Assigning to me to cut the icon for you if that's OK.

Thanks! Assign it back to me when the assets are available.

I think the attached should do it.

For future reference to myself, this is from the PSD in:
Chrome ux specs and sources > Chrome Omnibox icons
Which is quite a bit dated now. No cut image folder provided (hence they are attached.)

(Note these were already in the PSD so they might be in the system already.)

This will be implemented in M-52. In M-51 USB device connections will be disallowed from background tabs.

rolfe@, do we need a vector icon as well? The Bluetooth tab indicator appears to be using one: https://codereview.chromium.org/1746333002

I've confirmed vector icons are used everywhere other than OS X. It would be great to get this before the M-51 branch point as I have the rest of the patch written and tested.

Material USB vector icon lives here:

I'm a little rusty on desktop assets so if this isn't what you were expecting let me know.

Patch out for review, looks like we'll make it for M-51.

Remove page visibility requirement for WebUSB.

Now that there is a tab indicator for WebUSB it can be used from a tab
that is not in the foreground.
