<H3>SUMMARY</H3>
|
|
This document accompanies the "DevCon" tool which is a text-mode device
|
|
console. The instructions herein apply to the Windows XP operating
|
|
system. DevCon has been designed for use on Windows 2000 and Windows XP. It will
|
|
not work on Windows 95, Windows 98 or Windows ME.<p>The "DevCon" tool described in this article is a command line
|
|
utility that acts as an alternative to Device Manager. It allows individual
|
|
devices or groups of devices to be enabled, disabled, restarted, updated, removed and queried. Devcon provides information that is relevant to the developer and thus not
|
|
available in Device Manager.<p>DevCon may not be redistributed, but
|
|
is available as a debugging and development tool.</FONT> <font face="Verdana" size="2">The
|
|
source code for Devcon can be found at src\setup\devcon along with
|
|
documentation and may be freely modified for private use.
|
|
|
|
<H3>USING DEVCON</H3>
|
|
|
|
<p>Devcon can be found along with this documentation at tools\devcon. Devcon has
|
|
built in help that is displayed by typing "devcon help". Examples on
|
|
how to use devcon are described here.<p>Devcon accepts optional switches (-r for
|
|
reboot, -m to specify remote machine), a command and arguments related to that
|
|
command. Example DevCon commands are:<p><b>devcon find pci\*</b><p>Find and list
|
|
all known PCI devices on the local machine (assuming that a device is PCI if it has
|
|
a hardware ID that is prefixed by "PCI\").<p><b>devcon -m:\\foobar
|
|
find pci\*</b><p>Find and list all known PCI devices on the machine "foobar" (-m
|
|
allows target machine to be specified. IPC access to machine is required).<p><b>devcon
|
|
classes</b><p>List all known setup classes. The output contains the short
|
|
non-localized name (e.g. "USB") and the descriptive name (e.g.
|
|
"Universal Serial Bus controllers").<p><b>devcon listclass usb 1394</b><p>List
|
|
all present devices for each class named (in this case USB and 1394).<p><b>devcon find =ports *pnp*</b><p>List
|
|
present devices that are a member of the "ports" setup class and
|
|
contain "PNP" in their hardware ID.<p><b>devcon find =ports @root\*</b><p>List
|
|
present devices that are a member of the "ports" setup class and live
|
|
in the "root" branch of the enum tree (i.e., the instance ID is
|
|
prefixed by "root\"). Note that programmatically, no assumption should
|
|
be made about how an instance ID is formatted, and root devices can be
|
|
determined by checking device status bits. However this feature has been
|
|
provided in devcon to aid in debugging.<p><b>devcon findall =ports</b><p>Lists
|
|
non-present devices along with present devices for the ports class. This will
|
|
include devices that have been removed, devices that have been moved from one
|
|
slot to another, or, in some cases, devices that have been enumerated
|
|
differently due to a BIOS change.<p><b>devcon status @pci\*</b><p>Lists the
|
|
status of each present device who's instance ID begins with "pci\".<p><b>devcon status @ACPI\PNP0501\1</b><p>Lists the status of
|
|
a specific device instance, in this case an ACPI enumerated serial port.<p><b>devcon resources =ports</b><p>Lists the resources used by
|
|
all devices in the ports setup class.<p><b>devcon driverfiles =ports</b><p>Lists
|
|
files that are associated with each device in the ports setup class.<p><b>devcon
|
|
stack =ports</b><p>Lists the expected driver stack for the device, including
|
|
device and class upper/lower filters as well as the controlling service.<p><b>devcon drivernodes
|
|
@ROOT\PCI_HAL\PNP0A03</b><p>Lists all compatible drivers for the device
|
|
"ROOT\PCI_HAL\PNP0A03". This can be used to determine why an in-box INF was
|
|
chosen in preference to a third party INF.<p><b>devcon remove @usb\*</b><p>Remove all USB
|
|
devices. Devices removed will be listed along with removal status.<p><b>devcon
|
|
rescan</b><p>Rescan for new Plug&Play devices.<p><b>devcon update mydev.inf
|
|
*pnp0501</b><p>Update all devices that match (exactly) the hardware ID *pnp0501
|
|
to use the best driver in mydev.inf associated with the hardware ID *pnp0501.
|
|
Note that this will force all devices to use the driver in mydev.inf even if
|
|
there is a better match already on the system. This is useful for installing
|
|
new versions of drivers during development prior to obtaining a signature. It only
|
|
affects
|
|
the devices that match the specified hardware ID and not child devices. If the
|
|
specified INF is unsigned, Windows may display UI appear confirming that the driver should be
|
|
installed. If a reboot is required, it will be reported and devcon will return
|
|
with errorlevel of 1. Specifying "-r" will cause a reboot to occur
|
|
automatically if one is required.<p><b>devcon -r install %windir%\inf\netloop.inf
|
|
*MSLOOP</b><p>Install a new instance of the Microsoft loopback adaptor. Install
|
|
will allow a "virtual device" such as the loopback adaptor to be
|
|
installed by creating a new root-enumerated device node. Reboot the machine
|
|
silently if a reboot is required.<p><b>devcon disable *MSLOOP</b><p>Disable all
|
|
devices who's hardware ID ends with "MSLOOP" (including *MSLOOP).<p><b>devcon
|
|
enable '*MSLOOP</b><p>Enable all devices who's hardware ID <i>is</i> "*MSLOOP".
|
|
The single quote indicates that the hardware ID must be taken literally.<p><b>devcon
|
|
restart =net @'ROOT\*MSLOOP\0000</b><p>Restart the loopback adaptor "ROOT\*MSLOOP\0000".
|
|
The single quote indicates that the instance ID must be taken literally.<h4>Notes</h4>
|
|
<ul>
|
|
<li>Devcon will return an errorlevel for use in scripts. 0 indicates success.
|
|
1 indicates that a reboot is required. 2 indicates a failure. 3 indicates a
|
|
syntax error.</li>
|
|
<li>If "-r" is specified and a reboot is required, the reboot will
|
|
occur without warning once all devices have been processed.</li>
|
|
<li>If "-m:\\machine" is specified and the command will not work for
|
|
a remote machine, an error will be reported.</li>
|
|
<li>Devcon allows wildcards in instance ID's for interactive convenience. No
|
|
assumption should be made about the format of an instance ID from machine to
|
|
machine and from OS version to OS version.</li>
|
|
