   @acassis - I only have sama5 boards and not sure if my eval boards are still usable! My thinking was that since the USB memory stick works 100% reliably and I can plug/unplug many times without issue it was unlikely to be the SAMA5 usb code - but it is possible. I think one is ohci and the other ehci so i will investigate further. After all, I did find an issue with the SAMA5 device driver so further issues are I guess rather likely.
   
   I did trace the connect, enumeration, and detach events and they superficially seemed to make sense. the keyboard actually works the first time, and it "feels" perhaps like a big chunk of memory is not being released.
   
   What I've not got a good handle on is debugging full blown crashes as the screenful's of register dumps seem rather pointless!
