Hi guys, I tried to look into this a few months ago, but eventually gave up due to bugs in libgpod (see below).

(this would be more tricky, but could use udev env USBMUX_SUPPORTED) I spoke to the media-player-info guys (mainly to propose patches to improve the ipod rules they ship), and they told me that m-p-i is mainly meant for supporting regular mtp devices, and that imobiledevices are out of scope for it. They pointed me to libgpod instead. It looks like libgpod should indeed give us a very nice way to identify the device. It will export the relevant information (device, custom name of device, icon, etc) as udev attributes. It turns out that this does not work correctly with the device I have (iPhone 3) and it was not obvious to me what the problem was, so I stopped here. I think the correct solution would be to fix libgpod, and use the information exported (which should be much more accurate and detailed than what m-p-i contains) through libudev. Looking forward to imobiledevice support in Amarok ;-) Cheers, Tom _______________________________________________ Amarok-devel mailing list Amarok-devel@kde.org https://mail.kde.org/mailman/listinfo/amarok-devel
