Public bug reported:
I think this it not a bug itself. When the Sony Ericsson MD300 is
inserted, its not recognized as a 3g modem, just as a block devide. To
make it to work i need to create the file
/etc/udev/rules.d/50-md300modem.rules with the contents:
ACTION!="add", GOTO="3G_End"
BUS=="usb", SYSFS{idProduct}=="d0cf", SYSFS{idVendor}=="0fce",
PROGRAM="/bin/sh -c 'echo 3 > /sys/%p/device/bConfigurationValue'"
LABEL="3G_End"
Then, i just need to restart udev and the modem are correctly recognized.
(i take this trick from the site http://laudecioliveira.org/blog/?p=70).
I don't know if i need to open a new bug, but the network manager only
activate this modem in the 'auto' mode, where it choice the band (2G or
3G) automatically, and i can't set it to work only with 3G (i can do
this sending the command AT+CFUN=6 to the modem, but NM cannot permit to
the user change the modem init strings.
System: i only tested this with ubuntu 9.04 and 8.10 (i386 and amd64).
