Ok, let me try. I believe I should see the modem device on lsusb, but
I don't.

user@devuan:/sys/devices/platform/44000000.ocp/4a064000.usbhshost$
sudo lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
user@devuan:/sys/devices/platform/44000000.ocp/4a064000.usbhshost$
zcat /proc/config.gz | grep MAPPH
CONFIG_PHY_MAPPHONE_MDM6600=3Dy
user@devuan:/sys/devices/platform/44000000.ocp/4a064000.usbhshost$
zcat /proc/config.gz | grep OHCI_
CONFIG_USB_OHCI_LITTLE_ENDIAN=3Dy
CONFIG_USB_OHCI_HCD=3Dy
CONFIG_USB_OHCI_HCD_OMAP3=3Dy
CONFIG_USB_OHCI_HCD_PLATFORM=3Dy
user@devuan:/sys/devices/platform/44000000.ocp/4a064000.usbhshost$

As far as I can tell,

+CONFIG_USB_WDM=3Dy
+CONFIG_USB_SERIAL=3Dy
+CONFIG_USB_SERIAL_QUALCOMM=3Dy
+CONFIG_USB_SERIAL_WWAN=3Dy

should be enabled to enable the drivers (and I did that), but without
device showing on the bus...

Any ideas?

Best regards,
									Pavel
