This bug is known. It happens due to port timeouts. A patch that was fixing this issues was reverted recently as if failed on other devices.

Can you test libusb-win32 filtre with some CPU i Think will resolve usb timeout

[bkerler]

Actually this shouldn't happen with the new version, can you confirm ? If it does persist, did you try a different usb port / hub ?

1. Remove the USB from the phone before running every command
2. Run the command
3. Connect the USB to the phone by pressing vol+
4. Repeat

This fixes my problem: struct.error: unpack requires a buffer of 12 bytes

@bkerler Please use logging.FileHandler(logfilename, encoding='utf-8'). Windows gives encoding error without encoding parameter in FileHandler.

@bkerler Thank you for creating this awesome tool 🥰
