Cinterion MV31-W modem support

[ROSTANSKI Tomasz]

Hi,

We do have a Cinterion MV31-W PCIe (MHI) modem (SGX55 based) and would like to use Modem Manager to control it.
We have mhi, mhi_pci_generic, mhi_net and mhi_wwan_ctrl modules loaded. The modem is detected, /dev/wwan0at0 and /dev/wwan0mbim0 devices are created,
mhi_mbim0 network interface is present.
The modem is visible on PCI bus with vendor id 0x1269 and device id 0x00b3.
The first thought was that we have to whitelist the vendor id in the Modem Manager, but it doesn't seem to help.
Any guidelines will be really appreciated.

Thank you,
Tomasz
