UsbTreeView V2.6.1.0 - Shows the USB Device Tree
Freeware by Uwe Sieber - www.uwe-sieber.de
Works under Windows 2000, XP and higher
Usage:
UsbTreeView [/R:filename] [/L:logfile]
/R:filename write (silently) a report to filename
/L:logfile write a logfile for debugging in case of crash or hang (causes massive slow down)
UsbTreeView is based upon the USBView sample from the Windows Driver Kit for Server 2003.
Improvements:
- better icons in the treeview
- refresh on device change performed asynchronously, selected item stays selected
- shows additional information gathered from the Windows device management
- shows drive letters/mountpoints and COM ports
- can perform safe removal, device restart and port restart
- custom font and color for the right pane
- toolbar with jump-lists for easily finding devices in complex trees

If in the Registry under HKLM\SYSTEM\CurrentControlSet\Control\UsbFlags\VVVVPPPPRRRR there is a
osvc value != 0 then UsbTreeView reads it anyway because Windows already read it successfully.
VVVVPPPPRRRR is a 12 digit hex value containing idVendor, idProduct and bcdDevice from the USB Device Descriptor
ToDo:
- USB Video Class H.264 decoding
- Maybe Unicode support
About Unknown Descriptors
There are two reasons why decriptors cannot be decoded and therefore
shown as " Unknown " :
- decoding is not implemented
- the device's InterfaceClass is 0xFF (vendor specific), so class specific
descriptors cannot be decoded since their class is unknown
So, if you have an unknown descriptor and the interface class is not 0xFF
then please let me know, maybe I find the right specification document
and can add the decoding for it.
HID descriptors usually cannot be read. Probably this is because they
must be requested from the interface rather than the device but the
IOCTL_USB_GET_DESCRIPTOR_FROM_NODE_CONNECTION call doesn't offer the
choice. The parameters are ignored and filled by the USB stack:
" the USB stack ignores the value of bmRequest and inserts a value of 0x80
which indicates standard USB device request " .
https://msdn.microsoft.com/en-us/library/windows/hardware/ff539272%28v=vs.85%29.aspx
For most devices the result is an ERROR_GEN_FAILURE or ERROR_INVALID_PARAMETER.
But some devices return the HID descriptor anyway.
About " Safe Removal " and " Restart "
On Safe Removal UsbTreeView first calls the configuration management call
CM_Query_And_Remove_SubTree. On success the device has the problem code
21 which is CM_PROB_WILL_BE_REMOVED. A code 21 device can be reactivated
by performing a DIF_PROPERTYCHANGE class installer call. This is what
UsbTreeView does if you select " Restart device " .
But CM_Query_And_Remove_SubTree needs admin previleges, otherwise it fails
with CR_ACCESS_DENIED. In this case CM_Request_Device_Eject is called
which works without admin previleges but leads to problem code 47 which
is CM_PROB_HELD_FOR_EJECT. Such a device cannot be reactivated alone.
A reactivation is possible by restarting the port or the whole hub it is
attached to. But the latter of course restarts all devices attached to
the hub.
In all cases UsbTreeView just performs the system call and shows a
message-box if Windows returns an error. But Windows does not always
return an error, even there was one, so sometimes nothing happens at all.
About " Restart Port "
This calls IOCTL_USB_HUB_CYCLE_PORT which simulates a disconnect and
reconnect of the attached device.
It is available under XP but usually only for hubs which run with the
Microsoft standard driver. 3rd party drivers usually return
ERROR_UNKNOWN_FUNCTION.
Under Vista and Windows 7 it is no more supported by the Windows standard
drivers, it always fails with ERROR_NOT_SUPPORTED.
Since Windows 8 it works again but in contrast to XP admin previleges
are required. Without admin previleges it fails as under Vista and Win7
with ERROR_NOT_SUPPORTED.
About the Debug-Port
In Microsoft's USBView sample there is a list of USB host controllers
and their debug port. I've put the table into UsbTreeView, it shows
then in the properties of the host controller a line like so:
DebugPort (from List): 1
Windows 8 has extended USB information, it reports for each port if it
is debug capable and this works indeed (seen on a i945G Chipset with ICH7).
USB Mouses
If an USB mouse is moved while the tool requests its USB properties there
is usually an error because the mouse just has more important things to
do than answering descriptor requests. UsbTreeView tries then for some
seconds to get this information.
You might see the yellow question mark at the mouse's tree node for a
moment which disappears as soon as you stop moving the mouse.
This retry mechanism is done for all type of devices but usually its a
mouse where it helps.
Information shown in the tree-view
UsbTreeView is optimized for speed, therefore USB descriptors are not
gathered before a device is selected in the tree-view. So, information
which come from USB descriptors cannot be shown in the tree-view, it
all comes from the Windows device manager.
This is also why creating a full report takes a moment.
