Accessibility bugs for the Web should be based upon the WCAG 2.0 (AA) standards. Usability bugs are issues that don't fit within the technical specifications, what user testing returns from people you use who have the disability and don't fall within the WCAG 2.0 standards. The same concepts used for people without disabilities also applies here.

Example:

if an graphic has no alt tag, then that is a accessibility issue. If there is a image button that has an alt tag which hides extra options like a hamburger. If the alt tag is not clear, then this is still an accessibility issue. If the same graphic button is clearly explained and the user doesn't know how to invoke the icon or understand the purpose of the button. Then this is a usability issue.

I am specifically picking on the Hamburger (three horizontal lines) as not many people are aware of them. I have even ask a few younger people in my organisation and they are not sure either.
