ATTINY85 + Micronucleus, vcc + gnd does not work, also need to power pin2?

ATTINY85 + Micronucleus, vcc + gnd does not work, also need to power pin2?

ive got a cheap usb digispark type adapter for my attiny85's. I used the in system programmer to load micronuclus from my Arduino Mega, and now I can program no problem using the digispark usb adapter.

however, when I transfer the 85 to a breadboard it does not run my program. I used my volt meter I noticed pin 2 from the usb adapter was also powered. so I jumpered vcc to pin 2 and it starts working on my breadboard.

does anyone know if this is somthing related to the 85, or the bootloader?

seems silly to me. took for ever to figure out how to get it to work on my breadboard.

anyone have any ideas whats going on?

Thanks!

Which package are you using? SOIC8 or QFN20? How about a picture of your setup and some simple test code. Pin 2 should not need any input. It has an internal pullup so it shouldn't need to be driven high. Are you sure you are counting the pin numbers correctly?
