After upgrading the system from Android 8 to Android 9, I cannot access "/sys/bus/usb/devices" any more.

I tried the following two method, but nether works: 1.Form C(Same as android_usbfs.c): DIR *dev = opendir("/sys/bus/usb/devices");

2.From Java: String[] names = (new File("/sys/bus/usb/devices")).list();

Both the two function above work under Android 8.0, is there anyone who knows how to solved it on Android 9.0? Thanks!
