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.
