I cannot explain why ModemManager doesn't see the udev tags, a bit of a mistery. If the tags are there, and reported correctly by udevadm, why does MM not see them? Could you build and run the "lsudev" tool in the ModemManager sources (under /test) and run it like this? $ sudo ./lsudev wwan Also, the log you posted is not from MM 1.18.4, it looks a modified versin. I cannot find a reason to explain how this line is generated: ModemManager[32336]: <debug> [000001804.593237] [filter] registered plugin whitelist vendor id: 17cb Can you test with 1.18.4 unmodified? -- Aleksander https://aleksander.es
