+```
+In this example we see that more than one part of the Pinecil is detected as a DFU interface and we need to specify which one we want to flash to. We want to the `Internal Flash` so in this case we can use `alt=0` to identify which interface to target. The command would then look like this:
+```
+dfu-util -D Pinecil_EN.dfu -a 0

 ### Windows
 
 For Windows there are two options, you can use dfu-util via command line as shown above.

You can still install on the old version, but you will have to specify which DFU interface to flash to. Running the command `dfu-util -l` will show you if there are several DFU devices detected.
