I'm trying to get an LTE card working in MBIM mode with the umb device
driver, but it just keeps saying "SIM not initialized PIN required". The
SIM isn't PIN locked, as far as I know the SIM has no PIN. I've tested
the card and SIM under linux on the exact same system and was able to
get it working fine just by supplying the APN.
The card is a Sierra Wireless MC7455; to get it working with the umb
driver I did have to disable the umsm driver as for some reason that one
claimed it first. Once that driver was disabled the umb driver seemed
happy with it:
umb0 at uhub2 port 3 configuration 1 interface 12 "Sierra Wireless,
Incorporated Sierra Wireless MC7455 Qualcomm\M-. Snapdragon? X7 LTE-A" rev
2.10/0.06 add r 3
ugen0 at uhub2 port 3 configuration 1 "Sierra Wireless, Incorporated Sierra
Wireless MC7455 Qualcomm\M-. Snapdragon? X7 LTE-A" rev 2.10/0.06 addr 3
After boot, the interface looked like:
umb0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
index 6 priority 0 llprio 3
roaming disabled registration unknown
state down cell-class none
SIM not initialized PIN required
status: down
I set the APN and tried to bring it up:
umb0: flags=8811<UP,POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
index 6 priority 0 llprio 3
roaming disabled registration unknown
state down cell-class none
SIM not initialized PIN required
APN r.ispsn
status: down
But it still just says the SIM is not initialized. After a minute or two,
it starts logging these to the console:
umb0: state change timeout
umb0: state change timeout
umb0: state change timeout
umb0: state change timeout
Am I missing something? This card isn't listed explicitly as being
compatible, is there a problem with the driver and this particular card?
Under linux, the serial control interfaces were available as USB devices
so you could poke at the card with AT commands, I don't see any listed
booted under openbsd. The umb driver doesn't support accessing the card
directly for debugging and diagnostics?
Thanks...
