This means the 3G USB wireless modem has not been switched out of USB
storage mode into modem mode.
The design process works like this;
- manufacturers invent new devices with new USB product and vendor
identifiers, these can be shown in the /var/log/messages that Jerry
has asked for,
- kernel maintainers add these product and vendor identifiers to the
kernel driver for the USB device,
- a new kernel is released and installed, _or_ the user may be able to
add the product and vendor identifiers to the new_id sysfs file for
the device driver, _or_ the USB mode switch utility might be used
(depending on the age of the kernel),
- the icon changes shape, and has a Connect option instead of Remove.
For example, on a laptop here, my notes show I once had to do this:
echo '0x16d8 0x6280' > /sys/bus/usb-serial/drivers/option1/new_id
and then plug in the modem again.
So find the USB product and vendor identifiers, try using them, and
consider a kernel upgrade.
