Public bug reported:
Running on Xenial and updated this morning.
If I plug in my ZTE WCDMA WWAN modem (USB ID 19d2:0031) while my laptop
is switched off, then power it on and log in then /sometimes/ it is
detected (once out of about 10 goes). If I plug it in after I've
already logged in it is yet to be detected correctly (tried about 10
times).
syslog.1.txt and usbmodeswitch.1.log are logs from boot up with the modem
attached.
If I run:
sudo usb_modeswitch -W -v 19d2 -p 0103 -K
(see manual.usb_modeswitch.log) then the modem is picked up and
available for use.
As a side note, in "Set up a Mobile Broadband Connection" I see two
modems: "ZTE WCDMA Technologies MSM" and also "zte_0".
