USB Device Tree Viewer 3.7.7​

February 13, 2022

• Workaround: Some ASMedia host controllers fail to deliver their root-hub's symlink by means of IOCTL_USB_GET_ROOT_HUB_NAME. Same problem when requesting the symlink of a standard hub (IOCTL_USB_GET_NODE_CONNECTION_NAME). Both calls may fail with ERROR_NOT_SUPPORTED when the ASMedia drivers asmtxhci.sys and asmthub3.sys are used. Both cases are resolved now by devices' parent-child relation.
• New: For /R and /X a 'magic' file name of "stdout" makes it write the text- or XML-report to stdout instead of an actual file. If not redirected it attaches to parent process' console or creates a new one.

USB Device Tree Viewer 3.7.8​

March 30, 2022

• Bugfix: V3.7.7 did no show a Window when started under XP thru the Windows Explorer (because it passes stdin/out handles, so UsbTreeView thinks it shall silently write a report to stdout)
• Bugfix: V3.7.7 crashed when a hub did not deliver its USB_HUB_INFORMATION

USB Device Tree Viewer 3.8.0​

V3.8.0

• New: Context menu item "Regedit..." to open certain device specific registry keys in the Windows Registry Editor
• Rewind: Reporting a USB version of 2.0 is no more blamed as an error if the device does not deliver an "other_speed" device_qualifier descriptor because the document

  says:
  "Full speed and low speed only devices designed to this specification should also use version number 2.0"
  even main USB 2.0 spec says in 9.2.6.6:
  "Devices that are high-speed capable must set the version number in the bcdUSB field of their descriptors to 0200H. This indicates that such devices support the other_speed requests defined by USB 2.0.". But Full Speed devices do not support the other_speed requests since the have no other speed...
