It works in Windows and automatically downloads the driver…

Any ideas how to connect to it?

Is this on a particular device you need to talk to or are you using this IC in your designs?

I for one only use FTDI parts as I have had no issues ever in using these to add USB to all of my embedded designs.


#4

What driver does it download under Windows? Can you screen capture the driver details from Device Manager for all the property pages.


#5

Looks like a simple RS232-USB converter, like the aforementioned FTDI part.

The .exe link on that page I posted is the driver.
