CC8531: Can CC8531 configuration change device name in Windows?

Part Number: CC8531

Hi TI experts,

Customers want to change the name of the headset they connect to their PC. They developed the headset by applying the CC8531.

When connected to a PC, the device name is recognized as CC85X1.

Mic - CC85X1 USB Headset

Speaker - CC85X1 USB Headset

Is it possible to change the name recognized by the PC?

They hope to change something like this:

Mic - MIC (AZPG-W1000)

Speaker - EARPHONE (AZPG-W1000)

Please check it.

Thanks,

Downey Kim.

    Hi,

    Referring to: www.ti.com/.../swru250m.pdf

    2.5 USB
    The CC85x1 can implement a USB composite device, consisting of an audio device and a human interface
    device (HID).
    The audio device handles all aspects of the audio streaming, including volume and sample rate control, and
    the human interface device handles remote control functionality.

    2.5.1 Identification
    USB devices are identified by a vendor ID and a product ID. These values and a device release number are
    specified at configuration time. The USB vendor and product IDs may not be selected at random:
     For prototyping, Texas Instruments' vendor ID 0x0451 may be used together with product IDs in the
    range 0x16BA - 0x16C1
     For released products, a purchased vendor ID must be used
    Three USB string descriptors are implemented. These may be visible to the end-user on the USB host:
     Manufacturer name, specified at configuration time
     Product name, specified at configuration time
     Serial number, generated at run-time from the unique device ID (see section 2.2.1.1)

    The following E2E thread discusses this question and provides source code: https://e2e.ti.com/support/legacy_forums/purepath_wireless/f/purepath-wireless-read-only-forum/303363/purepath-2-1-audio-channels-system

    I hope this will help,

    Best regards,
