[diselOrenburg]

Using STM32F103C8T6 board. Opened project into Keil, then build and flash via ST-Link. After connecting the board to USB get an "Unknown device" in USB devices list. Tested on two boards. With and without ov5642 connected. BOOT1 jumper returned from boot to normal position. Other project is uploading and works.
