Note that kbd-chooser also uses usbfs and contains this code (slightly
rewritten for demonstration) in kbd-chooser/usb-kbd.c:
fp = fopen ("/proc/bus/usb/devices", "r");
if (fp == NULL) { // try harder.
[...]
if system ("mount -t usbfs usbfs /proc/bus/usb") = 0) {
mounted_fs=1;
[...]
}
[...]
}
if (mounted_fs)
system ("umount /proc/bus/usb");
Which means that it looks if /proc/bus/usb/devices is already mounted and,
if not, mounts it. It's only unmounted afterwards if it was mounted by
this program.
IMO it would be better to standardize on this location.
