USB_HID_SET_REPORT_REQUEST does not work correctly

dankarm — Sat, 13 Jun 2015 19:30:01 GMT

Using the latest Freescale Kinetis Software Development Kit (Kinetis SDK 1.2.0), discovered that the USB_HID_SET_REPORT_REQUEST
operation in the example application USB_App_Class_Callback() function (see hid_mouse or hid_keyboard demo_apps examples) does not work correctly. When the USB host sends a "Set Report" request, the "data" pointer referenced is always a NULL.

Investigating this, I determined that there appears to be a problem with the USB_Control_Service() function in the usb_framework.c file. In this function, the local "data" variable is always initialized to NULL and never changed before being passed to a callback function (eventually calling the application's USB_App_Class_Callback() function). I was able to get it to work by adding the following line: (shown in bold)

Line
448	/* class or vendor request */
449	size = event->len + USB_SETUP_PKT_SIZE;
	data = event->buffer_ptr;	// DLK added this bug fix
450	error = usb_fw_ptr->request_notify_callback(

Hi,

Hi Nicolas,

For these issues will be KSDK 1.3 Release Note, where you find known issues.

This version will be available with KSDK 1.3, by the end of Sep/beginning of Oct.

Hope this helps.
