I am using LPC1768 as CDC device connected to PXA168 which is running Linux. On LPC side, I have drivers. I have also enabled the PXA linux drivers for usb-serial and cdc-acm drive. When I bootup the board, I get following:-
Now My LPC does not detect any driver. This LPC works fine when used to connect with PC having Windows but there too If I connect to Linux PC, I dont get it running.
Can anyone help me understanding the driver for the linux and which interface will be used to access virtual serial port.

You have selected protocol '0' (zero). I had no success with this in Linux. Set the protocol field to '1' in the descriptor: The cdc_acm module will recognize the device and provide you a /dev/ttyACM* device as the serial port.
