Hallo zusammen,

ich verwende DD-WRT v24-sp2 (12/24/10) big (SVN revision 15962) an meinem Netgear WNR3500v2/U/L.

Wenn ich den 3G Stick direkt am USB-Port des Routers anschliesse, funktioniert die Verbindung wunderbar.

Verwende ich einen USB-Hub, funktioniert der Stick nicht. Das automatische 'usb_modeswitch' wird nicht ausgeführt.
Nach manuellem Ausführen von usb_modeswitch
Code:
usb_modeswitch -v 0x19d2 -p 0x2000 -V 0x19d2 -P 0x0063 -m 0x01 -M 5553424308E0CC852400000080000C85000000240000000000000000000000

werden die Treiber geladen und der Stick wird erkannt. Die Verbindung wird aber nicht aufgebaut. Nach etwas probieren habe ich herausgefunden, dass das Modem nun auf /dev/usb/tts/1 anstelle von /dev/usb/tts/0 reagiert. Gibt es eine Möglichkeit den Device-Pfad zu ändern?

Vielen Dank im Voraus!

nvram show | grep 3gdata

nvram set 3gdata="/dev/usb/tts/1"

nvram commit

but you may have to kill the pppd connection watchdog because it will reset the 3gdata variable.

do ps and look for the process id of a ppp process with redial 30 as argument.

Your modeswitch message does not look like anything seen before for this stick, it has changed the interfaces order and may also have changed modem mode.
Good luck ! Very Happy

Thanks for your help.

The ppp process seems to be rescheduled after killing, the nvram variable is always resetted to old value.

Edit: The path /dev/usb/tts/3 seems to be correct. This is used while the stick is directly plugged into the router. But if connected via usb hub, the conection can't be established. The nvram variable 3gdata is always overridden to /dev/usb/tts/0. Any ideas?
