I own a Tata Photon plus usb modem which is a Hauwai EC 1260 and am not able to configure it on my ubuntu installation.
I have used it perfectly on my Mandriva/openSUSE installation so there should not be any question about its not supporting linux.
the menthod I used to connect to the internet was
lsusb :- to find the vendorID and productID.
modprobe usbserial vendor=0xAAAA product=0xBBBB with AAAA and BBBB being vendor and product ID respectively.
wvdialconf : to create the /etc/wvdial.conf file followed by subsequent editing of the file to insert username and password in it.
finally wvdial ... to dial the connection. The file /etc/resolv.conf was also edited the first time to include the nameserver values
but in case of ubuntu everything fails as soon as I fire wvdialconf command. It terminates with and error stating "modem not found".
In case of Mandriva/openSUSE wvdialconf used to check ports 7 to eight ports but in ubuntu it checks only 4 ports which perhaps arr labeled S0 to S3.
Please help me to sort this thing out.
One probable error might be due to the mounting of virtual CDROM inbuilt into the device which contains the installation files for its being configured on windows.
