Hello Hakon,
I am making a USB HID, with 2 OUT reports in my descriptor.
I use the .int_out_ready
interrupt with some success to get my out report from a PC.
(CONFIG_USB_HID_REPORTS not set)
however,with a
hid_int_ep_read(hdev,data_from_pc,64,&ret_bytes);
the USB frames for out reports bigger than 16 bytes get sliced in chuncks of 16 bytes (4 .int_out_ready interrupts of 16 bytes each, for a 57 bytes out report).
My descriptor has already been used in another product with no problem.
I have tried what you describe, but I don't even get the
.set_report interrupt.
when I send the out report from the PC
which is worse in a sense.
I come here because doing what's described here does not help me.
And the CONFIG_USB_HID_REPORTS=2 does not make any sense for me.
I have no problem with the IN reports.
I use hidapi on the PC. And the
Here is the current state of my code (in report code not shown ).

0xC0 /* END_COLLECTION */when I was using the .int_out_ready
received ID= 129 reports were sliced by chunks of 16 bytes, I have changed the report so that both 128 and 129 reports can accept 36 bytes.
I have paid attention to uninstall the usb hid drivers in the PC
But that would not be enough.
