Public bug reported:
Binary package hint: udev
Hi,
newly installed Ubuntu maverick 10.10 (development branch - alpha 3) and found
a little nuisance that IMHO might have something to do with udev (version
151-12).
When huawei e160g usb key is inserted a device for the USB Mass Storage driver
is regularly created (e.g. in /dev/sr2) but no device for the modem part is
created (e.g. /dev/ttyUSB{0,1}). On the other hand, everything worked well in
Ubuntu 10.04.
In fact after inserting the key, in dmesg there's no trace of ttyUSB or similar:

Some more infoz...
:~$ lsusb | grep -i modem
Bus 001 Device 004: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem
/ E270 HSDPA/HSUPA Modem
:~$ lsmod | grep -i usb
usb_storage 50372 1
usbhid 42062 0 # mouse usb, etc...
hid 84614 1 usbhid
so if one does:
$ sudo modprobe -v usbserial vendor=0x12d1 product=0x1003
insmod /lib/modules/2.6.35-14-generic/kernel/drivers/usb/serial/usbserial.ko
vendor=0x12d1 product=0x1003
the key works again as expected; from dmesg:
[ 6991.003646] usbcore: registered new interface driver usbserial
[ 6991.003688] USB Serial support registered for generic
[ 6991.004591] usbserial_generic 1-6:1.0: generic converter detected
[ 6991.011558] usb 1-6: generic converter now attached to ttyUSB0
[ 6991.011591] usbserial_generic 1-6:1.1: generic converter detected

[ 6991.014576] usbcore: registered new interface driver usbserial_generic
[ 6991.014582] usbserial: USB Serial Driver core
/dev/ttyUSB* are automatically created and the modem is ready for
networkmanager.
Sorry for poor English; hope that helps.
