Snapdragon X55 (Thinkpad X1 Nano w/5G Modem)

[Oskar Stenman]

Hi!

I've tested it. ModemManager doesn't automatically activate it, hence the
relatively large ModemManager log (NetworkManager is spamming
activations).. But activating with qmicli works (although now with the new
command).

$ qmicli -p -d /dev/wwan0p2MBIM --device-open-mbim
--dms-foxconn-set-fcc-authentication=00
[20 May 2021, 15:22:51] -Warning ** [/dev/wwan0p2MBIM] couldn't detect
transport type of port: couldn't detect device driver
[20 May 2021, 15:22:51] -Warning ** [/dev/wwan0p2MBIM] requested MBIM mode
but unexpected transport type found
[/dev/wwan0p2MBIM] Successfully run Foxconn FCC authentication

I didn't check version before recompiling, but the binary is reporting as
1.17.1.
$ ModemManager --version
ModemManager 1.17.1
...
oskar at oskar-ThinkPad-X1-Nano-Gen-1:~$ which ModemManager
/usr/local/sbin/ModemManager
oskar at oskar-ThinkPad-X1-Nano-Gen-1:~$ ls -la /usr/local/sbin/ModemManager
-rwxr-xr-x 1 root root 7781472 May 20 14:55 /usr/local/sbin/ModemManager
oskar at oskar-ThinkPad-X1-Nano-Gen-1:~$ ps axu | grep ModemManager
root        1081  0.3  0.0 317800 15356 ?        Ssl  15:22   0:01
/usr/local/sbin/ModemManager --log-level DEBUG

So seems like the correct / newest version is running.
