AVM provides a beta firmware [1] which allows the user to but the stick into the mass storage mode again and stream the data over WLAN connection. (of course, you'll need a special AP which supports this) [1]: (german only, they haven't bothered to do a translation) http://www.avm.de/de/Service/Service-Portale/Service-Portal/Labor/7270_streaming_stick/labor_start_streaming_stick.php Of course, I haven't tested, or even seen such setup yet. But it appears to be working (based on google). Therefore, it might be a good idea to start a new user app, which does this 3-way usb-mode switching for these devices.
