Hi Jerome, I was about to reply about CDC device on Jaluino Cell thread, but here you are. I've experienced the exact same troubles with some recent experience with Jaluino (medium).
http://groups.google.com/group/jallib/browse_thread/thread/f8e646047db6b9b0/18b03e86fd04d58f?lnk=gst&q=+cdc+serial+linux+at+modem#18b03e86fd04d58f Basically, I tried to remove the configuration part responsible for telling host system this is modem (remove USB_V25TER). This will prevent host system from sending AT chars. The problem then is it's not recognized anymore, it actually depends on your kernel version. There's a patch in CDC kernel module, making this "empty" configuration recognized. Use >= 2.6.32 (couldn't tried though, my linux box is sick). So, FTDI or CDC ? FTDI indeed requires a driver, but doesn't CDC too ?? FTDI is also widely used, it's become a standard. I would prefer a USB converter acting as a FTDI device, but I think implementation is far from easy (and maybe not open).
