The arrow of time

Some of the new features are:

  - Full support for Split transactions, which means you can use your full 
speed USB audio on a high speed USB HUB.
  - Full support for HS ISOC transactions, which makes writing drivers for 
various HS webcams possible, for example
  - Full support for USB on embedded platforms, mostly cache flushing and 
buffer invalidating stuff.
  - Safer parsing of USB descriptors.
  - Autodetect of annoying USB install disks.
  - Support for USB device side (and a handful of USB device side chips)
  - Support for USB transfers like I/O vectors, means more throughput and less 
interrupts.
  - New UGEN backend and libusb library, finally solves the "driver unloading" 
problem.
  - A new USB API.
  - Many USB drivers are now running Giant free.
  - Linux USB kernel compat layer.
