Re: Sierra Wireless MC7455 umsm to umb

This class of devices can be in multiple configurations.

the OpenBSD driver doesn't have a way of changing the mode of the
device, either permanently or temporarily, and we also lack a way of
updating the firmware, which can also be desirable.

I've heard there is some Windows tooling that can do the job.
