Scrcpy mouse input modes don't work in my specific case...

[Marietto2008]

Hello again.

I read that scrcpy has a few keyboard and mouse only modes. I've thought : maybe at least one of those modes works.

I've google a little bit and I found this thread :

https://android.stackexchange.com/questions/253317/how-to-connect-mouse-to-android-phone-via-adb

This is the post that caught my attention :

I figured a way out how to do it with :

https://github.com/Genymobile/scrcpy/blob/master/doc%2Fhid-otg.md#physical-mouse-simulation :

Get scrcpy from your package manager
Connect adb
scrcpy --hid-mouse or scrcpy -M for short

So,I've decided to try. First of all,this link :

https://github.com/Genymobile/scrcpy/blob/master/doc%2Fhid-otg.md#physical-mouse-simulation

is dead,but no problem,the working one is this :

https://github.com/Genymobile/scrcpy/blob/master/doc/mouse.md

I tried all the modes supported by scrcpy :

1)

No error here,but the mouse does not move inside the VM.

Any method to fix the Permission denied error ?

Any method to fix the Permission denied error ?

Run a newer version of Android, 7.1.1 is too old for UHID with shell permissions.

I can't use another VM : this is a special version of Android...

By rooting the VM,I will fix the problem ? This version of Android has the gearlock recovery mode :

https://github.com/axonasif/gearlock

so,I suspect that I can root it...
