Problems in firmware upgrade

The Openmv I own has the ARM STM32F427 but is with the firmware Openmv1 thus does not recognize the libs for the use of LEDs IR and WiFi in micropython in the update use the instructions of GitHub - openmv/openmv: OpenMV Camera Module site wiki / Linux-Installation and always gives the following error:

Traceback (most recent call last):
File “./”, line 304, in fwupdate_task
pydfu.init ()
File “/home/alinsson/Downloads/openmv-1.1/usr/”, line 80, in init
raise ValueError (‘No DFU device found’)
ValueError: In DFU device found

The module works seamlessly with examples github using only camera but can not upgrade for OpenMV2, you have any suggestions? Thank you.
ps: sorry English kkkk

Could you connect the camera and paste the output of lsusb ?

I’m guessing you may have a very old firmware before the VID:PID changed, if so, use the new IDE to update the camera, the latest on in the repo should allow you to update the cam, if that doesn’t work, try uploading the firmware manually:
