From the output, it seems like the device fell off the USB bus right as it went into RX mode. Bad USB cable perhaps?

[Ross966]

Thats fixed it! I tried two differnt USB cables before but of the same (and presumably low) spec. I tired a new USB cable and it works. Easy fix. Thanks you!

[martinling]

Great! Glad to have an easy one!
