No, don't modify the usb serial core for this. If you really want a bigger buffer, then just create your own buffer in the driver and use that. Just like the anydata.c driver does it. Why not just add your device id to that driver instead? thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
