@Simon I just upgraded the kernel as Ubunutu 10.04 asked me to and redid the kernel module patching and installation as tnf described in comment #33. If the modem is not recognized I have to
$>sudo rmmod qcserial $>sudo modprobe qcserial $>sudo killall modem-manager to get it recognized and listed in the Networkmanager. Sometimes I am not able to unload the qcserial module, because of somekind of a circular reference between the the 3 (qcserial,usb_wwan, usbserial) modules. Also a $>killall modem-manager does not bring it up, but a reboot sometimes does the trick. But once recognized the connection is just fine (after I found out to use the Telefonica firmware) and responsive. I can establish a PPTP VPN connection to my server with out any problems and it even survives hibernation and an on/off cycle using the 'power switch' to turn on/off the wireless hardware (the switch on the right hand side right next to the eSata port). About the error you highlighted: I do not experience this behavior on my machine. For further investigation here are the stats of my machine. If there is anything else you need just let me know. $ ll 7xwc44ww.exe -rw-r--r-- 1 lapis lapis 31243392 2010-07-05 20:26 7xwc44ww.exe $ md5sum 7xwc44ww.exe 5d59b037c74559a2276aeb21cdf5b692 7xwc44ww.exe $ uname -a Linux trillian 2.6.32-24-generic-pae #39-Ubuntu SMP Wed Jul 28 07:39:26 UTC 2010 i686 GNU/Linux $ lsusb Bus 002 Device 003: ID 05c6:9204 Qualcomm, Inc.
