What voltages are supported? 5V? 3V3?

My boards are all 5v, have not tried 3.3v. Works on 5v with studio 7. I also bought the AVR programmer from Microchip, since my attiny1617 boards need the "one wire" programming method that this programmer doesn't support. Good luck!

What is the avrdude setup? i have been able to get it to work intermittently and very slowly with: avrdude -c avrisp2 -p com2 -p t13 -v -emyfile.hex

Im not sure about the 'speed' you expect but you have to make absolutely sure you use the same physical USB port once the drive is installed. Go look up Zadig USB driver installer. Also, I was not able to get that programmer to work properly until I used the 10 pin connector via an adapter into a 6 pin socket on my prototype board. https://www.amazon.com/Comimark-Convert-Standard-Adapter-AVRISP/dp/B07WZF6Z27/ref=sr_1_3?crid=3NTU71Z2RSE9J&dchild=1&keywords=10+pin+to+6+pin+adapter&qid=1606212565&sprefix=10+to+6+pin+adapter%2Caps%2C193&sr=8-3 the above made it possible to use Atmel Studio with the programmer (it sounds like you have a cable problem, as if the drivers were not properly installed, it would not work at all)
