Hello,
OpenBSD 6.0 amd64
Device detected as umass (before "mode switch"), umsm and ugen (after).
After some manipulations with vendors/interfaces/protocols (on OpenBSD),
device is detected as cdce0, but dhclient is failed.
Serial ports (AT command ports) are detected and works fine.
AT^NDISDUP=1,1,"internet" is OK.

On FreeBSD, after manipulations like this, the device is detected as
cdce0 & ue0: <USB Ethernet> on cdce0
dhclient ue0 works fine.
My research in the source code has revealed some differences in
if_cdce.c file
https://github.com/freebsd/freebsd/blob/master/sys/dev/usb/net/if_cdce.c
FreeBSD version has many lines of code grouped by CDCE_HAVE_NCM option:
#if CDCE_HAVE_NCM
static usb_callback_t cdce_ncm_bulk_write_callback;
static usb_callback_t cdce_ncm_bulk_read_callback;
#endif
and many more like this
If I got it right, in Linux the same function is performed this way:
cdc_ncm
http://lxr.free-electrons.com/source/drivers/net/usb/cdc_ncm.c?v=3.13
or this way:
huawei_cdc_ncm
http://lxr.free-electrons.com/source/drivers/net/usb/huawei_cdc_ncm.c?v=3.13
I read
http://openbsd-archive.7691.n7.nabble.com/Driver-Request-Huawei-MU609-Cellular-Modem-td269924.html
It’s seems to be the same problem here.
I know about "ppp" mode (AT+CGDCONT=1,....),
device works properly by this way, but the speed (in comparison to
FreeBSD/Ubuntu AT^NDISDUP mode) decreased by ~30% and latency decreased
by ~20%.
It would be great if a nice developer could add support for this kind of
devices.
Probably, E3272, E3276 and many other Huawei devices are the same...

at first access to /dev/cuaU1 this king of messages appear in dmesg, but
/dev/cuaU1 works fine:

Please send your dmesg to <b...@openbsd.org>, thanks.
