gato ~ # switch_to_portapack Hold down the HackRF's DFU button (the button closest to the antenna jack) then plug the HackRF into a USB port on your computer. After the HackRF is plugged in, you may release the DFU button. Press any key to continue or ^c to abort

This is what it looks like when I run the switch_to_portapack script. I really don't like this bit: unable to read DFU status can't detach Resetting USB to switch back to runtime mode error resetting after download

That said, both scripts seem to work flawlessly anyway. Is this normal or something we need to consider improving?

It's normal and something we need to improve. It's noise from dfu-util that doesn't actually impact the process. Also, the barfing of hundreds of "Writing XXXXXX bytes at 0xYYYYYYY" is something that will be silenced by default when my HackRF patch is accepted.

Would you perhaps like to silence the dfu-util output in the scripts? I can run some tests silencing stderr or everything and make it less ugly by just reading error codes possibly.

@ZeroChaos- Please do. I don't see any command line options for dfu-util to silence the noise, so it will no doubt require some dirty tricks.
