Yes may be...But I already changed this line with the JPEG filter and I added a jpeg image on the root of the SD card (if the STM32 can't read in /DCIM/... subdirectory):USBH_MTP_GetObjectHandles(&hUSBHost, 0, PTP_OFC_EXIF_JPEG, 0xFFFFFFFF, &WavHandl...

Hi @Mohamed_AYED ,Following the documentation, the Canon supports PTP. (class 0x06)It is confirmed with the STM32 MTP example demo because it passes the comparison level. And also I captured some informations with USBtreeview when the camera is conne...
