DaVinci processors, as there is for MSP430 series?

Thank you very much in advance

    Hi Sergey,

    I'm not sure that understand what exactly is the USB VID/PID issue. Could you give more details about it?

    The available tools for DM37xx are listed at the product page tools&software:

    but unfortunately I don't find a program corresponding to that utility for msp430.

    Hello.

    I'm sorry for being so confusing in the original post. What I mean by "issue" is, if and how I can obtain VID for development purposes (to avoid collisions, dealing with legal sensitivity etc.). My company has never been involved in production of USB-equipped devices, which means that it does not own exclusive rights to a Vendor ID. Whether it is going to change that or not, is not clear at this point.

    Is it possible to borrow the TI's Vendor ID (which is, as I understand it, is 0x451) and apply for a unique provisional Product ID, as it was possible with MSP430?

    Thank you in advance

    Sergey,

    It is possible to borrow the TI's Vendor ID (0x451) only for development purpose. Also you can define your own values for vendor ID (VID) and product ID (PID) in the USB descriptors. You can read more technical details about USB descriptors in the DM37xx TRM section 26.4.5.3 USB.

    If you wish to use the TI's Vendor ID for commercial products you should contact with TI sales for more details.

    If you (your company) wish to have your own unique vendor ID (VID) and available set of product IDs you should read on the usb.org's site information about getting a Vendor ID at:
