There is one Linux distro having support for : 0x11c11040 chip modems on HDA cards Red Flag Linux http://www.redflag-linux.com/eindex.html for Kernel 2.6.21.0-22 provides a binary package supporting 0x11c11040 on HDA cards, Agere-driver-1.0-10dd.i386.rpm containing compiled agrmodem + agrserial After installing the kernel-2.6.21.0-22.rpm package from Red Flag Linux , Agere-driver-1.0-10dd.i386.rpm is supported : http://wiki.opennet.ru/hp6510b You can Google search with: Agere-driver-1.0-10dd.i386.rpm Then Google will translate the Agere-driver-1.0-10dd.i386.rpm from Russian ( which I'll also append below) I'm currently trying some tests, that may provide a route around a full Red Flag Linux installation and will report on this later.

He's HP notebook user. There's 0x11c11040 onboard modem. He found out that Red Flag Linux HP customer service centre (some Chinese company) provides linux driver for it but already built for some chinese linux distribution. This means its not workable for other kernels. Google "agere-driver-1.0-10dd.i386.rpm" to see details. Basically it agere-modem/serial pair with wellknown core agrmodemlib.o but its newer version 2.1.80. While we had 2.1.73 Regards, A. Chentsov
