Check your crystal, but I think it's more likely Gareth> a software problem. If you send me a pcap file (capture with Gareth> wireshark) I'll have a look at it. I am not talking about user software. I talk about the system software, when booting with Boot1==0 and Boot0 ==1, and I have not influence on the software. After enumeration, dfu-util did see the device, I did no further test for now.
