I changed my mobile card due to a change of my notebook where the new one no longer supports pcmcia cards. So I switched to the Huawei E220 usb UMTS Modem. The drawback, it does not work from scratch, the benefit, the signal strength is much better.
So the device is recogniced as an scsi storage device if you plug it in.
You have to close all open windows showing content of the device and unmount the device.
call the follwing commands:
to unload the storage device, then call:
and write down the vencor id and produc number of the attached device, then call
modprobe usb-serial vendor=<vendor id> product=<product id>
unplug the device, replug again and check that there are three usb devices calling:
ls -la /dev/ttyU*
if there are 3 devices you can use the device with kppp or wvdial. The modem device is ttyUSB0
ATTENTION: don’t forget to execute all commands with sudo
