Watching for new files/symlinks/devices in sysfs (possible? which syscall?)

[Richard]

Hi,
is there a possibility, in sysfs, to watch for new symlinks (i.e. 
devices) beeing added to /sys/bus/usb/devices (like with inotify for 
normal directories)?

I know you can use select() (userspace) and sysfs_notify() (kernelspace) 
for attributes , but is there something for folders and new devices (or 
symlinks)?

Thanks,
