Hi,
Do the USB interfaces show up long before the modem is ready to accept
AT commands? Or do the AT commands take a long time to complete?
The USB shows up long before the modem is ready to accept AT commands,
and - if supported - the MBIM OPEN takes a long time to complete.
So you really need to have a serious talk to your firmware guys about
fixing this. Why is the modem jumping on the bus before it is ready to
accept AT commands?
In my 10+ years I've never seen a modem do this. Some take 5 seconds,
maybe 10. I've never seen anything more than that, which is why that 20
second value was quite conservative when I added it.
Anyhow, go ahead and add ofono_modem_set_powered_timeout_hint(unsigned
int seconds) and have udevng detection fix this.
