Is there an Embedded Linux USB-Serial device driver in the kernel?
Added by Mike Costa over 12 years ago
I have a L138F with profibus board and am looking into options for communicating with a PC. I'd like to use USB if possible. Is there a device driver in the linux kernel that will allow the OMAP to enumerate as a USB-Serial device on a Windows machine?
Thanks,
Mike

If you have the USB1.1 port hooked up (it is on the Industrial I/O profibus card, it's the a USB-A host connector), you can use pretty much any off the shelf USB to serial converter such as a Keyspan. If you have the drivers configured in the kernel configuration, the udev scripts should create a /dev/ttyUSB0 device when you plug it in.
I haven't personally tried the Serial Gadget devices on the USB0 (the 2.0 OTG port), but we have had customers use the RNDIS mode to create a USB-network style connection.

If you are interested in making the USB 2.0 port look like a virtual serial port, here is more information about the Serial Gadget device (you'll need to reconfigure your kernel to get this going).

The Serial Gadget device is exactly what I am trying to do. thanks for the link, I will post how this goes.
