Only the exact same devpath uevent can launch external handler specified in ueventd.rc. So, you should specify all possible devpaths, even firmware with different filenames on the same device. Pattern mactching can be used to simplify this. Test: atest CtsInitTestCases Signed-off-by: Suchang Woo <suchang.woo@samsung.com> Change-Id: If3b7a2cabb8055bf4b768d928f0fc0012da3c177
