STM32F207 - Error "Device not found in database" but present

[User3546]

With qstlink2, after clicking on 'Connect', i get:
32 Device descriptions loaded. Searching Device... ST Link V2 / Nucleo found! Fetching version... Changing mode to SWD... Fetching mode... Mode: Debug Fetching status... Status: Unknown Fetching MCU Info... Device not found in database! Disconnecting... Disconnected.

The device is not found in the database. But i work on a STM32F207, and in the /usr/share/qstlink2/devices.xml, this device is present:
<device type="STM32F2xx" coretype="CM3"> <core_id>0x2ba01477</core_id> <chip_id>0x411</chip_id> <flash_size_reg>0x1FFF7A22</flash_size_reg> <flash_int_reg>0x40023c00</flash_int_reg> <buffer_size>0x8000</buffer_size> <loader>loader_f2.bin</loader> </device>

In the terminal, i get more information:
user@user-VirtualBox:~$ qstlink2 Verbose level: 3 Version: 1.2.3 174 - Info: libpng warning: iCCP: known incorrect sRGB profile 188 - Info: Devices list loaded. 200 - Info: "32 Device descriptions loaded." 3975 - Info: "Searching Device..." 3975 - Info: Cannot open device 4003 - Info: "ST Link V2 / Nucleo found!" 4003 - Info: "Fetching version..." 4010 - Info: "Changing mode to SWD..." 4123 - Info: "Fetching mode..." 4138 - Info: "Mode: Debug" 4138 - Info: "Fetching status..." 4144 - Info: "Status: Unknown" 4144 - Info: "Fetching MCU Info..." 4150 - Info: CoreID: 2BA01477 4162 - Info: CM3/4 Searching at E0042000 4162 - Info: ChipID: 0x005 4162 - Error: Did not find chipID! 4162 - Info: "Device not found in database!" 4162 - Error: Device not found in database! 4162 - Info: "Disconnecting..." 4168 - Info: "Disconnected."

I remark that the chip_id does not correspond to the one in the devices.xml file. Should i change it? Is 0x411 an incorrect one?
