I have been trying to install the MSVAD virtual audio sample drivers from the Windows DDK on Windows 7 64bits, without success.
I modified the sample INF to only support the "simple" driver. The ChkInf tool confirms that everything is OK with the INF file, I signed the package with a Test certificate. So far, so good.
The problem is: despite reading the documentation on the Microsoft website, I have no clue of how to actually install this driver. The problem is that it does not match a physical device, so I can't use the Device Manager to update the driver on an existing device.
Aside from that, the right-click on INF + Install method does not work as the INF lacks a DefaultInstall section (which is a requirement for signing drivers).
I would like to be able to install this driver from the command-line ideally, but if a specific program is required, I'll have to go that way.
Thanks in advance for any clue on how to solve this.
Well, I guess I hadn't searched far enough: http://social.msdn.microsoft.com/Forums/en-US/windowspro-audiodevelopment/thread/68ac63f3-7bb1-45b0-9677-957d7aa9f2d9

I want to install signed driver but unfortunately the .inf file does not contain the correct hardware IDs. (incompatible driver)
I can install the driver manually like described here:
Force installing incompatible .inf driver in Windows Server 2019 Core
Right Click Update Driver in Device Manager
"Browse my computer for computer software”
“Let me pick from a list of available drivers on my computer”
Select “Have Disk…” and point to the driver folder
Now I'm looking for a way to do the same from script or code.
What I've tried so far:
I've tried to install the driver with devcon install -r <inf file> <device id> without success (error without any log).
patching the inf file with hardware Ids would break the driver signature and this is therefore not a good solution
PnPUtil: This adds the driver to the driver store, but because it is not compatible, the driver is not installed
It would also help to have answers or comments to the following questions:
Where can i get more logs from devcon to see detailed error descriptions
Can I somehow sign the driver by my self after patching the inf file?
Any other Ideas what i could try?
I need to communicate with a simple custom device directly through USB. I have full specifications for communication protocol. Unfortunately, the device vendor did not provide WinUSB driver for the device.
According to
https://msdn.microsoft.com/en-us/library/ff540283.aspx#inf
I should be able to install WinUSB driver automatically on Windows 10 using the inf template.
But installation fails with:
The third-party INF does not contain digital signature information.
As I understand, it is looking for a signed .cat file. But in this case I have no any files to sign nor .cat file. I just want to install Windows own WinUSB driver for the device, and clearly Windows drivers should be signed by Microsoft.
How do I proceed to install the .inf file?
If you only care about supporting Windows 8.1 and later, and you have the ability to change the device's firmware, you might consider using Micrsoft OS 2.0 Descriptors. This will allow a Windows computer to recognize the device as a WinUSB device and automatically load the WinUSB driver.
Another option would be to use Zadig or the related library libwdi to install the driver for your device. I would only recommend this for small, temporary, or organization-internal installations since it is kind of a hack (it installs its own certificate into your Trusted Root Certification Authorities list).
You could also look into disabling driver signature enforcement on your computer if you want to use the unsigned INF file.
If none of those options are going to work for you, then you need to look into buying a code-signing certificate from a certificate authority and signing your driver. Code signing for Windows is an ever-evolving field but my article Practical Windows Code and Driver Signing attempts to document what you need to know.
I have been wanting to work with Vulkan, the new graphics API and have gotten it up and running with no problems on Windows 7. However I can't get Vulkan to work on linux. When I try running any of the LunarG samples, or even my own code, vkEnumeratePhysicalDevices always says that there are no physical devices. Here is my setup:
OS: Ubuntu 16.04 (LTS) [x64]
GPU: Nvidia Geforce GT 730 2GB GDDR5
Driver: NVIDIA Binary driver - version 364.19 from nvidia-364 (open source)
Vulkan SDK: LunarG v1.0.17.0 [ latest version]
I was wondering if maybe there's a file for my GPU that I need to set an environment variable for, but I really don't know. As I said before, this worked on Windows 7 perfectly, but I can't seem to get this to work this the above configuration. I am able to create an instance with the LunarG standard validation layer and the correct extensions, but vkEnumeratePhysicalDevices doesn't find any physical devices. It doesn't give an error, just says it can't find any physical devices. This has really got me stumped and I would really appreciate the help. Thanks!
Depending on your distribution you may have to install the nvidia-utils package. See this issue on my Vulkan repo for details.
If this isn't the case for you check the directories Karl mentioned and check if there is no other ICD (maybe one from Intel) that may cause troubles. If you're on an optimus system with dual GPU you may need to explicitly activate the NVIDIA GPU.
The 730 should work fine on Linux, at least judging from the Linux hardware reports I got on my database like this one.
You shouldn't have to set an environment variable if the driver installed properly.
One way to check for a proper installation is to look for the JSON file that identifies the driver. For example, an nvidia driver will place a file called nvidia_icd.json in /etc/vulkan/icd.d/. /usr/share/vulkan/icd.d/ is another standard, but less common location.
It may also be the case that your GPU does not support Vulkan. Be sure to check your GPU vendor's web pages to confirm support. You may want to download the driver straight from the vendor's site in order to get one that they say has Vulkan support.
And are you sure that using the "Additional Drivers" page is supposed to give you a Vulkan driver?
You can refer to the loader documentation in the docs section at https://vulkan.lunarg.com for more info.
I need to create an automated process in which a script detects the graphics card type on first boot, then installs the appropriate drivers, which will be included in the image, before performing the next steps. The target platform is Win XP Pro.
I came across some WMI code which can get hardware information but since it uses a PNPSignedDriver class I would presume that it requires drivers to be installed before it can detect the device.
I can't use devcon, as it isn't redistributable. Am I right in assuming that WMI cannot help me here, and if so what are my other options?
Thanks,
Bill.
WMI does seem to be the way to do this, as found here. I will confirm after testing.
EDIT - Not sure if this is possible, WMI can only get the name of the display adapter not the device ID of the card, and before the drivers are installed this is something generic like "Video Controller (VGA)". I will update this page if I find a way.
I am working on a program that requires to install a driver for Plug and Play. My issue is that the first time the device plugs into, by default, windows 7 32-bit automatically search online for drivers that better match to device. As i observe, it takes too long (15m) to correctly install the driver.
How can i turn off the automatic search on windows 7?
Thank you for any useful information.
Apparently you do this through GPO, as described here:
http://www.verboon.info/index.php/2010/12/windows-7-device-installation-without-administrative-rights/
Look for "Prevent Clients from searching for drivers on Windows Update" on this page.
Read up on applying GPO programatically and you should probably be able to get the job done. However, mind that you'd be changing the policy for the whole system, not just installation of this device.
If you install a driver package for your driver before you insert it, Windows will not search online.
If you really want to disable online serach on your machine - take a look here.
