I'm still not comfortable with the idea of a USB connector on an instrument panel clock.
Tell me when have any of you before seen a cable coming out of an instrument panel? What kind of entanglement mess is being set up here?
The only concession that I see normally done are the headsets that all pilots wear, and those jacks are usually placed at the far sides, if they're even in the instrument panel at all (usually they aren't).
This is the kind of clock with USB port you can get:
Are you absolutely sure you want to add more cables to an instrument panel? Headsets are one thing, USB cables invite so many more uses. Also, the replacement of a clock may or may not be obtrusive. Take the example I found below. The red arrow is off to the side, and right beside the jacks for the headsets. Probably no big deal. The blue arrow on the right side may also be a clock (but possibly a total fuel consumption counter). If that was replaced to put in a clock with a USB port, I think I'd have more concerns about that location.

I personally believe that people who become pilots are self-selected and trained to be pretty clever about these kinds of issues, so ultimately it will rarely be an problem that any pilot would allow to get dangerous. But doesn't it look like we're violating a principle of design, here? Name for me an aircraft instrument panel that normally has cables hanging off of it? Pictures, please? Setting aside the usual headphone cables, of course, what examples are there?
