When I enable adb on my AOSP 9 imx6q device, on my Linux development host this happens:
'lsusb' output on my Linux laptop connected to the device via OTG-microUSB port:

On my Samsung phone, I have to enable USB debugging using special instructions before it can be used by ADB. I tried doing that by changing device.mk so that my /system/build.prop has the following entries:
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb
But the device doesn't show up in 'adb devices' .
TCP(ethernet) based adb connection works just fine.What else should I check and enable?
