just to let you know and add that model to the list of known working devices.
A Samsung F480 works fine with smsd version 3.0.10 (no unnecessary upgrades on a production system...) OS is linux kernel 2.6.22 (SUSE out-of-the-box) x86_64.
The phone is connected with the USB cable that came with it. Setting in the phone is to use the Samsung PC suite mode.
lsusb reports the phone like this:
The phone gets assigned a ttyACMx device name automatically. For better mamageability, I created a udev rule to create a symlink with a known name for it:
(this needs to be on ONE LINE ONLY)
The configuration of this device is
'smsdconf' Syntax Highlight powered by GeSHi
The only quirks I experienced were that I had to set the storage area where incoming SMSes are stored to "SM" explicitly, and the phone uses storage slots numbered from 0.
I guess many modern phones with USB connectors would work similarly, i.e. they are acm devices and need minimal setup in smsd.conf.
Apart from that - thanks for a useful product!
