Manuel, with the premise that I am no expert, the steps you followed are very similar to my case, this is the last msg of that thread http://linmodems.technion.ac.il/bigarch/archive-seventh/msg00575.html. (In this previous one you may find also the outputs of my system http://linmodems.technion.ac.il/bigarch/archive-seventh/msg00526.html). So, if in the output of 'sudo hsfconfig ----dumpdiag' you find lines similar to --- [17179987.384000] hda_codec: invalid dep_range_val 0:7fff [17179987.800000] cnxthsf_OsEventWaitTime(d9ef38e0/HDA CodecUnsolicitedmessage, 40): returning OSEVENT_WAIT_TIMEOUT --- and the commands --- sudo hsfstop; sudo hsfconfig -i --- don't work, then it means that also your modem is still not supported by Linuxant and as you see they still have no release date for the fix.
