Sierra Wireless EM7345 4G LTE here. This devices currently attached
as umodem(4). But I did add its vendor id and device id to umb_devs,
which makes it partially attach:
umb0 at uhub0 port 4 "Sierra Wireless Inc. Sierra Wireless EM7345 4G LTE" rev
2.00/17.29 addr 2
umb0: switching to config #1
umb0: ignoring invalid segment size 1500
umb0: ctrl_len=512, maxpktlen=8192, cap=0x4
umb0: no control interface found
(this is with UMB_DEBUG enabled)
It seems this device needs some additional poking to select alternate
interface settings. Currently playing around with that. But in case
you're curious, the lsusb -v output for this device is:
