Connect via ADB to a physical X86 via USB

[Alexandre Andrade]

Hi there,

I have Android-x86 (version 9.0-r2) running in a Lenovo MIIX-320 and I have another PC running Linux. 

From the Linux host I can connect to any other Android device using an USB cable. But I can't connect to the Lenovo. 

Googling around I noticed that the vast majority of people connect to Android-x86 host via ADB using the network, what is not an option in my case (for performance). 

Is there any service in the Android-x86 that I should use to allow ADB connections using USB?

Cheers,

Alex

first request hardware support dwc3 gadget.

Hi Youling,

I run:

# modprobe dwc3-pci

But 'lspci' doesn't show any new hardware:

Am I missing something?

Hi Youling,

This tittle Lenovo doesn't have that option on the BIOS.

But thank you very much for your support!

How do I request kernel configuration and userzone support from androidx86? I mean a terminal or how?

[Huy Minh Bùi (HMTheBoy154)]

I saw Celadon have     "mount configfs none /config"

Do I have to put it in ?

in the old android init.rc

    mount configfs none /config

    chmod 0775 /config/sdcardfs

    chown system package_info /config/sdcardfs
