>Description:
Support for USB_VENDOR_SIERRA USB_PRODUCT_SIERRA_USB305 devices was added
to both ugensa(4) and u3g(4) in PR #43468 ("Add Sierra Wireless USB 305
Support to ugensa device"). The corresponding USB PID 0x68a3 is also used
by newer devices like MC8704 and MC7700/MC7710 which provide several
serial ports like this (unsupported entries deleted):
at!udusbcomp=?
0 - HIP DM NMEA AT MDM1 MDM2 MDM3 MS SUPPORTED
2 - HIP DM NMEA AT NIC1 MS SUPPORTED
3 - HIP DM NMEA AT MDM1 NIC1 MS SUPPORTED
4 - HIP DM NMEA AT NIC1 NIC2 NIC3 MS SUPPORTED
5 - HIP DM NMEA AT ECM1 MS SUPPORTED
OK
Since ugensa(4) wins when attaching to the device and since it only
supports a single serial port the AT port for these devices is not
available.
>How-To-Repeat:
Connect a Sierra Wireless device with USB PID 0x68a3 which has several
serial ports (e.g. a MC7710 set to AT!UDPID=68a3) to a USB port and check
dmesg(1) output:
[ 346.1530744] ugensa0 at uhub5 port 2
[ 346.1530744] ugensa0: Sierra Wireless, Incorporated (0x1199) MC7710 (0x68a3), rev 2.00/0.06, addr 4
[ 346.1530744] ucom4 at ugensa0: Generic Serial Device

to the NetBSD 9.0 sources and rebuild the kernel. After reboot:

Now the HIP and DM ports are available but not the AT port.
This will be fixed in my u3g.c patch next.

PR kern/55329
Replace calls to usbd_device2interface_handle in u3g_match() and
u3g_attach() with the interface already passed in uiaa->uiaa_iface and
store the interface in sc->sc_iface for later use by u3g_open()/
Also skip Direct IP interfaces in u3g_match() to avoid potential side
effects.
