Trying to bring a adafruit Trinket up on my RPI 3. Debian Jessie.
Using Arduino IDE 1.8.5.
Set Board, Programmer and ports according to Adafruit setup instructions.
When I try to load Blink...properly modified....I get the following errors.
avrdude: Warning: cannot open USB device: Permission denied
avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
Spent a morning on web...cannot overcome this!
I have tried everything I could find on the web...including quick fixés to the device and updates in /etc/udev...
No avail....
Any ideas? What am I missing?
Thank you.

While I can say I resolved it....I did somehow get it to work by adding my username to the dialout group that owns the /dev/ttyAMA0 usb.
So far so good!

Cool. I've got the same problem here. Permissions on the /dev/ttyAMA0 usb. Sounds like Linux. Is it? I'm on Winners 7. Can anyone out there in Windows-land tell me what has to be done for an equivalent setting in Windows 7? Thanks.
