I have a guru server plus which need to work with a huawei e1550 gsm modem.
The modem was recognized as usb storage. I do a search found that it need to have a modem switch mode udev software.

I try the suggestion to install udev-extras, it will install the usb_modeswitch software which will switch the modem from storage mode to modem mode:

apt-get install udev-extras

but looks like this package is not there. anyone know where I can get the package, or I will try to build the software from source.

OK, I finally get it working by compile the usb-modeswitch

Here is how I get it work, maybe some one can create a package in the repository:

1. download usb-modeswitch and usb-modeswitch-data:
    http://www.draisberghof.de/usb_modeswitch/index.html#download

2. install libusb-dev in guru plug, it will auto install the dependency which include the gcc compiler.

3. install make and tcl.

4. compile the usb-modeswitch-1.1.5, do a make install for usb-modeswitch-1.1.5 and usb-modeswitch-data, this should create the binary and rule in /lib/udev

5. add one more entry for E1550 in /lib/udev/rules.d/40-usb_modeswitch.rules, I copy the line for E1553, change the product id to 1446 for E1550.

6. plug in the modem, it detect as storage, then it auto disconnect and detect again as usb modem
