Comment (by anonymous):
I've stumbled over "Failed to open device", too. However it now works for
me now even with autoconnect. According to memory I've released the
client-id ({{{uqmi -d /dev/cdc-wdm0 --release-client-id wds --set-client-
id wds,87}}}) and that made it work, if I remember correctly.
However I'm now having a hard time "properly" shutting down a network
connection (without pdh). As I understand the global PDH should help me
out (as in "{{{uqmi -d /dev/cdc-wdm0 --stop-network 4294967295
--autoconnect}}}"). "{{{uqmi -d /dev/cdc-wdm0 --stop-network 4294967295
--autoconnect}}}" doesn't give any output, but the connection is still
active. "{{{uqmi -d /dev/cdc-wdm0 --stop-network 4294967295}}}" yields
{{{"Invalid handle"}}}.
So it seems without "proper" pdh QMI is not allowing shutting down the
network ever.
I've resorted to "{{{rfkill block wwan; rfkill unblock wwan}}}" - not
pretty but at least works.
Btw: Is there somewhere documentation (like with state-diagrams) about QMI
to get a better understanding what needs (and can) be called when and
having which effect?
