My OTG was working fine on my device before. But from some time I am not able to mount OTG (I did change ROM's in between). OTG is not detected in TWRP (I'm using this TWRP ) nor it is detected inside the OS.
Has anyone faced this before? Can anyone help me with it.
PS. I have included the android.hardware.usb.host.xml file. My device didn't have the file tablet_core_hardware.xml or handheld_core_hardware.xml .
But I manually added those files. Still with no luck.

Problems with WiFi & Recovery with rk3036 board used in Mega Drive Flashback Consol
Hi guys,
I am a (bad) developer who is trying to obtain the maximum from the recently released Mega Drive Flashback console.
It is an Android 4.4.4 unit with an rk3036 SoC. The problems I am facing are 2:
1 - WiFi module seems not to be laoded and all .ko modules present in /system/lib/modules give "invalid exec format" for the exception of the mali.ko (gpu) one (when instmod it says "already present"). I would like to know what I have to do to find/build a correct wifi module; reading on the web it seems to be a kernel-related problem so I need to recompile the .ko or find another kernel or find a precompiled .ko which "fits" with the used kernel. I found other kernel.img, system.img and boot.img from other Rockchip devices but I do not know which .ko file to "reuse" (wifi.ko ?). Which WiFi USB dongle do you suggest me for this "challenge" ?
2 - I "stole" a TWRP 3.1.1 from an Android TV firmware using another Rockchip SoC and it is booting fine (I cannot control it via touch screen because the Mega Drive Flashback has not a screen but it is controllable via mouse) but it seems not to recognize/mount any console partition and the mounted ones (the ones present inside the recovery) are 0 bytes and I cannot save options. Can someone help me in making this recovery in a working state ? If needed I can post the recovery.img file.
The device is correctly rooted with SuperSU and has Busybox installed. ADB and MTP drivers are working fine.
Sorry for all those noob questions but we are trying to describe how the console works; you can find what we found out here: https://mdfbrew.org.

and then modified the directory to (/sys/devices/platform/ff100000.hisi_usb/plugusb) but again nothing happens !

Download Elite kernel 2.1.zip,
https://mega.nz/file/YtUgzLaB#fIo23EtM6NlgxZoxN023raDuo7GzNUiI6uJJMI8Qp28
flash it in TWRP, wipe dalvik/art cache , reboot. Backup your stock boot.img!
But if I remember correctly, OTG may not work properly with Magisk. So use SuperSu 2.7.9 or 2.8.2 (uninstall Magisk first!).
worked like a charm ! don't know how to thank you
