Official bootloader unlock for ZenFone 2 is now available
Unlocking your bootloader allows you to put custom software onto your device. Many developers have created custom ROMs and have had to hack their way into the ZenFone 2 to make this available to powerusers in the community.
Now, unlocking the bootloader is as easy as downloading the utility, installing it, and running it.
Proceed with caution and read below notice before attempting

libhoudini: What It Means for Developers
libhoudini is a proprietary ARM translation layer for x86-powered Android devices. It allows an app that has NDK binaries for ARM, but not x86, to still run on x86 hardware, albeit not as quickly as it would with native x86 binaries.
Given ARM’s near-stranglehold on the Android ecosystem, libhoudini is hugely useful for Intel and hardware vendors interested in using Intel’s mobile CPUs. Without it, only apps that ship x86 NDK binaries would be compatible with x86-powered devices like the Samsung Galaxy Tab 3 10.1” tablet. Some developers probably skip x86 NDK binaries, because they are not aware of popular x86-powered devices, or lack one for testing, or are concerned over APK size. The Play Store for x86 would shrink substantially from the million-plus apps available to ARM devices, to those that do not use the NDK or happen to ship x86 binaries. libhoudini makes ARM-only NDK binaries usable on x86, giving x86-powered Android devices access to more of the Play Store catalog.

Kernel Support for miscellaneous (your favourite) Binary Formats v1.1
==============================================================
https://www.kernel.org/doc/Documentation/binfmt_misc.txt
This Kernel feature allows you to invoke almost (for restrictions see below)
every program by simply typing its name in the shell.
This includes for example compiled Java(TM), Python or Emacs programs.
To achieve this you must tell binfmt_misc which interpreter has to be invoked
with which binary. Binfmt_misc recognises the binary-type by matching some bytes
at the beginning of the file with a magic byte sequence (masking out specified
bits) you have supplied. Binfmt_misc can also recognise a filename extension
aka '.com' or '.exe'.
First you must mount binfmt_misc:
mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
Chrooting to: /opt/rootfs-armhf/
http://forum.slitaz.org/topic/chroot/page/3#post-26270
3. Mount the binfmt_misc handler
# modprobe binfmt_misc
# mount -t binfmt_misc binfmt_misc /proc/sys/fs/binfmt_misc
4. register our format with the kernel via the procfs
root@slitaz:~# echo ':arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\x00\xff\xfe\xff\xff\xff:/usr/bin/qemu-arm-static:' > /proc/sys/fs/binfmt_misc/register
5. check register

interpreter /usr/bin/qemu-arm-static

I am hopeing that I could ask favor from original post author 'gibor' I came this forum from google search I am searching for android usb OTG drivers for 'Qualcomm Technologies, Inc MSM8916' I see in first post that root access is made and the tablet has same processor and kernel version is same 'linux 3.10.49'
I would ask request if it is possible someone (gibor, or others is working on same tablet), post here or send copies of .ko module files in /system/lib/modules
I hope to try install modules and test with android vodafone smart prime 6 mobile phone and use the USB OTG device.

Sorry, but my tablet not have your kernel. My kernel is 3.0.36 (view first image on topic).
The kernel 3.10.49 view on post of alanyih, but I know nothing.
Offline
Ooops, sorry for confusion, I misread thread too quickly, I realise now you show me, I hope alanyih soon will come online and see request, unfortunately it seems forum does not have private message mail system.
I have been having crazy time trying to find drivers and still no luck, even more confusion trying to download cyanogen system images and mount with simg2img and loop mount showing filesystem larger than device.
It seems nowhere there is easy way to find usb OTG drivers for Hardware Qualcomm Technologies, Inc MSM8916.
I will keeps searching and hope that I will find help and solution.
Thank you gibor for your help and reply

Thank you very much for your time helping alanyih, very gracious, and I tried download as soon as I saw.
Unfortunately I think my assumptions and speed reading of thread led me to ask unnecessarily. I have check your archive and find there is no usb driver on your device.
I am starting to think maybe usb OTG driver is not available for MSM8916?.
I have already tried as you suggest test usbotgchecker, I edit android.hardware.usb.host.xml once I root device and checker shows usb enabled but no s3c driver.
To hack enable usb otg I follow this guide: https://github.com/452/USBHIDTerminal/wiki/How-to-enable-USB-host-API-support
Unfortunately I cannot find usb drivers and nothing is shown in /proc/ for device, no usb in /system/modules/ and nothing in dmesg. Pluging in OTG cable with power split has nothing in dmesg.
I think kernel maybe support MSM8916, maybe hardware or also some show software driver hack, but I cannot find ready compiled module and I am never compile kernel for android before.
I post question here : http://forum.xda-developers.com/android/help/root-requesting-root-alcatel-pop-2-5-t3106328/page8
I think I do not have enough time for many hours to understand kernel compile for android and not available /proc/config.gz in default android so my configuration is uncertain.
I will continue to search and post here if I find solution.
Many thanks for your attempt to help alanyih
