I am trying to upload code the "blink" sketch to a new pro trinket with micro usb cable. I have added the URL as suggested in the preferences. I have then installed it under Board Manager. I have also went into tools and selected the 5v/16 MHz (usb). I keep getting this following error when I attempt to upload. avrdude: usbdev_open(): did not find any USB device "usb"
The programmer defaults to AVRISP mkII so I left it there and it gives me this error. I did tried the other programmers but they just give different error messages. I am not sure what else to try. Is it possible I have the wrong type of Micro USB cable??
Any help would be greatly appreciated.
