USB devices wake laptop up on connect/disconnect

My USB devices wake my laptop up when I press a key. However, when I disconnect or connect the device, it also wakes up the laptop.

This is a problem, because when I leave my desk, I generally close the laptop (triggering suspend), then disconnect all wires to pack up the laptop. However, disconnecting the USB devices wakes the laptop up again. Because the laptop is closed, it's very very hard to realise it's woken up again.

Similarly, I might be sitting on the couch with the laptop, close it up, then plug it into a USB-C cable to charge. This also wakes it up.

Is it possible to still have a keypress on an external USB keyboard wake the laptop up, but a disconnect and connect not wake it up? Or is it all or nothing?
