* - Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley)
* - Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code
* - Removed DESCRIPTOR_COMPARATOR() macro - comparators should now use regular function definitions to clarify user code
+ * - USB_IsConnected is now cleared before the USB_Disconnect() event is fired in response to VBUS being removed
