V 2.1.0 having issues with port not showing on some boards.
Re-installed the drivers but not joy. Board is the Sparkfun Tiny Programmer for a Attiny 85. Worked with previous versions but not with 2.1.0 any Help?
If so, it is normal and expected that this programmer does not produce a port. This is a pure USB device. It doesn't use a CDC serial port.
You can upload to the ATtiny85 chip using this programmer by selecting Tools > Programmer > USBtinyISP from the Arduino IDE menus and then selecting Sketch > Upload Using Programmer from the Arduino IDE menus.
I see SparkFun's tutorial says to use the "Upload" button. Unfortunately that is not supported in Arduino IDE 2.x so make sure to use Sketch > Upload Using Programmer instead.
