Not working on HP EliteBook 840 G5

[xentity]

Hi,

I'm using this notebook with Ubuntu 19.10, but still have no luck with the WWAN card.

I installed acpi-call-dkms via apt since I were not able to compile it.

Here is my USB tree:

If I run the command:

$ sudo ./xmm2usb 
Found XMM7360 modem at 0000:3b:00.0 (\_SB_.PCI0.RP07.PXSX)
Parent port is at 0000:00:1c.6
Disabling PCIe link...
OK!

and wait some time I get an unchanged USB tree. What can I do to use this modem (besides booting to Windows)?

Same issues on HP Elitebook 840 G8

$ sudo ./xmm2usb

But nothing.
