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:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 0
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 64
idVendor 0x413c Dell Computer Corp.
idProduct 0x81a3
bcdDevice 0.06
iManufacturer 1 Sierra Wireless, Incorporated
iProduct 2 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]: <debug> [1592288162.080686] (usbmisc/cdc-wdm0):
adding device at sysfs path:
/sys/devices/pci0000:00/0000:00:1d.0/usb3/3-1/3-1.6/3-
1.6:2.12/usbmisc/cdc-wdm0
ModemManager[7979]: <debug> [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?
Thank you,
Giuseppe
