I tried to get a USB device (pocketpc) read the USB serial, but I only partially succeeded. I can pass console=ttyUSB0 to the kernel and load the ipaq serial console driver as it oopses. I am able to echo strings to /dev/ttyUSB0 and read them on the ipaq, but I am not able to "deviate" the kernel messages to that port. Any hints on how to do that would be very appreciated, I didn't find anything usefull on the web. (I tried with setconsole /dev/ttyUSB0 but it gives error msg about device busy or something) Chris Privileged or confidential information may be contained in this message.
