make erase not working

[input]

I follow this video : https://www.youtube.com/watch?v=qa2406iiSbI&t=177s
But at min 32:52 from the video I get an error with could not openport /dev/ttyUSB0 permission denied.
There are more warnings about file /home/vagrant/esp-idf but I can not paste that in here because I have no support to copy and paste.
I am working on a Toshiba laptop with Windows 8.
Maby someone knows what is going on or maby someone have a wiki how to set up the ESP32.

Thanks

Add yourself to the "dialout" group and re-login.

Thanks. It works with sudo but when connectig to baud rate 460800 I get an error failed to erase flash only got 0 byte status response.
I have this one: http://www.raspberrypiwiki.com/index.php/ESP32-DevKit

Any ideas how to solve this.

It is flashed now while I tried again. I think my usb cabel is not working correct.
Now I have some problems with make deploy.

I bought a new micro usb cabel but with make deploy I get an error "Failed to set SPI params ,only got 1 byte status response."

Any ideas.

I tried again with make deploy and now it's working.
