USB Hosts Everywhere. Become the Expert Who Makes It Work!


From consumer electronics to industrial automation, USB is the backbone of modern embedded communication. But mastering USB hosts at the bare-metal level is a skill very few engineers possess.

This is your opportunity to join an elite group of firmware developers who can design, optimize, and write USB host drivers from scratch.


No Abstraction Layers. No Black Boxes. No Guesswork.
In this course, you’ll go beyond high-level libraries and learn exactly how USB works at the hardware level.
You’ll build your own USB host controller driver from the ground up—handling interrupts, managing channels, parsing descriptors, and implementing real-world USB applications like mass storage for connecting flash drives to your embedded devices, HID keyboards, and mice.


By the end of this course, you won’t just understand USB—you’ll be able to engineer robust, production-grade USB host firmware for real-world devices.


We’re talking about...

NOT Relying on Pre-made Frameworks or “black-box” Code.
What Your Embedded Device Can Do with USB Host Capability


With USB host functionality, your embedded device becomes a powerful hub for data exchange, peripheral connectivity, and real-time processing. Whether it's automating industrial workflows, enabling smart home integration, or enhancing AI-driven edge computing, USB host firmware expands the capabilities of your embedded system like never before.

The Low-Level Transformation You’ll Experience:
  • From Clueless to Confident in Baremetal USB: Ditch the guesswork and limitations of pre-packaged libraries. You’ll learn to configure every parameter manually—speed, PHY settings, class integration—so you have total control over device performance.
  • Build Drivers from Scratch Like a Pro: You won’t just call “init” functions someone else wrote; you’ll step into their shoes and code your own usb_core_init, usb_core_reset, and endpoint routines. This is the real deal—the kind of skill set that wows employers and clients alike.
  • Develop real-world USB host applications for storage devices, keyboards, mice, and more.

Addressing Your Pain Points and Fears
  • I don’t want to rely on black-box solutions.” Perfect! This course is all about going baremetal. You’ll decode registers, control endpoints directly, and handle interrupts yourself. No shortcuts—just professional-level knowledge and authority.
  • Isn’t starting from scratch slow and confusing? ” We’ll provide a structured roadmap. Each module builds your understanding step-by-step, ensuring you never feel lost. By the time you finish, you’ll be writing low-level code with a speed and confidence you never thought possible.
  • Will I ever use these skills for real-world products? ” Absolutely. Companies pay top dollar for engineers who can debug from the hardware up, optimize performance, and quickly adapt to new hardware requirements. This training puts you in that elite class of engineers.
What You’ll Master, Step-by-Step
  • Core USB Concepts & Environment Setup: You’ll dissect USB protocols (from USB1.x to USB4), lay bare the descriptor configurations, and learn to choose the right STM32 hardware for your build.
  • Low-Level USB Driver Construction: Design and implement every element of the driver yourself—no relying on someone else’s library. You’ll tackle USB_OTG_CfgTypeDef, usb_core_init, usb_core_reset, and even your own interrupt service routines.
  • High-Level CDC,HID,MSC and Beyond: After building the low-level foundation, you’ll ascend to creating a Communication Device Class, Human Interface Device Class and Mass Storage Host Class that integrates seamlessly with everyday devices.
  • USB Enumeration & Data Flow: Understand every step of how the host recognizes, addresses, and configures your device. You’ll ensure smooth, error-free data transfers using your own endpoint code.
  • Power & State Management: Fine-tune active, suspend, and resume states, ensuring your device maintains efficiency and performance—hallmarks of a truly professional design.
  • Practical Implementations (HID, MSC): Recreate everyday hosts from scratch, an embedded device that connects to—a USB keyboard, a mouse, or a flash drive —gaining insights into how consumer electronics achieve plug-and-play perfection.
Who This Is For
  • Embedded engineers serious about going “under the hood” and mastering USB like industry pros.
  • Developers tired of black-box libraries who want full understanding and control over their firmware.
  • Innovators who want to build unique, next-gen USB devices—think custom sensors, HID VR/AR controllers, or integrated gesture inputs—that delight end-users.
