That's really quite odd. The following should be similar to what you did and it *does* seem to work just fine, for me.
I find the problem.
It's into usbtty_poll() which calls write_buffer() when the USB device get connected (usbtty_configured() is true).
Function write_buffer() calls udc_endpoint_write() who calls driver low level function. This low level function, PXA270 specific, waits all data has been transmitted before returning to the caller, this because I need to know when a packet has been transmetted before sending a new one or I get some data lost during transmission.
When I connect kermit/minicom to /dev/USB0 the UDC sends stdout data and everything works well...
How I can resolve the problem? Maybe using a timeout during transmission?
Thanks,
