MSP430F5659: Digital Signed USB CDC driver name change as per our product name

Nitesh Padiyar77

Part Number: MSP430F5659

Hi,

I am using MSP430F5659 controller with inbuilt USB. USB uses CDC protocol for the communicate with PC based application.

We use the Digital signed driver for our UI application, We see our device is listed as MSP430 serial device in device manager.

Can we change the name from "MSP430 serial Device" to our own device name?

If so how to make that, Its very urgent and we are in urge of our device release to market this month end.

Any one who has done the name change on the digital signed driver please help me.

Thanks in advance

    Hi Nitesh,

    yes, it is possible to change the device name, but you _must_ sign the changed driver (I suppose we are talking about "Windows [TM]") .
    You should consider to change the USB VID/PID, otherwise this might create confusion on customer side.

    However, Microsoft has a good description on how to sign a Windows driver: Driver Signing

    Hello Nitesh,

    The reason you see the MSP430 specific one is due to the Vendor and Product Ids associated with the USB peripheral and SW. I'm not completely sure about the driver signing process, but I believe it would be tied to the VID/PID associated with the USB. If you wanted to have a custom one that featured your company/product, you would need to apply for a Vender ID with the USB organisation.

    Hi,

    So is it possible to change the driver name in .cat file and .inf as per our product name, without registration? Can TI support on this?

    Since we are close to our release and registration may take time. So we need help from TI. Or faster ways to get the VID/PID ?

    Thanks in advance

    Any CDC device (msp430 based or not) will be enumerated on Win 10 automatically (without questions) and will use native OS drivers.

    Hello Nitesh,

    After speaking with our USB expert, you can change the .inf but then the .cat and .inf will not match and that may cause installation issues. We are unsure fo that.

    TI does have a process for you to get a specific PID, but the VID will still by TI MSP430. ( software-dl-1.ti.com/.../vidtracker.html )
    I'm not sure if this will help with the display name change however, as i'm unsure if windows does this exclusively through the VID or via VID+PID.
