avrdude: usbdev_open(): did not find any USB device "usb" bug

It worked, selecting "Arduino as ISP" an toggling back and forth a couple of times got it working.

I managed to upload "Blink", and even though it reports:

avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85

it is working as it should.

Thanks!
