Same problem in the Trusty beta that ships with MM 1.* The content from the USB-Modem (for the win and mac guys to install there software) is now displayed correctly but another error appears. I have attached a screenshot with the new error. Here the content of my syslog: Mar 31 11:12:35 ubuntu kernel: [ 180.559018] usb 2-1.3: new high-speed USB device number 5 using ehci-pci Mar 31 11:12:35 ubuntu kernel: [ 180.668513] usb 2-1.3: New USB device found, idVendor=12d1, idProduct=14fe Mar 31 11:12:35 ubuntu kernel: [ 180.668525] usb 2-1.3: New USB device strings: Mfr=2, Product=1, SerialNumber=0 Mar 31 11:12:35 ubuntu kernel: [ 180.668531] usb 2-1.3: Product: HUAWEI Mobile Mar 31 11:12:35 ubuntu kernel: [ 180.668536] usb 2-1.3: Manufacturer: HUAWEI Technology Mar 31 11:12:35 ubuntu kernel: [ 180.712007] usb-storage 2-1.3:1.0: USB Mass Storage device detected Mar 31 11:12:35 ubuntu kernel: [ 180.712160] scsi9 : usb-storage 2-1.3:1.0 Mar 31 11:12:35 ubuntu kernel: [ 180.712412] usb-storage 2-1.3:1.1: USB Mass Storage device detected Mar 31 11:12:35 ubuntu kernel: [ 180.712524] scsi10 : usb-storage 2-1.3:1.1 Mar 31 11:12:35 ubuntu mtp-probe: checking bus 2, device 5: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3" Mar 31 11:12:35 ubuntu mtp-probe: bus: 2, device: 5 was not an MTP device Mar 31 11:12:36 ubuntu kernel: [ 181.711693] scsi 10:0:0:0: Direct-Access HUAWEI TF CARD Storage 2.31 PQ: 0 ANSI: 2 Mar 31 11:12:36 ubuntu kernel: [ 181.711749] scsi 9:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 2 Mar 31 11:12:36 ubuntu kernel: [ 181.715076] sd 10:0:0:0: Attached scsi generic sg2 type 0 Mar 31 11:12:36 ubuntu kernel: [ 181.715623] sd 10:0:0:0: [sdc] Attached SCSI removable disk Mar 31 11:12:36 ubuntu kernel: [ 181.721877] sr0: scsi-1 drive Mar 31 11:12:36 ubuntu kernel: [ 181.722119] sr 9:0:0:0: Attached scsi CD-ROM sr0 Mar 31 11:12:36 ubuntu kernel: [ 181.722244] sr 9:0:0:0: Attached scsi generic sg3 type 5 Mar 31 11:12:36 ubuntu usb_modeswitch: switching device 12d1:14fe on 002/005 Mar 31 11:12:36 ubuntu kernel: [ 181.944879] usb 2-1.3: USB disconnect, device number 5 Mar 31 11:12:37 ubuntu kernel: [ 182.242952] usb 2-1.3: new high-speed USB device number 6 using ehci-pci Mar 31 11:12:37 ubuntu kernel: [ 182.336060] usb 2-1.3: New USB device found, idVendor=12d1, idProduct=1506 Mar 31 11:12:37 ubuntu kernel: [ 182.336072] usb 2-1.3: New USB device strings: Mfr=2, Product=1, SerialNumber=0 Mar 31 11:12:37 ubuntu kernel: [ 182.336078] usb 2-1.3: Product: HUAWEI Mobile Mar 31 11:12:37 ubuntu kernel: [ 182.336083] usb 2-1.3: Manufacturer: HUAWEI Technology Mar 31 11:12:37 ubuntu kernel: [ 182.338292] option 2-1.3:1.0: GSM modem (1-port) converter detected Mar 31 11:12:37 ubuntu kernel: [ 182.338452] usb 2-1.3: GSM modem (1-port) converter now attached to ttyUSB0 Mar 31 11:12:37 ubuntu kernel: [ 182.341055] huawei_cdc_ncm 2-1.3:1.1: MAC-Address: 0c:5b:8f:27:9a:64 Mar 31 11:12:37 ubuntu kernel: [ 182.341195] huawei_cdc_ncm 2-1.3:1.1: cdc-wdm0: USB WDM device Mar 31 11:12:37 ubuntu kernel: [ 182.341540] huawei_cdc_ncm 2-1.3:1.1 wwan0: register 'huawei_cdc_ncm' at usb-0000:00:1d.0-1.3, Huawei CDC NCM device, 0c:5b:8f:27:9a:64 Mar 31 11:12:37 ubuntu kernel: [ 182.341640] usb-storage 2-1.3:1.2: USB Mass Storage device detected Mar 31 11:12:37 ubuntu mtp-probe: checking bus 2, device 6: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3" Mar 31 11:12:37 ubuntu kernel: [ 182.343396] scsi11 : usb-storage 2-1.3:1.2 Mar 31 11:12:37 ubuntu kernel: [ 182.343708] usb-storage 2-1.3:1.3: USB Mass Storage device detected Mar 31 11:12:37 ubuntu kernel: [ 182.345577] scsi12 : usb-storage 2-1.3:1.3 Mar 31 11:12:37 ubuntu mtp-probe: bus: 2, device: 6 was not an MTP device Mar 31 11:12:37 ubuntu NetworkManager[1506]: SCPlugin-Ifupdown: devices added (path: /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.1/net/wwan0, iface: wwan0) Mar 31 11:12:37 ubuntu NetworkManager[1506]: SCPlugin-Ifupdown: device added (path: /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.1/net/wwan0, iface: wwan0): no ifupdown configuration found.
