I've got the crossworks compiler installed and I can compile my code, however, when I select "AVR-ISP MKII" from the programmer list the IDE hangs for about 5 seconds and then closes.

How do I enable support for the programmer? is there a driver I need to install or is there another step I need to do?

  Do you have any other things plugged into the USB (other than mouse, keyboard)? If so you could you try unplugging them and retry the connection.

  It's on my macbook Pro, nothing plugged into the USB ports at all.

  Worth a try - this has fixed other MacOS problem reports. Not sure what to suggest now :-<

  I'm wondering if I need a driver of some kind.

  When I look at DMESG I see this -

  "

  USBF: 27635.596 AppleUSBOHCI[0x7031000]::Found a transaction which hasn't moved in 5 seconds on bus 0x6, timing out! (Addr: 5, EP: 0)

  USBF: 27635.919 IOUSBCompositeDriver[0x7419300](IOUSBDevice) GetFullConfigDescriptor(0) returned NULL

  USBF: 27635.919 IOUSBCompositeDriver[0x7419300](IOUSBDevice) GetFullConfigDescriptor(0) returned NULL

  "

  I'll keep tinkering.
