Hello Bjorn, Thank you very much for your reply. I followed your recommendation and used the proposed tarball. During compilation I've got some warnings: agrsoftmodem.c: In function 'x_task_queue_init': agrsoftmodem.c:458: warning: assignment from incompatible pointer type agrsoftmodem.c: In function 'x_task_queue_init_usb': agrsoftmodem.c:469: warning: assignment from incompatible pointer type agrsoftmodem.c: At top level: agrsoftmodem.c:496: warning: function declaration isn't a prototype agrsoftmodem.c:522: warning: function declaration isn't a prototype agrsoftmodem.c:532: warning: function declaration isn't a prototype agrsoftmodem.c:539: warning: function declaration isn't a prototype agrsoftmodem.c:135: warning: 'uss_driver' defined but not used WARNING: could not find /.../.agrmodemlib.o.cmd for /.../agrmodemlib.o The modules were generated and I tried to load them, but first with no success: FATAL: Error inserting agrmodem (/lib/modules/2.6.27.7-9-pae/kernel/drivers/char/agrmodem.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting agrserial (/lib/modules/2.6.27.7-9-pae/kernel/drivers/char/agrserial.ko): No such device The dmesg output was: agrmodem: module license 'Proprietary' taints kernel. agrmodem: disagrees about version of symbol snd_cards agrmodem: Unknown symbol snd_cards However, loading of the modules with modprobe can be forced by using the option "-f". dmesg output: agrmodem: no version for "struct_module" found: kernel tainted. agrmodem: module license 'Proprietary' taints kernel. *Hello Agere Driver** Loading module Agere Modem Controller driver version 2.1.80 (2008-10-31) ttyAGS3 at I/O 0x4 (irq = 217) is a AgereModem Loading module Agere Modem Interface driver version 2.1.80.0 (2008-10-31) I now tried wvdial and minicom to access the modem.
