Do you think it is 'bad' for the battery to be constantly checking /dev/input/event0 /dev/input/event1 /dev/input/event2 etc?
Plus I want the user to be able to remove the usb device and insert without problems, so the list of input event devices will be checked and repopulated every 10 seconds/30 seconds/1 minute.
I am happy to code this myself, but do you see any problems?
I'm just worried that this constant checking will impact the device somehow, I wouldn't want that.
Thanks for your work!

You need to use poll/select to read these events.
For hotplug, I think the best way to do so is using udev rules, however this requires modifying rootfs -- one thing I'm reluctant to do.
The daemon service itself use very little power/cpu if coding properly, the OTG device itself can be a power hog though.
