Generic hid bus driver
Usage

Overview
The hidbus driver provides support for multiple HID driver attachments to single HID transport backend. See iichid(4) or usbhid(4).
Each HID device can have several components, e.g., a keyboard and a mouse. These components use different report identifiers (a byte) combined into groups called collections to distinguish which one data is coming from. The hidbus driver has other drivers attached that handle particular kinds of devices and hidbus broadcasts data to all of them.
Sysctl variables
The following variables are available as both sysctl(8) variables and loader(8) tunables:
- hw.hid.hidbus.debug
-
Debug output level, where 0 is debugging disabled and larger values increase debug message verbosity. Default is 0.
