To clarify: Issuing VIDs, and logo licensing & compliance testing are entirely distinct things. Every USB device must have a unique PID/VID combination, used to identify a device and load correct drivers. In order to produce your own device, you must have a VID of your own (in which case you manage PID allocation), or get a PID from someone else - a practice USB-IF frowns upon outside certain strictly defined circumstances. Obtaining a VID without USB-IF membership costs a one off fee of $5000. Having a VID doesn't entitle you to use the USB logo. Independent of getting a VID, you can become a USB-IF logo licensee or member ($3500, or $4000/year respectively) and certify your devices, whereupon they can bear the USB logo. The HaD post, and my original post that it's based upon, is entirely about the issue of obtaining VIDs and PIDs for hobbyists; certification is a separate matter.
