Hallo,
ich habe da eine kleines Problem wo mir leider auch Google nicht wirklich weiterhilft.

Es geht um das bei meinem Laptop integrierte Bluetooth.
Auf den ersten Blick scheint alles in Ordnung zu sein und bis jetzt konnte ich auch noch keine Fehlermeldungen finden (dmesg oder syslog) aber dennoch bleibt jeder scan mit hcitool (und folglich auch mit allem anderem was darauf aufbaut) ergebnislos. An einem RFKILL kann es auch nicht liegen denn das habe ich bereits überprüft und sichergestellt das es eingeschaltet ist.

Hat einer von euch eine Idee wie ich dieses Problem lösen könnte?

Ich hatte mal ein Problem mit einem Bluetooth-Dongle, da konnte ich zwar Verbindungen herstellen, aber nur von dem Gerät aus, mit dem ich verbinden wollte. hcitool scan hat nie was gefunden … irgendwann hab ich mir dann gedacht, ich probier’s mal mit einem anderen Dongle und siehe da – alles geht. War also entweder ein Hardwaredefekt oder Linux mochte einfach das Dongle nicht mehr (lief früher problemlos – und das neue hat den selben Chipsatz).

Vielleicht ist’s bei dir auch ein komisches Hardwareproblem?

An einen Hardwaredefekt habe ich auch schon gedacht aber unter Windows 7 funktioniert das ganze einwandfrei.
Nur unter Linux bleibt der scan ergebnislos und es können auch keine Verbindungen hergestellt werden egal von welcher Seite.

Nach langen Stunden mit Google habe ich nun eine Vermutung woran es liegen könnte.
Bei einigen Vorgängermodellen meines Laptops mussten viele Linux-User wegen massiver ACPI-Fehler (vor allem im Bezug auf Bluetooth) eine neue DSDT-Tabelle verwenden. Um nun mal nachzusehen ob bei meinem Laptop auch eine Fehlerhafte DSDT-Tabelle vorhanden sein könnte habe ich meine mal mit "iasl" decompiliert und danach unverändert wieder compiliert.
Das ist dabei herausgekommen:
Code:
schmidicom@slap ~/Dokumente $ su -c 'cp /sys/firmware/acpi/tables/DSDT /home/schmidicom/Dokumente/DSDT && chown schmidicom:users /home/schmidicom/Dokumente/DSDT'

Code:
