OTG doesn't work on Z3735F tablet

Hi,
I've got a Z3735F tablet (model i783 A,an Android tablet sold in China.)
I installed Archlinux on micro SD card in QEMU and then boot it in the tablet's UEFI Shell.
I also plugged a keyboard through OTG,but the keyboard doesn't work.
Since my PC is also running Archlinux,I issued

zcat /proc/config.gz > /path/to/kernel/source/.config

and selected OTG Support from the menuconfig,built the kernel and ran it on my tablet.
But my keyboard still doesn't work.
Any suggestions?
Thanks.
(Using kernel 4.1.17-lts)
(I'm not a native English speaker.Please excuse me for my poor English...  )

There should be a BIOS style configuration tool in your UEFI. Find out how to launch it and review the OTG settings. Does the keyboard work in the UEFI shell?

There is almost nothing I can configure in the UEFI settings.
The OTG works both in UEFI Shell and Android.
I can use the adb shell but the root permission of Android is not available.
Is there anything I can do in the Android?
Thanks for your reply.
