with udc being attatched to UVC, how can ADB be used?

[neo2014]

I am working on lf-5.15.y branch and imx8mp, and I added ADB.

But the log "

udc-core: couldn't find an available UDC or it's busy" is printed and android-tools-adbd.service failed to execute.

Anyway, I noticed UVC is attached to udc and after disabling UVC , I succeeded to ADB working.

How can I use ADB and UVC?

Hi @neo2014,

I hope you are doing well.

The UDC controller driver can support any number of different gadget drivers, but only one of them can be used at a time. So when we enable the uvc functionality we lose the adb access.

One can try using adb over network setup (e.g. wifi, ethernet).

Please refer to below community threads for more information.
