Error could not find USBtiny device (0x178/0xc9f)

Post by bdodds »

I'm using the kit from here I got a few years ago.
Mac OS 10.14.6 on a MacBook Pro with AVRDUDE in the terminal.
The USBtinyISP was working just fine till today when I started getting the Error could not find USBtiny device (0x178/0xc9f)

The green light comes on and I can see the device listed in the system report for connected USB devices...

I have used it hundreds of times on this same laptop without issue. How would I test to see if the device is indeed still working?

No one has any ideas? Is anyone else using the USBTiny on MacOS 10.14.6 successfully?

Just signed up to say that I'm having exactly the same issue. Everything was working fine until a few days ago, now avrdude inexplicably can't find the USBtiny device, despite it being listed in connected USB devices. Currently using a Macbook Pro 13" 2019 on 10.14.6.

Okay, I solved it (at least for me). If you simply reinstall avrdude using Homebrew (then restart) it works. Perhaps a recent update broke something?

Hope this helps someone else!

I think I installed using Crosspack, can you provide a link about installing via Homebrew?

It's pretty simple. Follow the instructions here: https://brew.sh/

You'll need to copy the following into Terminal to install Homebrew:

Code: Select all

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then, once it's done, you'll need to enter:

Code: Select all

brew install avrdude
Restart your machine and you should be good!

protodome, you rock.

I installed Homebrew and then had it install Avrdude again and it works now!

I'm guessing in the 10.14.6 update broke it because another mac running 10.14.5 still works.

Thank you @protodome! It sure helped me. I had the exact same issue and reinstalling avrdude worked. It had been working just fine not long ago, but then I kept getting that error.
