It seems like the DFU driver was not installed correctly.
Did you download and install qFlipper properly (using the installer from the download page)?
If not, please do so. If you have used the installer, please do the following:
- Switch your flipper to DFU mode as described here.
- Connect it to your computer.
- Go to device manager and see if the following entry is present (as shown in the pictures below).
- In case you do not see it, or you see “Unknown device” instead, then it’s the driver issue.
- Please report back for further instructions (which will be dependednt on your answer).
