Kann mir jemand erklären wie ich meinen Network Manager dazu bewegen kann die MC8775 im X61T etwas weniger umständlich zu erkennen?
OS ist Ubuntu Gnome 13.10. Das eingeschaltete Modem wird in lsusb brav als Sierra Wireless gelistet.

Derzeit starte ich zunächst Ixconn, auch da musste ich die manuelle Erkennung verwenden, und es wird eine Verbindung aufgebaut. Diese Verbindung wird jedoch sofort wieder abgebrochen. Macht aber nix, denn damit hat der Network Manager mitbekommen das da ein UMTS Modem einbaut ist. Damit kann ich dann eine stabile Verbindung herstellen.

Schalte ich das Modem jedoch mit Fn F6 ab, oder starte den Rechner neu, ist das Modem wieder aus dem Network Manager verschwunden. :confused:


EDIT Seit einigen Wochen funktioniert nun alles absolut zuverlässig. Irgendein nettes Update hat es wohl gerichtet.

hast du usb-autosuspend aktiviert? damit kommt die mc8775 nicht klar.
 
Der Usb-autosuspend war es leider nicht.
Der Fehler liegt vermutlich im Modem Manager. Der hängt sobald ich das Modem einschalte in einer Endlosschleife und gibt das Ding nicht an den Network Manage weiter.
So sieht das syslog dann aus. In einem X61 mit einer MC8755 ist der Fehler genauso vorhanden.

Was passiert denn, wenn Du den Modemnager neu startest?
Code: 
sudo killall modem-manager
 
Mit dem Befehl ist der Modem Manager aus. Richtig aus. Neu gestartet bekomme ich den dann nur noch mit einem kompletten Neustart des Rechners.
Und ohne den Modem Manager kommt der Network Manager nicht an das Modem ran.

Mittlerweile klappt aber die Übergabe des Modems an den Network Manager in ungefähr 3/4 der Versuche.
Geändert habe ich lediglich in der tlp config das sich das Modem beim Runterfahren einschaltet, und beim Hochfahren ausbleibt. Dann ist es egal ob ich es über Fn F6 oder den Schiebeschalter einschalte.

Zuverlässig ist das aber nun keineswegs.

Und dann gibt es einen fiesen neuen Fehler. Manchmal übergibt der Modem Manager die Sierra als ttyUSB0 (ttyUSB2 wäre richtig) an den Network Manager. Der Eintrag im Network Manager sieht dann prima aus, nur ist es dann unmöglich im Network Manager die Verbindung einzuschalten. Ist nur im Syslog erkennbar das da was schiefgelaufen ist.:facepalm:
 
Ich hatte es mit restart modem-manager probiert. Derzeit funktioniert aber auch der killall Befehl nicht wenn der Modem Manager seine Endlosschleife dreht.

Mal schauen wie ich da einen halbwegs aussagekräftigen Bugreport hinbekomme. Ich bin ja sonst erstaunlich zufrieden damit wie das OS mit meiner Hardware umgeht.
