uhidev -- USB Human Interface Device support SYNOPSIS
uhidev* at uhub? ucycom* at uhidev? reportid ? uhid* at uhidev? reportid ? ukbd* at uhidev? reportid ? ums* at uhidev? reportid ? DESCRIPTION
The uhidev driver handles all Human Interface Devices. Each HID device can have several components, e.g., a keyboard and a mouse. These components use different report identifiers (a byte) to distinguish which one data is coming from. The uhidev driver has other drivers attached that handle particular kinds of devices and uhidev only dispatches data to them based on the report id. SEE ALSO

UHID(4) 						   BSD Kernel Interfaces Manual 						   UHID(4)

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_ctl_report_desc) Get the HID report descriptor. 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_ctl_report_desc { int ucrd_size; u_char ucrd_data[1024]; /* filled data size will vary */ }; USB_SET_IMMED (int) Sets the device in a mode where each read(2) will return the current 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_ctl_report) Get a report from the device without waiting for data on the interrupt pipe. The report 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. struct usb_ctl_report { int ucr_report; u_char ucr_data[1024]; /* used data size will vary */ }; USB_SET_REPORT (struct usb_ctl_report) Set a report in the device. The report field indicates which report is to be set. 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. 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. FILES
