Or rather, it works insofar as I can issue AT commands and get
responses. Once I (or pppd) make it connect (i.e., ATD*99***1#), I get
nothing else out of it. I'm not sure if it's something I'm doing wrong
that's not related to the driver.
Curiously, it appears as two umsm(4) devices, but only one ucom(4):
-----
umsm0 at uhub0 port 1 configuration 1 interface 0 "HUAWEI_MOBILE HUAWEI_MOBILE"
rev 2.00/1.02 addr 2
ucom0 at umsm0
umsm1 at uhub0 port 1 configuration 1 interface 1 "HUAWEI_MOBILE HUAWEI_MOBILE"
rev 2.00/1.02 addr 2

Is it possibly one of those devices mentioned in the umsm(4) manpage
that requires multi-link operation, but the umsm(4) driver is only
seeing one of the serial ports? In MBIM mode, it presents three serial
ports.
In any case, I think the right answer is to make it work with umb(4).
I'll see if I can make any progress with this.
