 **hid-decode** decodes one or more HID report descriptors into into
 human-readable format. It supports a variety of inputs:
 
-- a binary format as exported in sysfs, e.g.
-  _/sys/class/input/event0/device/device/report_descriptor_
 - the format exported by **hid-recorder(1)**
 - a _/dev/hidraw_ node
-- a _/dev/input/event_ node
 
 The format is deduced based on the input arguments. Undetected formats are
 assumed to be binary files.
