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. -- Add udev rules for Sony MD300 GSM modem https://bugs.launchpad.net/bugs/451787 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
