Driver projects we haverecently delivered
Developing Drivers for Low Latency Virtual Reality Headsets
Our team designed and delivered two drivers and a data transmission protocol even before the client’s device was ready for release.
The drivers are WHQL certified and help the device operate with 3–10 ms of latency and ~11 Gbps data transmission speed. The client successfully released their product and received positive feedback on it.
Improving a Windows Audio Driver to Obtain a WHQL Release Signature
Apriorit helped a British audio technology company rework the Windows driver for their AI-powered product and successfully pass WHLK/WHQL testing.
IRIS has been satisfied with the quality of services provided by Apriorit experts and continues cooperating with us. Our experts are supporting and maintaining the Windows version of the app, improving its security and performance
Developing a Custom Driver Solution for Blocking USB Devices
We helped a client build a driver for managing USB ports on computers that blocks USB devices according to a set of rules, works with different versions of Windows and macOS, and is compatible with other enterprise software.
The driver created by the Apriorit team increased both the value of the client’s product and the client’s competitive advantage.
Developing a Windows File System Minifilter Driver
Apriorit built a system minifilter that showed opened files in the debug output, preventing unauthorized access to files and processes.
This solution allowed us to improve the security, flexibility, and performance of a target product.
Writing a Windows Driver in Rust
Our team has built a minifilter driver for access protection using Rust.
Choosing Rust for this project allowed us to minimize memory-related issues, prevent driver crashes, and improve the solution’s security without sacrificing performance.

FAQ
Can Apriorit develop a driver before the hardware is ready?
<p>Yes, when specifications and interfaces are sufficient. We build proofs of concept and use device emulation, including QEMU and custom simulators, to develop and test driver logic before physical hardware is available.</p>
Once hardware arrives, Apriorit experts validate and refine the driver against it. For example, in our <a href=/case-studies/726-driver-development-for-vr-headset>VR headset driver project</a>, we started development using emulated devices and later validated the solution on physical hardware.
Can you modernize or take over an undocumented legacy driver?
<p>Yes. We start with reviewing the driver’s source where it’s available and legally permitted. During the review, our experts analyze binary behavior to recover missing documentation and understand undocumented logic.</p>
After crash history investigation, we migrate the driver away from deprecated APIs and frameworks and modernize it for new Windows versions and hardware targets.
Can you port a Linux or macOS driver to Windows?
<p>Yes, though this is rarely a direct translation. At the beginning, our Linux experts analyze which parts of the existing logic can be reused. After that, our driver experts redesign the OS-specific layers such as APIs, build systems, and packaging and conduct tests to ensure they fit the Windows driver model.</p>
In our <a href=/case-studies/774-custom-driver-usb-blocking>USB Wi-Fi adapter case study</a>, this approach allowed us to bring an existing driver’s core functionality to Windows while rebuilding the components tied to the original OS.
Can Apriorit help with HLK testing and WHQL certification?
<p>Yes, we can prepare your Windows driver for <a href=/qa-blog/631-qa-whql-testing-microsoft-hardware-certification>WHQL certification</a>. Specifically, we’ll run HLK tests, troubleshoot failed test cases, fix driver issues, and prepare the driver package for submission.</p>
We combine technical depth with rigorous testing, helping clients release stable, compliant, and high-performance drivers efficiently.
How do you test Windows drivers?
Apriorit experts run driver tests across target Windows versions and updates, using both virtual and physical environments to cover a range of hardware configurations. Our testing scope includes functional, compatibility, stress, performance, and security testing. In addition, we check install, update, uninstall, and recovery scenarios, plus HLK testing when certification is part of the project.
How much does Windows driver development cost and how long does it take?
<p>There’s no universal timeline or price, since driver projects vary significantly in scope. The <a href=/dev-blog/driver-development-cost>cost and duration of a driver development project</a> depends on factors like:</p>
<ul class=apriorit-list-markers>
<li>Driver type</li>
<li>Hardware availability</li>
<li>Existing documentation</li>
<li>Target systems and architectures</li>
<li>Quality of any existing code</li>
<li>Scope of testing and certification required</li>
<li>How much integration work is involved</li>
</ul>
Contact us for a precise estimate.
What kind of post-development support and maintenance do you offer for Windows device driver development projects?
<p>Upon delivery, our customers have an acceptance period to verify that the driver meets all requirements. After a customer accepts delivery, we provide a 90-day warranty period, during which we’ll fix any issues free of charge.</p>
For ongoing needs like hot fixes, debugging, or resolving user issues, Apriorit offers optional post-development support as a separate service, available on an hourly <a href=/rd-services/time-and-materials-model>(time and materials)</a> basis or via a <a href=/rd-services/dedicated-teams>dedicated team</a> for large-scale maintenance. This flexibility ensures your driver remains secure, stable, and fully functional long after deployment.
Have you worked with my type of device or protocol?
<p>Most likely, yes. Apriorit has over two decades of experience developing and testing drivers for diverse devices, protocols, and environments. If you’re working with a custom device or protocol, or if your technology isn’t listed in our tech stack, share the details with us. Our experts have extensive experience in kernel and driver development and can quickly get up to speed with your technology.</p>
During an introductory call, we’ll confirm our relevant experience, present similar case studies, and share client testimonials. Our expertise spans both standard and highly specialized custom hardware.
