I cannot seem to make my new particle core connect to my computer. dfu-util never sees it, and neither does the particle cli.

While in dfu-mode (blinking yellow):

```auto
$ dfu-util -l
dfu-util 0.9

And while blinking blue:

This is a particle core, and I have worked with these before, but not this particular one. I’ve done a factory reset and tried both of these steps again. I do wonder if this has something to do with having to re-install node, and the particle cli. I had quite a bit of trouble getting both of those to work before I even got to this point.

This does not match up with a Core. Are you using a Core or Photon?

Also, is the device in DFU mode?

Can you also try `sudo dfu-util -l` and see if the results changes?

I switched USB cables, and it works now. Gah! (Sorry!)
