TUSB3410 being seen as Mass Storage device

Steve Thomson
Prodigy 10 points

I have an embedded system design where I need a TUSB3410 (or similar) device to provide communication between a Host PC and my embedded micro which does not have USB but only has a UART interface.  Therefore I'm looking at using the TUSB3410.  However, when connected I need the Host to see this device as a Mass Storage endpoint and not as a Serial endpoint.  In other words, I need the Host to be able to communicate to the embedded system via a network interface over USB rather than via a COM port interface over USB.  Is this possible with the 3410 or if not, is it possible with some other USB to Serial device from TI?

Thanks.

    Steve,

    While the TUSB3410 was designed for the COM port replacement application - or VCP as we call our software package, the actual device is a programmable solution.  Therefore, it should be possible to develop firmware that utilizes the Mass Storage Class driver - or any other class driver for that matter - assuming the code space is under the RAM code space of the TUSB3410 which is 16KB.  We have not done so, but other customers have developed their own firmaware for a variety of applications.  Since you want to talk to a UART on your micro, the TUSB3410 would be the best option from TI.

    The VCP source code can be made available if you would find that valuable by sending a request to usb@ti.com.
