| USB_GET_REPORT_ID(Vt int) |
| | Get the report identifier used by this HID report. |
| USB_GET_REPORT_DESC(Vt "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 {
intsize;
u_char data[1024]; /* filled data size will vary */
};
|
| USB_SET_IMMED(Vt 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(Vt "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 report;
u_char data[1024];/* used data size will vary */
};
|
| USB_SET_REPORT(Vt "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. |
