Devcon Failed Windows 10

Device Manager

DevCon is not redistributable. It is provided for use as a debugging and development tool.
Examples:

List all known PCI devices on the computer pc64.

Devcon.exe failed. This has worked fine in Windows XP. Am I forgetting something obvious? Also, is it possible to get some more information from devcon.exe of why it failed? I've also tried to install from 'device manager', the response is: The system cannot find the file specified. Here to, it would be nice to know which file it cannot find. DevCon disables the device even if the device is already disabled. Before and after disabling a device, use the DevCon Status operation to verify the device status. Before using an ID pattern to disable a device, determine which devices will be affected. To do so, use the pattern in a display command, such as devcon status USB. or devcon hwids. On my current Windows 10 test machine devcon with admin rights fails with an incredibly informative error: devcon install mytestl.inf mytest setupapi.dev.log does not get touched.

devcon -m:pc64 find pci*

Install a new instance of the Microsoft loopback adaptor and restart if required. This creates a new root-enumerated device node with which you can install a 'virtual device,' such as the loopback adaptor.

devcon -r install %WINDIR%InfNetloop.inf *MSLOOP

List all known setup classes. Displays both the short name and the descriptive name.

devcon classes

Lists files that are associated with each device in the ports setup class.

devcon driverfiles =ports

Disable all devices that have a hardware ID that ends in 'MSLOOP' (including '*MSLOOP').

devcon disable *MSLOOP

List all compatible drivers for the device ROOTPCI_HALPNP0A03. This can be used to determine why an integral device information (.inf) file was chosen, instead of a third-party .inf file.

devcon drivernodes @ROOTPCI_HALPNP0A03

Enable all devices that have a hardware ID of '*MSLOOP'. The single quotation mark indicates that the hardware ID must be taken literally (in other words, the asterisk ['*'] actually is an asterisk; it is not a wildcard character).

devcon enable '*MSLOOP

List device instances of all devices that are present on the local computer.

devcon find *

List all known peripheral component interconnect (PCI) devices that are on the local computer (this command assumes that a device is PCI if it has a hardware ID that is prefixed by 'PCI').

/uncharted-4-for-pc-download.html. devcon find pci*

List devices that are a member of the ports setup class and that contain 'PNP' in their hardware ID.

devcon find =ports *pnp*

List devices that are present that are a member of the ports setup class and that are in the 'root' branch of the enum tree (the instance ID is prefixed by 'root'). Note that you should not make any programmatic assumption about how an instance ID is formatted. To determine root devices, you can look at device status bits. This feature is included in DevCon to aid in debugging.

devcon find =ports @root*

List 'nonpresent' devices and devices that are present for the ports class. This includes devices that have been removed, devices that have been moved from one slot to another and, in some cases, devices that have been enumerated differently due to a BIOS change.

devcon findall =ports

Devcon Failed Windows 10 Wilcom

List all devices that are present for each class named (in this case, USB and 1394).

devcon listclass usb 1394

Remove all USB devices. Devices that are removed are listed with their removal status.

devcon remove @usb*

Rescan for new Plug and Play devices.

devcon rescan

List the resources that are used by all devices in the ports setup class.

devcon resources =ports

Restart the loopback adaptor ROOT*MSLOOP0000. The single quotation mark in the command indicates that the instance ID must be taken literally.

devcon restart =net @'ROOT*MSLOOP0000

Devcon Disable Failed Windows 10

List all hardware IDs of mouse class devices on the system.

devcon hwids=mouse

Assign the hardware ID, beep, to the legacy beep device.

devcon sethwid @ROOTLEGACY_BEEP0000 := beep

List the status of each device present that has an instance ID that begins with 'pci'.

devcon status @pci*

List the status of an Advanced Configuration and Power Interface (ACPI)-enumerated serial port.

devcon status @ACPIPNP05011

List the status of all COM ports.

devcon status *PNP05*

Errorlevels returned by DevCon.exe:
0 = success.
1 - restart is required.
2 = failure.
3 = syntax error.

Ok.. by checking the logfile: %windir%infsetupapi.dev.log I found that the
installer didn't find the WDFCoInstaller01009.dll, because I had added the

WDFCoInstaller01009_chk.dll(why doesn't it want the checked one when I

compile the code in a checked environment?).

So now I'm able to install the WDK drivers.. then over to my real problem,
my PCIe driver wont install(works on XP, thought it was relatet to not beeing
able to install the WDK example drivers on W7). From the logfile I get:

Why wont Windows select my driver even though my .inf file specifies that it
handles PCIe devices with vendor-ID 10EE?
