Hello

I have a stupid question.

I import example project from USBVideoclass sample from sdk.

import->general->existing project into workingspace and select copy project to the workingspace.

I just want to change the prodcut name to try first.

I modiyf "FX3 "to "AAA" then i use control center to burn into ram.

After doing that, I stll see the name "FX3" from windows device manager.

Could anyone give me a suggestion?

const uint8_t CyFxUSBProductDscr[] __attribute__ ((aligned (32))) =

{

    0x08,                           /* Descriptor Size */

    CY_U3P_USB_STRING_DESCR,        /* Device descriptor type */

    'F',0x00,

    'X',0x00,

    '3',0x00

};

It should work. Try to check if you have made any mistake.

1. Download the default firmware and FX3 will enumerate with the name "FX3"

2. Modify the firmware and download it.

3. After enuermation, the device name is still "FX3" instead of "AAA". Right click and choose "uninstall".

4. Scan for hardware changes. Then host will find a new device connected and try to install driver for it. After that, the new device name will appear.

Hello,

Please ensure that the firmware is built successfully from Eclipse IDE by checking the timestamp of the IMG file.

Best regards,
