"port not candidate" error message with DELL Wireless 5570 (aka Sierra Wireless AirPrime 7W5P6)
Hello to all, I am not at all an expert of modem manager but I hope this is the right place where to post my question. I am trying to use a WWAN module on a laptop. The module is named "Dell Wireless 5570 HSPA+ (42Mbps) Mobile Broadband Card" (a.k.a. Sierra Wireless AirPrime 7W5P6). It is listed like this: $ lsusb --verbose -d 413c: | head -17 Bus 003 Device 003: ID 413c:81a3 Dell Computer Corp. Device Descriptor: bLength18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize064 idVendor 0x413c Dell Computer Corp. idProduct 0x81a3 bcdDevice0.06 iManufacturer 1 Sierra Wireless, Incorporated iProduct2 Dell Wireless 5570 HSPA+ (42Mbps) Mobile Broadband Card iSerial 3 bNumConfigurations 2 The card is not used by modemmanager, in fact I does write: ModemManager[7979]: [1592288162.080686] (usbmisc/cdc-wdm0): adding device at sysfs path: /sys/devices/pci:00/:00:1d.0/usb3/3-1/3-1.6/3- 1.6:2.12/usbmisc/cdc-wdm0 ModemManager[7979]: [1592288162.080759] (usbmisc/cdc-wdm0): port not candidate This happens even if I run ModemManager after putting the card online with this command: $ sudo qmicli -d /dev/cdc-wdm0 --dms-set-fcc-authentication and checking the results this way: $ sudo qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode [/dev/cdc-wdm0] Operating mode retrieved: Mode: 'online' HW restricted: 'no' Is it possible to use modemmanager for managing this card?
