Hopped in my sled this morning to head to work and waited patiently for the USB stick to load my tunes. To my dismay, the screen said it was loading but then came back with the USB Error message. I'd been using this Kingston 16 gig stick for about a year now (since I bought it last February) and it worked fine. Took it out and plugged it back in again several times, but same result. Turned the vehicle off and waited a minute or two and turned it back on....same result. So, I bought a new USB stick (sony 16 gig) and loaded everything onto it....and it works like a charm. Not sure why the Mazda doesn't read the Kingston stick anymore, yet it opens fine on my computer. I did a search here for this issue and came back with vague results so I figured I'd post this message to help anyone else down the line.
