Hi
Thank for the reply, i am writing an HID driver ,
and i would like to know if there HID API i can use inorder to poll
the interrupt endpoint.
see below the function
struct hid_report *report;
struct list_head *report_list =
&hid->report_enum[HID_FEATURE_REPORT].report_list;
if (list_empty(report_list)) {
return -ENODEV;
}
report = list_first_entry(report_list, struct hid_report, list);
if (report->maxfield < 1)
return -ENODEV;
list_for_each_entry(report,report_list, list) {
if (report->maxfield < 1) {
continue;
}
switch (report->id) {
case DRIVER_ALIVE:
usbhid_submit_report(hid, report, USB_DIR_OUT);
break;
case GET_VERSION:
usbhid_submit_report(hid, report, USB_DIR_OUT);
//TODO In this stage i need to read the answer from Interrupt ENDPOINT
break;
}
}
}
