I am a service engineer with 15 years of experience and I am constantly looking for drivers for various hardware for work. I’m tired of using bad sites and I created a good one – you are on it. Enjoy using the site. Unfortunately, I have never held 70% of the hardware for which I publish drivers in my hands, and therefore some drivers may not work. Humble yourself.
