Bug Description
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.
As a side note, in "Set up a Mobile Broadband Connection" I see two modems: "ZTE WCDMA Technologies MSM" and also "zte_0".
