I was doing some tests with an ATtiny85 Digispark module using Arduino IDE on my Windows PC. I was testing some stuff with the DigiKeyboard library from Digistump.

Everything was going fine until suddenly the Digispark stopped working and wasn't able to upload code through the module anymore. Now when I plug it in my PC, the only thing that the module does is turn on the green led; besides, Windows doesn’t recognize the module when I plug it in anymore and doesn’t even appear in Device Manager as an unknown device or something.

I reinstalled the drivers but nothing changed. I also tried to reinstall Micronucleous into the ATtiny85 using Zadig, but wasn’t able to do it because Windows doesn’t recognize the module when I plug it in, so Zadig won't see it either.

Since I’m not very familiar with electronics, I’m not sure if there is any way to fix this or if it’s due to some physical damage, so any help or direction with how to deal with this would be really appreciated.

  • are you certain that windows is not recognizing anything at all? – jsotola Jul 2 '20 at 7:11
  • Yes. I double checked Device Manager and I couldn't see it there; besides, Windows doesn't play this sound that you hear when a USB device gets connected. – Vile Jul 2 '20 at 8:49
  • afaik digispark doesn't have USB chip and the Atiny doesn't have native USB. you must program it over ISP. and again afaik, software USB bootloader can be used. a new Digispark should have it. – Juraj Jul 2 '20 at 9:47

    @Juraj I'm not sure of what you mean, from what I know, the Digispark was made to be able to program the attiny85 via USB. I was able to program this exact Digispark in the past, but in some moment something went wrong and wasn't able to do it anymore – Vile Jul 2 '20 at 19:08

    @vile Do you have any updates? I literally just ran into this issue today....I got various scripts loaded, worked fine, now today suddenly it stopped getting recognized ![enter image description here](i.stack.imgur.com/SzNpS.jpg) I tried everything so far, but it's not even showing up on the device manager. – Corfucinas Aug 3 '20 at 8:22
