TUSB3410UARTPDK: TIUSB3410UARTPDK shows as unknown device

Part Number: TUSB3410UARTPDK
Other Parts Discussed in Thread: TUSB3410

Hi

     I got the TUSB3410UARTPDK kit and installed the EEPROM burner software. I was able to download a 3410_i2c communication binary file to the EEPROM. I pulled the USB plug out and put it back. In the device manager I see a device under Human Interface Device with a VID (0451) and PID (3421) . There are two questions that I would like to get clarified

1)  In the EEPROM burner,upon clicking  on  TUSB3410 EEPROM Bruner Instance (2.00) u will see the VID and PID as 451 and 3410. Whereas when I go to device manager the VID is 0451 but PID does not match this.Why?

2) In the device manager, I do not see the TUSB3410UART EVM label at all... Why?....

Please help. Thanks.

regards

Bala

    Bala,

    Are you implementing the TUSB3410 as a USB to UART bridge, or you are willing to use it as USB HID to I2C?

    We have two different implementations for the TUSB3410. One is USB to UART, which is the default implementation for which we have the firmware and driver files available at ti.com; but we also have a custom USB HID to I2C implementation, that is not documented on the device's product folder as it is a custom application but we provide the required firmware file and code examples upon request.

    From what you mention above, given the VID PID info, it looks like you are using the USB HID to I2C firmware. That firmware will enumerate the TUSB3410 as an HID device, but the current firmware has fixed descriptors data, so the VID/PID and string descriptors will not be what you entered on the TUSB3x10 EEPROM Burner application. Upcoming firmware release will change that.

    If you are trying to use the device as USB to UART bridge, you should use the appropriate firmware file. This firmware file does let you customize the VID/PID and other string descriptors accesible trough the TUSB3x10 EEPROM Burner Utility.

    Regards,
