Hi Greg, After a new complete reading of my code against usb-serial.c, I finally found ( I hope ) my problem. In usb-serial.c, when bulk_in/out buffers are initialized, each buffer size are the same as the wMaxPacketSize given by the endpoint. So, in my case, my device have a value of 64 bytes and I send and receive bulk data that might have 256 bytes length !!! And like pl2303, I just copy the user data to port->write_urb->transfer_buffer. For all driver that use usb-serial for the probe function, this can be a problem (like for me). I have checked for example the pl2303 that never check this value before the memcpy.
Am I right ? This can be problem or not ? Alain ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
