Hi,
i am developing a device with nordic NRF52840 soc and i want to implement a usb device with HID interface and custom hid descriptor, for test i changed nordic usb_hid_generic example as below:
#define USBD_CUSTOM_REPORT_DESCRIPTOR { \
0x06, 0xD0, 0xF1 , /*USAGE_PAGE (FIDO Alliance) */ \
0x09, 0x01 , /* USAGE (U2F HID Authenticator Device) */ \
0xa1, 0x01 , /* COLLECTION (Application) */ \
0x09, 0x20 , /* USAGE (Input Report Data) */ \
0x15, 0x00 , /* LOGICAL_MINIMUM (0) */ \
0x26, 0xff, 0x00 , /* LOGICAL_MAXIMUM (255) */ \
0x75, 0x08 , /* REPORT_SIZE (8) */ \
0x95, 0x40 , /* REPORT_COUNT (64) */ \
0x81, 0x02 , /* INPUT (Data,Var,Abs) */ \
0x09, 0x21 , /* USAGE(Output Report Data) */ \
0x15, 0x00 , /* LOGICAL_MINIMUM (0) */ \
0x26, 0xff, 0x00 , /* LOGICAL_MAXIMUM (255) */ \
0x75, 0x08 , /* REPORT_SIZE (8) */ \
0x95, 0x40 , /* REPORT_COUNT (64) */ \
0x91, 0x02 , /* OUTPUT (Data,Var,Abs) */ \
0xc0 , /* END_COLLECTION */ \
}
APP_USBD_HID_GENERIC_SUBCLASS_REPORT_DESC(custom_desc,USBD_CUSTOM_REPORT_DESCRIPTOR);
static const app_usbd_hid_subclass_desc_t * custom_reps[] = {&custom_desc};
#define CUSTOM_HID_GENERIC_INTERFACE 0
/**
* @brief HID generic class endpoint number.
* */
#define HID_GENERIC_EPIN1 NRF_DRV_USBD_EPIN2
#define HID_GENERIC_EPOUT1 NRF_DRV_USBD_EPOUT2
#define REPORT_IN_QUEUE_SIZE1 1
/**
* @brief Size of maximum output report. HID generic class will reserve
* this buffer size + 1 memory space. */
#define REPORT_OUT_MAXSIZE1 63
/**
* @brief HID generic class endpoints count.
* */
#define HID_GENERIC_EP_COUNT1 1
/**
* @brief List of HID generic class endpoints.
* */
#define ENDPOINT_LIST1() \
( \
HID_GENERIC_EPIN1,HID_GENERIC_EPOUT1 \
)
void hid_user_ev_handler1(app_usbd_class_inst_t const * p_inst,
app_usbd_hid_user_event_t event);
/**
* @brief Global HID generic instance
*/
APP_USBD_HID_GENERIC_GLOBAL_DEF(ctap_hid_generic1,
CUSTOM_HID_GENERIC_INTERFACE,
hid_user_ev_handler1,
ENDPOINT_LIST1(),
custom_reps,
REPORT_IN_QUEUE_SIZE1,
REPORT_OUT_MAXSIZE1,
APP_USBD_HID_SUBCLASS_NONE,
APP_USBD_HID_PROTO_GENERIC);
as you can see i changed the endpoints to 2 and also i changed the mouse descriptor to another one. in main function i try to add the class to the stack as below:
ret = app_usbd_init(&usbd_config); APP_ERROR_CHECK(ret); app_usbd_class_inst_t const * class_inst_generic1; class_inst_generic1 = app_usbd_hid_generic_class_inst_get(&ctap_hid_generic1); ret = app_usbd_class_append(class_inst_generic1); APP_ERROR_CHECK(ret);
the problem is that when i compile and load the app to PCA10056 dev board and connecting the board to the computer, in the device manager windows report below error about the device:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
can anyone give me a advice to solve the problem? there is any setting that i should to done when i want use 2 endpoint in my interface??
thanks
