I stumbled upon property "ro.usb.vid=2970" so anyone know what it means and where it gets stored in which file because it's not in build.prop or default.prop..?
What is this usb property
Question
Answer
A USB device has a Vendor ID and a Product ID for the host to distinguish a device model. Both are 2-bytes integer. That ro.usb.vid is exactly your device's USB VID. It is located at
/sys/class/android_usb/android0/idVendor
Use
cat in a terminal to read its value and echo to change it (effective until next boot).Also you can find your device's USB PID at
/sys/class/android_usb/android0/idProduct
which is likely named
ro.usb.pid in the same place. Again use cat and echo to access it.Q & A
