Finally! (more detail than other work arounds, will be completed - this doc is still in process) Getting it work can be tricky if your stick must be activated, here my solution works for ZTE MF 823 (1und1 surfstick). It take a lot of time to figure out how to get the stick work, so i will share my experiences with you! Kernel used:4.4.6 You HAVE to disable your current connections! on my system, guess the connections will go down by switching?:ifconfig enp2s0 down
ifconfig wlp3s0 down
or so, will do this ... initemerge --ask wvdial && emerge --ask kppp && emerge --ask usb_modeswitch
Kernel Config;
Device Drivers --->
[*] Network device support --->
<*> PPP (point-to-point protocol) support
[*] PPP filtering
<*> PPP support for async serial ports
<*> PPP support for sync tty ports
<*> PPP Deflate compression
<*> PPP BSD-Compress compression
[*] USB support --->
[M] USB Serial Converter support --->
[M] USB Serial Console device support
<*> USB driver for GSM and CDMA modems
compile kernel and add to bootloader, reboot start ppp
Add user to group:
gpasswd -a username uucp
(eg dialout on other distros)
init:
lsusb:
Bus 003 Device 008: ID 19d2:1225 ZTE WCDMA Technologies MSM
for detailed info use:
lsusb -v -d 19d2:1225
(1403 is not modem mode!)
1. to be sure add all modes ...
modprobe option
echo "19d2 1225" | tee /sys/bus/usb-serial/drivers/option1/new_id
modprobe option
echo "19d2 1403" | tee /sys/bus/usb-serial/drivers/option1/new_id
modprobe option
echo "19d2 1405" | tee /sys/bus/usb-serial/drivers/option1/new_id
2.after plugin your stick run:modprobe usbserial
3. will work out of the box if configured:usb_modeswitch -v 19d2 -p 1225 -K
usb_modeswitch -v 19d2 -p 1405 -W -H
succesfully switched your devices should be recognized as 19d2:1405
and ls /dev/ttyS0 not /dev/ttyUSB1 must be present. The stick is recognized as ethernet connection in your system!

WOW! This is headway:

When everything is fine you should be able to connect to http://192.168.0.1 ! enter your pin and have fun ....

after reboot modprobe usbserial is enough to connect on my system, when a udev rule is specified jump to udev.
add modules="usbserial"to /etc/conf.d/modules to load it on default runlevel.
Connect
unstable!
Optional:
You can choose usb_modeswitch with static conf too:
add this lines to: /etc/usb_modeswitch.conf:
HuaweiMode=1
NeedResponse=0
DefaultVendor=0x19d2
DefaultProduct=0x1225
TargetVendor=0x19d2
TargetProduct=0x1405
#MessageEndpoint=0x04

for switching use:usb_modeswitch -c /etc/usb_modeswitch.conf
