Using a custom udev rule the GSM modem is mounted instead of the storage device

i got reports from a few sides that the udev modemswitcher seems to be not working so great atm. same for bug 450237 ... though the dmesg looks different - which means it might be completely unrelated. unless martin has some idea i will probably look whats going on with our udev rules.

This device is already covered in 77-mm-ericsson-mbm.rules

ATTRS{idVendor}=="0fce", ATTRS{idProduct}=="d0cf", ENV{ID_MM_ERICSSON_MBM}="1"

Alex, do you know what evaluates this? Is that modem-manager? Is anything in modemmanager doing something similar to

  echo 3 > /sys/$env{DEVPATH}/bConfigurationValue

?

[Laudeci Oliveira (laudeci)]

The bConfigurationValue was found inspecting the result of the command $
lsusb -v -s 003:004.

Notice that bConfigurationValue is used by the WMC Device of the modem with
values 2 and 3, both works.

I dont know the meaning of then but i found info that it is related to comm
ports here http://www.mcci.com/mcci-v5/hostside/usb_drivers_wmc.html

The observation showed that bConfigurationValue=1 always mount the sdb
device, so, trying the values 2 or 3 found on lsub worked to mount it as
modem.

Sorry about my poor knowledge, I hope that it helps.

I did modify ENV{ID_MM_ERICSSON_MBM} value to "2" on file 77-mm-ericsson-mbm.rules and it seems to have the same effect.

[Sergio Zanchetta (primes2h)]

Could this issue be the same as bug #492772 (MD400)?

[Sergio Zanchetta (primes2h)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Lucid Lynx. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

Hi,

maverick's version of usb-modeswitch-data contains the switching configuration for this device. You need usb-modeswitch and usb-modeswitch-data from maverick and it should just work.

Fixed in 20100418-1 (see Debian changelog)
