I inserted two Bluetooth 3.0+HS Dongles in the PC and created USB-filters in the virtual machine for these: as one bluetooth3.0+HS dongle has two chips inside (one for bluetooth-, one for 802.11g-standard) I created a filter for Bluetooth and for 802.11g adapter for each of my two Ubuntu systems. After starting both Ubuntu systems parallel, each of them successfully recognized the Bluetooth-adapter. Also the 802.11g-adapter was recognized ("ifconfig" displayed a "wlan"-adapter). So I tried to send some big data files over bluetooth between these two virtual Ubuntu systems: This worked well, but only with Bluetooth-speed (~2MBit/s) ! As I understood, Bluetooth3.0+HS should use the integrated 802.11g-adapter to send bigger data files with ~24 MBit/s. What could I've done wrong? Why does bluetooth not use the "Highspeed"-modus? Regards, Steffen PS: I tried it with a 10 MB, 20 MB and 50 MB file (.mp3, .wav & .avi) -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com" target="_blank">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> It's very good English!
