Hello everyone,
I’m having a lot of difficulty getting the Tiny AVR Programmer, aka (PMG-11801) to work on my Ubuntu 18.04 laptop. I have read several forum posts from various places and tried a solution that looks like it out to work but it has not. Here’s what I’ve done.
mmachenry$ lsusb
...
Bus 001 Device 013: ID 1781:0c9f Multiple Vendors USBtiny
...
I note the 1781:0c9f
From various web pages it seems like I need an entry in /etc/udev/rules.d to allow permission to use this device. I added it and it looks like this
mmachenry$ cat /etc/udev/rules.d/99-USBtiny.rules
SUBSYSTEM==“usb”, ATTR{idVendor}==“1781”, ATTR{idProduct}==“0c9f”, GROUP=“adm”, MODE=“0666”
Also note that I’m in the proper group.
mmachenry$ groups
mmachenry adm dialout cdrom sudo dip plugdev docker lpadmin sambashare
I also ran these immediately after creating that rules file.
sudo service udev restart
sudo udevadm control --reload-rules
But when I run avrdude, I get permission denied.

avrdude done. Thank you.
However, I get much different, positive output when running the command with sudo.

avrdude done. Thank you.
Why is the permission for a regular user to access this device still denied? By the way this works on my friend’s Mac and another friend’s Windows machine so I know that the programmer and the ATTiny85 in it are function just fine and not damaged.
Thank you.
