Can't Upload Code To Blinks, it shows up as "unknown device" in device manager

[DavidHalasz]

Hi Everyone!

When I tried to upload code to a Blink, the IDE gave me an error message saying: avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)

Then I checked device manager and the Blinks came up as unknown device

Can someone help me?

Many thanks,
David

Hi @DavidHalasz!

Welcome to the forum Looks like you are just missing the driver for the USBtiny. Try installing this one here. Once installed (and possibly restarted) it will no longer show up as an Unknown device. Then Arduino should happily use it as your programmer.

No programmer detected?

Check to make sure you have the correct driver installed , relaunch the Ardunio IDE and then you should be able to select USBTinyISP from the Tools > Programmer dropdown in Arduino.

Definitely follow up here, and I bet some others will chime in to help you along the way!
