+%description
+This is a service that is built around the following kernel patch from:
+https://github.com/KarsMulder/Linux-Pollrate-Patch
+It allows to create a list of USB devices in 
+/etc/custom-device-pollrates/custom-device-pollrates.conf
+with different poll rate values. Once entries are added simply restart
+the service with `systemctl restart custom-device-pollrates.service`
+You can use a tool such as evhz (https://git.sr.ht/~iank/evhz) to check polling rates.
