Where can I find a driver that will enumerate the USB slave port on the Mini2440 as a UART? I would like to connect the Mini2440 to a host computer that runs a application with UART communications. The host computer does not have a serial port.
A current linux kernel comes with all drivers you need to make the Mini2440 acting as a serial or printer device when connecting to a host.
Hi Juergen, Do you have any pointers on how I can accomplish that? Where will I get the drivers for the host side? Libusb? Thank you
If the host is also a Linux based system you only have to load the USB drivers for serial or printer devices (it depends on the module you load at your Mini2440). At the end you get a device node in dev/ on your Mini2440 and your host you can open/read/write on both sides
If you're talking about the USB Device as a Serial connection, You can use one of the usb gadget kernel modules (the serial one). Documentation/usb/gadget_serial.txt Zogzog.
Hi Zogzog, The gadget serial drivers works great thank you. MC
