I just bought a new laptop, HP EliteBook 840 G2. I used this computer during my travel in a train. I bought this laptop, because it has a 4G modem integrated. This modem works on Windows, but I can't use it on Linux.
I did what was explained in the doc.
lsusb found the module :
Bus 002 Device 027: ID 03f0:8e1d Hewlett-Packard
When I tried to setup the modem with
systemctl status ModemManager
it showed me this error:
Couldn't find support for device at '/sys/devices/pci0000:00/0000:00:14.0/usb2': not supported by any plugin
How I can setup my modem on ArchLinux ?
