iozone test complete.
However, it doesn't show up on USBImager 1.04 (last Debian/Ubuntu .deb). I have formatted it with gpt and ext4, but still no luck. Apart from that it works fine. I was wondering what I can do to get this fixed?

I could 'dd' but I like your software so much, so this is almost not an option ;)
