The modem is composed by
- A modem. (Why not?)
- An USB mass storage, read-only, containing Windows drivers
After I got the USB Huawei E1552, I wanted to to try it out on a spare Laptop running Microsoft Windows 7 32bits. I failed, because the driver provided on the USB stick is XP/Vista only, and known to be weird on Microsoft Windows 7 32bits.
If the usb-modeswitch package is not installed, when plugging the modem, only the USB mass storage part is detected:
usb 1-2: new high speed USB device using ehci_hcd and address 3 Initializing USB Mass Storage driver... scsi6 : usb-storage 1-2:1.0 scsi7 : usb-storage 1-2:1.1 usbcore: registered new interface driver usb-storage USB Mass Storage support registered.
After installing usb-modeswitch and without any setup, when plugging the modem, the the USB mass storage part is detected and actived, then switched to the "GSM Modem" feature:

I use wvdial to connect to internet. This is the wvdial.conf part:
[Dialer orange] Init0 = ATZ Modem Type = Analog Modem Baud = 921600 New PPPD = yes Modem = /dev/ttyUSB0 Phone = *99# Username = '' Password = '' Stupid Mode = 1 ISDN = 0Thanks to Elie Zedeck Randriamiandriray for the tips.
To connect, just run wvdial orange and you're done.
Using Gnome Network Manager
