Two months ago I asked for assistance with the installation of a Franklin U600 3G/4G modem on the above OS. Meanwhile I managed to get the 3G part of the dual modem to work reliably. I had to discover on my own that this modem does not work properly using usbserial - at least not on my Toshiba Satellite A45. Instead I am using the cdc_acm driver, which handles interrupt modems. Ever since I have had no switching problems on the 3G part. The modem actually does not require KPPP or wvdial to make a connection. The KDE network manager does that with 12.04; the Gnome network manager works better for 12.10. However, I am still unable to get the 4G modem to work. In fact, I still have to see the lsusb output that shows the Beceem modem identifiers. The best I have been able to do so far was to uncover a 'GSM' modem connected to a serial port that is almost immediately disconnected. According to the Sprint modem installation instructions the U600 is supposed to be detected upon insertion into a port. It is not. All I get on lsusb is: Bus 001 Device 005: ID 1fac:0151 cfg80211: All devices are disconnected, going to restore regulatory settings [ 2132.651330] cfg80211: Restoring regulatory settings [ 2132.651335] cfg80211: Calling CRDA to update world regulatory domain [ 2132.661306] cfg80211: Ignoring regulatory request Set by core since the driver uses its own custom regulatory domain [ 2132.661315] cfg80211: World regulatory domain updated: [ 2132.661317] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 2132.661320] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 2132.661323] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 2132.661326] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 2132.661329] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 2132.661331] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 2132.813437] wwan0: authenticate with 64:31:50:07:49:c0 [ 2132.824848] wwan0: send auth to 64:31:50:07:49:c0 (try 1/3) [ 2132.827801] wwan0: authenticated [ 2132.840044] wwan0: associate with 64:31:50:07:49:c0 (try 1/3) [ 2132.843822] wwan0: RX AssocResp from 64:31:50:07:49:c0 (capab=0x821 status=0 aid=9) [ 2132.844309] wwan0: associated [ 2244.959395] usbcore: deregistering interface driver usbbcm [ 2260.845212] usbcore: registered new interface driver usbbcm That is the 3G modem.

I must be missing something. Question: What am I missing? Where do I go wrong? Can anyone please tell me. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
