I had correctly configured Tata Photon Plus on Mandriva and openSUSE but when it came to using ubuntu the steps that I was using to configure the modem failed.
here are the steps I use
modprobe usbserial vendor=0xXXXX 0xXXXX
where XXXX are the vendor id and product id obtained from the output of lsusb
then wvdialconf follwoed by wvdial after editing the /etc/wvdial.conf for username password and phone number.
but on ubuntu these steps fail to work.
wvdialconf ends in an error saying no modem found.
one more thing that I noticed was that in case of mandriva/opensuse wvdialconf used to check ttyS0 to ttyS9 or somehting but in ubuntu wvdialconf does not check beyond S4
please help me to get out of this.
