Hi,

I am sorry for the late reply.

[quote][/quote]

APP_USBD_HID_GENERIC_GLOBAL_DEF(m_app_hid_generic_in,1,hid_user_ev_handler,(NRF_DRV_USBD_EPIN2,NRF_DRV_USBD_EPOUT2),reps,1,0,APP_USBD_HID_SUBCLASS_NONE,APP_USBD_HID_PROTO_GENERIC);

Have you tried setting the buffers to align the size of your input and output report? Now you have set these to '1' and '0', but it seems that this should be set to 63, 0.

Could you share a project that is showing this issue?

Kind regards,

Håkon

Hi，

Thanks for your replay.

1、It has out section. Communicate between pc and device（52840）.

#define DEF_HID_DSC_NEXT() { \
0x05, 0x01, \
0x09, 0x00, \
0xa1, 0x01, \
0x15, 0x00, \
0x25, 0xff, \
0x19, 0x01, \
0x29, 0x08, \
0x95, 0x40, \
0x75, 0x08, \
0x81, 0x02, \
0x19, 0x01, \
0x29, 0x08, \
0x91, 0x02, \
0xc0 \
}
APP_USBD_HID_GENERIC_SUBCLASS_REPORT_DESC(hid_desc,DEF_HID_DSC_NEXT());
static const app_usbd_hid_subclass_desc_t * reps[] = {&hid_desc};

2、Independent enable HID or MSD.

Yes，i'm sure.

Thanks.

Hi,

How does your descriptor look for HID generic? Does it have an output section?

[quote user="etomatoes"]2、Independent enable HID or MSD.[/quote]

If you enable only HID, it works (both IN and OUT). If you only enable MSD, it works. Is that correct?

Kind regards,

Håkon

The following options work will：

1、hid change to:

APP_USBD_HID_GENERIC_GLOBAL_DEF(m_app_hid_generic_in,1,hid_user_ev_handler,(NRF_DRV_USBD_EPIN2),reps,1,0,APP_USBD_HID_SUBCLASS_NONE,APP_USBD_HID_PROTO_GENERIC);

it works will.

2、Independent enable HID or MSD.

it works will.
