Hi all,
Has anyone had any success with getting a Huawei (Vodafone-branded)
K5161h 4G dongle working on OpenBSD?
It looks like it should work with the umb(4) driver, but the problem is
getting it into the right mode. When I plug it in, it appears as a USB
CD drive, and there are magic commands you can send to it to make it
appear either as an Ethernet interface (where it does NAT and DHCP for
you, should be supported by the cdce(4) driver) or as an MBIM device
plus three USB serial ports (which should be supported by umb(4) and
hopefully ucom(4)).
On FreeBSD and Linux, the mode switching is done by usb_modeswitch,
which supports switching it to either mode. usb_modeswitch compiles
fine on OpenBSD, but fails to actually send the magic command, and the
error code (from the usb_bulk_io function in libusb) says "unsupported
on this platform".
The other approach is to find a magic AT command that would switch it to
MBIM mode permanently, but I've failed to find anything online for this
model, and AT commands that I've found for other models don't work on
this one.
What it looks like in dmesg:
-----
umass0 at uhub0 port 1 configuration 1 interface 0 "HUAWEI_MOBILE
HUAWEI_MOBILE" rev 2.00/1.02 addr 2
umass0: using SCSI over Bulk-Only
scsibus3 at umass0: 2 targets, initiator 0

What usbdevs -v says:
-----

Look for default devices ...
Found devices in default mode (1)
Access device 002 on bus 000
Get the current device configuration ...
Current configuration number is 1
Use interface number 0
with class 8
Use endpoints 0x01 (out) and 0x81 (in)
Using alternative Huawei switching message
Looking for active drivers ...
Can't do driver detection on this platform.
Set up interface 0
Use endpoint 0x01 for message sending ...
Trying to send message 1 to endpoint 0x01 ...
Sending the message returned error -12. Try to continue
Read the response to message 1 (CSW) ...
Response reading failed (error -12)
Device is gone, skip any further commands
-> Run lsusb to note any changes. Bye!

I don't think it should make a difference, but I'm trying to do this on
the Octeon platform (EdgeRouter 6P).
Any ideas appreciated.
Many thanks,
Alex
