UHID(4) BSD Kernel Interfaces Manual UHID(4)
NAME
uhid — USB generic HID support
SYNOPSIS
To compile this driver into the kernel, place the following line in your
kernel configuration file:
device uhid
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
uhid_load="YES"
DESCRIPTION
The uhid driver provides support for all HID (Human Interface Device)
interfaces in USB devices that do not have a special driver.
The device handles the following ioctl(2) calls:
USB_GET_REPORT_ID (int)
Get the report identifier used by this HID report.
USB_GET_REPORT_DESC (struct usb_gen_descriptor)
Get the HID report descriptor. Copies a maximum of ugd_maxlen
bytes of the report descriptor data into the memory specified by
ugd_data. Upon return ugd_actlen is set to the number of bytes
copied. Using this descriptor the exact layout and meaning of
data to/from the device can be found. The report descriptor is
delivered without any processing.
struct usb_gen_descriptor {
void *ugd_data;
uint16_t ugd_maxlen;
uint16_t ugd_actlen;
uint8_t ugd_report_type;
...
};
USB_SET_IMMED (int)
Sets the device in a mode where each read(2) will return the cur‐
rent value of the input report. Normally a read(2) will only
return the data that the device reports on its interrupt pipe.
This call may fail if the device does not support this feature.
USB_GET_REPORT (struct usb_gen_descriptor)
Get a report from the device without waiting for data on the
interrupt pipe. Copies a maximum of ugd_maxlen bytes of the
report data into the memory specified by ugd_data. Upon return
ugd_actlen is set to the number of bytes copied. The
ugd_report_type field indicates which report is requested. It
should be UHID_INPUT_REPORT, UHID_OUTPUT_REPORT, or
UHID_FEATURE_REPORT. This call may fail if the device does not
support this feature.
USB_SET_REPORT (struct usb_gen_descriptor)
Set a report in the device. The ugd_report_type field indicates
which report is to be set. It should be UHID_INPUT_REPORT,
UHID_OUTPUT_REPORT, or UHID_FEATURE_REPORT. The value of the
report is specified by the ugd_data and the ugd_maxlen fields.
This call may fail if the device does not support this feature.
Use read(2) to get data from the device. Data should be read in chunks
of the size prescribed by the report descriptor.
Use write(2) to send data to the device. Data should be written in
chunks of the size prescribed by the report descriptor.
SYSCTL VARIABLES
The following variables are available as both sysctl(8) variables and
loader(8) tunables:
hw.usb.uhid.debug
Debug output level, where 0 is debugging disabled and larger val‐
ues increase debug message verbosity. Default is 0.
