I'm just beginning my adventures with Arduino, and trying to get Arduino IDE to recognize my Trinket Pro. Page 27 of the "Introducing pro-Trinket" PDF
explains to select the board Tools>Board>Pro Trinket 3V. My problem is that none of the Trinkets are an option on the menu.
BTW, I have installed the required USBtinyISP driver. I've tried other board selections and the error is that the board is not recognized.
