Hello, today I started more or less successfully the linux-next-kernel from 20120221. dmesg shows the following: [ 254.104161] usb 1-1: new high-speed USB device number 3 using ehci_hcd [ 254.221090] usb 1-1: New USB device found, idVendor=12d1, idProduct=1505 [ 254.221104] usb 1-1: New USB device strings: Mfr=3, Product=2, SerialNumber=0 [ 254.221115] usb 1-1: Product: HUAWEI Mobile [ 254.221123] usb 1-1: Manufacturer: Huawei Technologies [ 254.224621] scsi4 : usb-storage 1-1:1.0 [ 255.225685] scsi 4:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 0 [ 255.227083] scsi 4:0:0:0: Attached scsi generic sg1 type 5 [ 255.261902] sr0: scsi-1 drive [ 255.261916] cdrom: Uniform CD-ROM driver Revision: 3.20 [ 255.264286] sr 4:0:0:0: Attached scsi CD-ROM sr0 [ 258.384084] usb 1-1: usbfs: process 1304 (usb_modeswitch) did not claim interface 0 before use [ 258.390803] usb 1-1: USB disconnect, device number 3 [ 264.837159] usb 1-1: new high-speed USB device number 4 using ehci_hcd [ 264.954426] usb 1-1: New USB device found, idVendor=12d1, idProduct=1506 [ 264.954440] usb 1-1: New USB device strings: Mfr=4, Product=3, SerialNumber=0 [ 264.954451] usb 1-1: Product: HUAWEI Mobile [ 264.954459] usb 1-1: Manufacturer: Huawei Technologies [ 264.962453] scsi5 : usb-storage 1-1:1.5 [ 264.964426] scsi6 : usb-storage 1-1:1.6 [ 265.193127] usbcore: registered new interface driver usbserial [ 265.195179] USB Serial support registered for generic [ 265.196594] cdc_wdm 1-1:1.3: Ignoring extra header, type 15, length 13 [ 265.196605] cdc_wdm 1-1:1.3: Ignoring extra header, type 6, length 5 [ 265.197800] usbcore: registered new interface driver usbserial_generic [ 265.197811] usbserial: USB Serial Driver core [ 265.200234] cdc_wdm 1-1:1.3: cdc-wdm0: USB WDM device [ 265.200313] usbcore: registered new interface driver cdc_wdm [ 265.209773] USB Serial support registered for GSM modem (1-port) [ 265.211396] option 1-1:1.0: GSM modem (1-port) converter detected [ 265.212576] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB0 [ 265.212650] option 1-1:1.1: GSM modem (1-port) converter detected [ 265.213655] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB1 [ 265.213728] option 1-1:1.2: GSM modem (1-port) converter detected [ 265.215799] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB2 [ 265.215966] usbcore: registered new interface driver option [ 265.215973] option: v0.7.2:USB Driver for GSM modems [ 265.217447] qmi_wwan 1-1:1.4: Use "cdc_wdm" for QMI interface 1-1:1.3 [ 265.219735] qmi_wwan 1-1:1.4: wwan0: register 'qmi_wwan' at usb-0000:00:1d.7-1, QMI speaking wwan device, 00:a0:c6:00:00:00 [ 265.219847] usbcore: registered new interface driver qmi_wwan [ 265.966434] scsi 5:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 0 [ 265.967433] scsi 6:0:0:0: Direct-Access HUAWEI SD Storage 2.31 PQ: 0 ANSI: 2 [ 265.969649] sd 6:0:0:0: Attached scsi generic sg1 type 0 [ 265.971199] sd 6:0:0:0: [sdb] 31116288 512-byte logical blocks: (15.9 GB/14.8 GiB) [ 265.972232] sr0: scsi-1 drive [ 265.972702] sd 6:0:0:0: [sdb] Write Protect is off [ 265.972721] sd 6:0:0:0: [sdb] Mode Sense: 0f 0e 00 00 [ 265.973193] sr 5:0:0:0: Attached scsi CD-ROM sr0 [ 265.973775] sr 5:0:0:0: Attached scsi generic sg2 type 5 [ 265.974308] sd 6:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 265.982055] sdb: sdb1 [ 265.987586] sd 6:0:0:0: [sdb] Attached SCSI removable disk The change of the Device ID is caused by usb_modeswitch -v 12d1 -p 1505 -M "55534243123456780000000000000011062000000100000000000000000000" But now I am at the end. I can still put in at-command via minicom. But I don't know which. at+cgact=1 makes the LED blue. ( the color for a umts-connection) dhclient wwan0 timed out without results. ifconfig wwan0 up and ifconfig shows that: wwan0 Link encap:Ethernet HWaddr 00:A0:C6:00:00:00 inet6 addr: fe80::2a0:c6ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:49 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:15174 (14.8 Kb) Any hints?
