Hello fellow I have a modem with Agere chip "11c11040-HDA" in an Acer Aspire 4730z. >From this direction "http://linmodems.technion.ac.il/packages/ltmodem/11c11040" download file "agrsm-20080626.tar.gz" and follow the steps to install Kubuntu 9.04 32 bits but it never qe already can not find the path "/ usr / src / linux / sound / pci / hda / hda_codec.c" which indicates a step in the manual. I have seen that there are some packages "deb" but for previous versions of my kernel. Someone can tell me if you plan to take a kernel Kubuntu 9.04 32-bit or know any other way to install this modem Greetings from Mexico.
