33 To compile this driver into the kernel,
34 place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
41 Alternatively, to load the driver as a

44 .Bd -literal -offset indent
50 driver provides support for multiple HID driver attachments to single HID
57 Each HID device can have several components, e.g., a keyboard and
59 These components use different report identifiers (a byte) combined into
60 groups called collections to distinguish which one data is coming from.
63 driver has other drivers attached that handle particular
66 broadcasts data to all of them.
68 The following variables are available as both
73 .Bl -tag -width indent
74 .It Va hw.hid.hidbus.debug
75 Debug output level, where 0 is debugging disabled and larger values increase
