One second latency ... not ideal.

Is there any way to sleepwait on a USB config change instead?

Add udev rule, to launch script when an input is connected:

   ACTION=="add", DEVPATH=="*/input/*", RUN+="/usr/local/bin/script.sh $devnode"

You can use `udevadm monitor` or venture into `dbus-monitor` to capture events from udev.
