[Issues with Flirc + Any remote]

Had similar issue, downgrading the firmware worked for me:

I still have to program each key twice, but at least there are no conflicts now, and I'm able to actually use it. 

[Headaches with FW 3.6? Anyone else having problems?]

Here's the method that worked for me: http://forum.flirc.tv/index.php?/topic/1573-duplicate-key-ids-on-buttons/&do=findComment&comment=11796

[Duplicate Key IDs on buttons]

this forum is extrememly supportive... 

I ran into the same problem with the brand new flirc fw v3.6. 

I was able to find a way to downgrade the firmware. Luckily, GUI apps have specific fw versions bundled. 

So the approach is as follows 

- Download previous GUI version here: http://downloads.flirc.tv/release/gui/

- Connect flirc, don't run the GUI yet

- In terminal/console, go to flirc GUI folder (on MacOS - cd /Applications/Flirc.app/Contents/Resources)

- On MacOS I had to copy a lib: 

cp libusb-1.0.0.dylib /usr/local/lib

- Run

flirc_util dfu

- Now start the flirc app. It will download the firmware and install it to the thing.

I had to try several versions. 1.2.8 finally worked with me.
