Hi, I'm using a 8051 MCU which comes with a USB dongle. My question is "How can I configure the USB to be read as a COM port?" Has anyone done it before? All I know is that I need to configure the USB as a Communication Class Device but how do I go about doing it? Any help is very much appreciated.
"So I'm trying here to see if anyone here has done it before."
Why don't you code it by yourself? I don't have any experience on this chip. But at a glance, it is an usual USB engine. Nordic should have some USB example. Based on this example, you can port the implementations of CDC on other USB MCUs.
You'll find many CDC implementations I posted one of them to SiLabs forum. USB CDC implementation for 'F32x www.cygnal.org/.../000945.html USB CDC implementation query www.cygnal.org/.../001336.html
USB spec defines the behavior of USB engine (SIE) on the device in details. Then, the firmware code is much the same for '51, ARM, H8 or PIC, etc.
If you are not familiar with USB implementation, it's a good opportunity to start it. I'll help you.
BUT IN OTHER FORUM!!, which doesn't discard my post! Post it to 8052.com

I am trying to code it myself, but I'm not too familiar with it so just need a bit of help to get going.
Ok will post to 8052.com Thanks for the help!
have not been there for a while, but http://www.usb.org/ has a forum that AFAIRC will be much more helpful than this re what you need.

Thanks for the suggestion I am waiting for the administrator to approve my account on http://www.usb.org
