I am still interested in your help. If you have a chance, please have a look at this page. Have a look at my Figure Eight page that shows how to create your own USB Device. Have a look at my ATTiny2313 device that doesn't "hard code" the LED's to the board. You can attach it to a bread board and use it as you please. USB: The Universal Serial BusThis book is for those who are building an operating system, writing embedded code, or just want to learn how to communicate with the USB hardware and attached devices directly through hardware programming. This book will show you how to find and initialize each of the four major USB Host Controllers, set up USB stacks, and communicate with attached devices. It has detailed information and examples of each step required to accomplish this. Detailed information for the UHCI, OHCI, EHCI, and the new Super Speed xHCI controller is easy to follow and understand.

General Frequently Asked Questions about this Book Series are found at the main book page.

A Frequently Asked Question list about USB device driver development can be found here.

Frequently Asked Questions (about my book):
  1. Q: USB looks complicated. Should I even learn USB in the early stages of my development? A: First, don't be discouraged that you might not wish to start so early in to USB. Though I agree that USB might be difficult and probably not something a newbie should be starting with, I will tell you that the USB is and can be a most enjoyable part of your learning experience. Therefore, if you wish to start USB now, for the joy of it, this would be a perfect time to do so, though keep in mind that a successful implementation will need other parts of an OS system already implemented.
  2. Q: What other components of the Operating System must I implement to be able to use USB? A: You will need a working knowledge of the PCI(e) system to be able to find the USB controllers, and you will need some sort of accurate timing system for accurate delays as well as other time sensitive parts of the USB. For the timing, you can read the (dated) RTC clock, the (dated) 8253 Timer, the newer APIC clock, or even the most recent HPET clock. I discuss, in detail, the necessary parts needed of the PCI(e) bus in Chapter 2 of this book.
  3. Q: Using your book, will I need to buy any other hardware to test my code? A: If you are using system emulation exclusively, such as QEMU or Bochs, you will not need to purchase any extra hardware. Each of these emulators with emulate the necessary hardware needed. If you wish to test your code on actual real hardware, then of course you will need the actual hardware to test with, whether you purchase it or borrow it.
  4. Q: Of the above questions, what specifically does this book cover? A: This book covers the process of programming the USB from the beginning. It starts by describing the PCI enough to find the USB controllers, determine which type it is, and how to find other information about the controller. The next section shows how to setup and use each of the four controllers, each description independent of another. The next section shows how to enumerate different devices in general while the next section goes into detail about the types of devices that can be attached. These devices include Mice, Keyboards, MSDs (Mass Storage Devices) such as thumb drives, External Hubs, and Printers. I have given as much detail as possible to be able to successfully setup a controller, attached devices, and communicate with said devices to read mouse coordinates, keypresses, sectors from a thumb drive, status of external hubs, and send images to a printer. Details include, for example, the difference between full-speed thumb drives and Super-speed thumb drives and the different interfaces used.
  5. Q: What specific devices do you use as examples and detail in your book? A: Most commonly available devices, such as:
    • HID devices: USB Low-speed keyboards and mice, using both the default boot protocol, as well as parsing the HID descriptor(s) to use the HID protocol packets. Included is a complete chapter specific to HID Descriptor Parsing containing complete source code.
    • MSD devices: Mass Storage Devices such as USB hard drives, thumb drives, and floppy disk drives. These come with difference protocols such as Bulk-only BBB (Bulk Bulk Bulk), UFI CBI (Command Block Interrupt), both with Interrupt and without, and the new UASP (USB Attached SCSI Protocol) taking advantage of xHCI Streams.
    • External Hubs and Rate Matching Hubs, including how to get the status of each port, as well as other needed information pertaining to devices attached.
    • USB Printers: Information is included to determine what type of printer is attached and what protocol you can use to send text or images to the printer. An example of printing an image is included.
    • USB Cameras: Information on using ISO type transfers with High-speed cameras, including source code to receive full screen images.
    • Information is included on known quirks of each type of device, such as getting the capacity of a thumb drive. Some manufacturers return the count of sectors available while other manufacturers return the address to the last sector available. This will always be a difference of one sector depending on the technique used.
  6. Q: In your book you describe the use of a USB analyzer and show how to see the traffic that is sent on the actual wire. Do I need one of these analyzers? A: The analyzer in question is from TotalPhase and if you have a look at their website, you can see that these wonderful little pieces of hardware are quite pricy, at a price of about $500 US Dollars. Though it is not necessary to use this book, it was a great benefit to my development to see what data is actually being sent, the timing between each packet, and the sequence of these packets as they are sent back and forth between the host and the device. For your benefit, I have given examples shown in memory dumps to show this throughout this book. Therefore, unless you are very serious about USB, plan to create devices, and/or work for a company, the purchase of an analyzer is not at all necessary when using this book. However, I highly recommend an analyzer such as the one linked here if you wish to be a serious USB hardware programmer.
  7. Q: Your book mentions that I can create a USB device and shows how to do so. What do I need to do such a thing? A: The freely available Appendix Q of this book shows in detail what you need to do create a simple USB device. It shows what compiler is needed and how to use it, what electronic items are needed, such as resisters and capacitors, as well as a few examples of IC boards. You will also need a little knowledge on how to use solder and a iron correctly, as well as a few misc items. The example given shows how to blink an LED, and I have other examples freely avaliable, such as how to create a 7-segment digit display and send digit values.
  8. Q: What is the difference between Jan Axelson's book and your book? A: Her book explains quite well how to use the installed operating system and its functions (and additional libraries) to access the operating system's USB functionality, detailing the communication between the host and the device, but not how it actually gets sent and/or received through the host's installed hardware. My book explains how a (non-specific) operating system communicates with the attached hardware to pass the commands and data back-and-forth between the attached devices and the host operating system, those commands and data packets her book details. My book also explains the hardware side of the USB that is used to do this from the operating system's point of view, not from the user's point of view.
  9. Q: Do you have a Frequently Asked Question list about USB device driver development? A: Yes. You can find that FAQ list here.
