I've read, that that my modem must be switched from mass storage mode to modem mode.
I have new Raspbian (downloaded 1 week ago), it has kernel 3.12.22+.
I have usb_modeswitch installed today from Raspbian repository (current version?).
When I run usb_modeswitch manually:
root@raspberrypi:/home/pi# usb_modeswitch -v 19d2 -p 0154 -V 19d2 -P 0117 -M "5553424312345678000000000000061b000000020000000000000000000000"
(these parameters can be found on many many sites by googling "modeswitch 19d2:0154")
it returns:

-> Run lsusb to note any changes. Bye.
When I run lsusb - device remains unchanged, it's still 19d2:0154. In /dev directory there is no /dev/ttyUSB0 device.
My modem USB power pin is connected directly to 5V/2A power supply.
When I was installing this modem it 1 year ago on old Raspbian everything just worked. Now im reading one USB modem tutorial after another and... it doesn't work.
New kernel is not supporting that modem or something like that?
