I have a couple of trinkets (5V and 3.3V) and my projects work great on them. My next step was to try an build a trinket myself on a breadboard and have my simple USB project run on there. Here is what I have setup (see image below). Those wires which are connected to the ATtiny85 chip are connected to this cable (http://www.adafruit.com/products/954) with wire colors in the file comment. I have uploaded my hex file using the USBTiny programmer (http://www.adafruit.com/products/46) to program my ATtiny85 chip. (note bigger chip, ATtiny2313 is not used in this setup, but I have it on the board)
The issue: I have VUSB implemented in my program (like I do on the trinket, which works). However, when I connect the USB TTL cable to my computer, I do see the cable as a USB device
