To me, it made more sense to track which boards go together in a cluster; when reviewing a request to actually use a duplicate vid/pid, you want to know what board(s) it is aliasing. I also revamped the detection of non-USB boards so that a board .mk file that couldn't be parsed by the code here would raise a problem instead of just being skipped for the purposes of checking. There were some lines with comments on the end, and some variation in capitalization of the IDs. These are all normalized and a (sometimes unfriendly!) error printed when it's incorrect. Before this, here were some ways to trick the duplicate vid/pid checker: ``` USB_PID = 0XABCD USB_PID = 0xAbCd USB_PID = 0xABCD # harmless comment? ``` None of these things were ever done on purpose.
