Hi! I am trying to get this thing working.
Debian 8.8 on Lenovo ThinkPad X220 Originally, Linux seems to detect the thing but then does nothing with it. dmesg: ################################################## [ 1.950070] usb 2-1.4: config 1 has an invalid interface number: 7 but max is 5 [ 1.950079] usb 2-1.4: config 1 has no interface number 5 [ 1.952051] usb 2-1.4: New USB device found, idVendor=1199, idProduct=68a3 [ 1.952070] usb 2-1.4: New USB device strings: Mfr=3, Product=2, SerialNumber=4 [ 1.952075] usb 2-1.4: Product: MC7710 [ 1.952080] usb 2-1.4: Manufacturer: Sierra Wireless, Incorporated [ 1.952084] usb 2-1.4: SerialNumber: 358178040028229 ################################################## ifconfig doesn't list any wwan0, no /dev/ttyUSB* exists. So after a lot of searching I found this forum post: https://ubuntuforums.org/showthread.php?t=2121838 User bmork created a udev rule there which appearently works for the Ubuntu guy over there. So I copied the rule and created it for me as well. I'm copying it here just in case: ################################################## ACTION!="add|change", GOTO="mbim_to_qmi_rules_end" SUBSYSTEM!="usb", GOTO="mbim_to_qmi_rules_end" # ignore any device with only one configuration ATTR{bNumConfigurations}=="1", GOTO="mbim_to_qmi_rules_end" # force Sierra Wireless MC7710 to configuration #1 ATTR{idVendor}=="1199",ATTR{idProduct}=="68a2",ATTR{bConfigurationValue}="1" LABEL="mbim_to_qmi_rules_end" ################################################## Now dmesg says a few more things after a reboot: ################################################## [ 1.950070] usb 2-1.4: config 1 has an invalid interface number: 7 but max is 5 [ 1.950079] usb 2-1.4: config 1 has no interface number 5 [ 1.952051] usb 2-1.4: New USB device found, idVendor=1199, idProduct=68a3 [ 1.952070] usb 2-1.4: New USB device strings: Mfr=3, Product=2, SerialNumber=4 [ 1.952075] usb 2-1.4: Product: MC7710 [ 1.952080] usb 2-1.4: Manufacturer: Sierra Wireless, Incorporated [ 1.952084] usb 2-1.4: SerialNumber: 358178040028229 <snip> [ 6.549427] usbcore: registered new interface driver usbserial [ 6.549437] usbcore: registered new interface driver usbserial_generic [ 6.549445] usbserial: USB Serial support registered for generic [ 6.550227] usbcore: registered new interface driver sierra [ 6.550235] usbserial: USB Serial support registered for Sierra USB modem [ 6.550251] sierra 2-1.4:1.0: Sierra USB modem converter detected [ 6.550748] usb 2-1.4: Sierra USB modem converter now attached to ttyUSB0 [ 6.550765] sierra 2-1.4:1.1: Sierra USB modem converter detected [ 6.551106] usb 2-1.4: Sierra USB modem converter now attached to ttyUSB1 [ 6.551121] sierra 2-1.4:1.2: Sierra USB modem converter detected [ 6.551476] usb 2-1.4: Sierra USB modem converter now attached to ttyUSB2 [ 6.551491] sierra 2-1.4:1.3: Sierra USB modem converter detected [ 6.551895] usb 2-1.4: Sierra USB modem converter now attached to ttyUSB3 [ 6.551908] sierra 2-1.4:1.4: Sierra USB modem converter detected [ 6.552328] usb 2-1.4: Sierra USB modem converter now attached to ttyUSB4 [ 6.553662] systemd-udevd[283]: starting version 215 [ 6.556804] sierra_net 2-1.4:1.7 wwan0: register 'sierra_net' at usb-0000:00:1d.0-1.4, Sierra Wireless USB-to-WWAN Modem, 36:74:99:5c:01:07 [ 6.558933] usbcore: registered new interface driver sierra_net <snip> [ 9.855501] usb 2-1.4: USB disconnect, device number 3 [ 9.855593] sierra ttyUSB2: resubmit read urb failed.(-19) [ 9.855842] sierra ttyUSB1: resubmit read urb failed.(-19) [ 9.856130] sierra ttyUSB0: Sierra USB modem converter now disconnected from ttyUSB0 [ 9.856142] sierra 2-1.4:1.0: device disconnected [ 9.856288] sierra ttyUSB1: Sierra USB modem converter now disconnected from ttyUSB1 [ 9.856298] sierra 2-1.4:1.1: device disconnected [ 9.856843] sierra ttyUSB2: Sierra USB modem converter now disconnected from ttyUSB2 [ 9.856854] sierra 2-1.4:1.2: device disconnected [ 9.856967] sierra ttyUSB3: Sierra USB modem converter now disconnected from ttyUSB3 [ 9.856980] sierra 2-1.4:1.3: device disconnected [ 9.857091] sierra ttyUSB4: Sierra USB modem converter now disconnected from ttyUSB4 [ 9.857104] sierra 2-1.4:1.4: device disconnected [ 9.860717] sierra_net 2-1.4:1.7 wwan0: unregister 'sierra_net' usb-0000:00:1d.0-1.4, Sierra Wireless USB-to-WWAN Modem [ 9.909695] sierra_net 2-1.4:1.7 (unregistered net_device): usb_control_msg failed, status -19 ################################################## So, now ttyUSB{1..4} are being created, the drivers are being loaded and everything, but shortly after during the booting process the "USB" device (it's actually mSATA) disconnects. Has someone an idea what's going on? What am I missing? -- 4096R/1224DBD299A4F5F3 47BC 7DE8 3D46 2E8B ED18 AA86 1224 DBD2 99A4 F5F3
