This is fairly straightforward but, screenshot please!

I noticed that I wrote Close on the button 😄
I'll change it to Cancel, as it should be.

Please setup and run clang-format (Which can be installed by installing LLVM) as documented here

Once you pass linter I see no reason to keep this PR waiting

Actually I was just about to mention, forgot whole day, including @BhaaLseN also raised this today, if that button should say "Close" rather than "Cancel". It's been 5 months since I created the bug ticket and I'm not sure I really meant "Cancel", if I did then I forgot the thought process for that specific reason.

"Cancel" seems good to me, as the user cancels the addition of a new USB device. "Close" does not necessarily imply that.
But that's just my two cents.

Yes that's indeed correct in a way, I was just about to say, it may not be that of a big deal ofcourse, just raising the consistency thing.

However here's a stronger point after I did more thinking, "Cancel" would have to actually remove any of those devices from the whitelist .. (which isn't visible on this dialog, this list is showing all the available ones to select - @BhaaLseN) .. that were added while the dialog was open, IMHO.

I like how it is now.
