Windows 7 & Vista Support

Windows7/Vista and SourceUSB

All SourceUSB product features are supported under Windows Vista x86 since the 2.1 release. Starting with the 3.0 release, Windows Vista x64 is also supported. Beginning with the 3.2 release, Windows 7 - x86 and x64 support was added. Miniport-Usbport logging is currently only available on Windows 7/x86, Vista/x86, XP/x86, and Server 2003/x86 platforms.

USB Features in Windows Vista

Getting SourceUSB to support Windows Vista required considerable development for our analyzer driver. As our driver's logging capabilities have been enhanced to cover lower level interfaces, our driver has also become more sensitive to differences between Windows platforms. This increases test time and adds complexity.

Some of the Vista features which SourceUSB supports include:

• 3 new URBs:
  

  URB_FUNCTION_SET_PIPE_IO_POLICY
  URB_FUNCTION_GET_PIPE_IO_POLICY
  URB_FUNCTION_CONTROL_TRANSFER_EX
  (Amongst these, URB_FUNCTION_CONTROL_TRANSFER_EX
  will become a common sight in most traces.)

• 8 new USB Internal Ioctls:
  

  IOCTL_INTERNAL_USB_RECORD_FAILURE
  IOCTL_INTERNAL_USB_GET_DEVICE_HANDLE_EX
  IOCTL_INTERNAL_USB_GET_TT_DEVICE_HANDLE
  IOCTL_INTERNAL_USB_GET_TOPOLOGY_ADDRESS
  IOCTL_INTERNAL_USB_NOTIFY_IDLE_READY
  IOCTL_INTERNAL_USB_REQ_GLOBAL_SUSPEND
  IOCTL_INTERNAL_USB_REQ_GLOBAL_RESUME
  IOCTL_INTERNAL_USB_GET_DEVICE_CONFIG_INFO

• 2 new Hub Ioctls:
  

  IOCTL_USB_RESET_HUB
  IOCTL_USB_GET_HUB_CAPABILITIES

• 15 new Hub-Bus Interface functions (Version 6):
