Hello everyone, I have an unusual request, and if you will allow, a little background is in order before my request. I started writing a book on USB some time ago, when only UHCI and OHCI were available. Later when EHCI became available, I thought I should get back to it but fell short. However, now that xHCI has been released, I have returned to the dedication I had those years ago. It is a book on how to program and use the four common USB controllers, uhci, ohci, ehci, and xhci. How to find them, set them up, communicate with, and detect and communicate with any device attached. There is no platform dependency, though I use FreeDOS as the testing platform since it has no restraints to port/memory mapped I/O. Now to the request. I am in the need of a testers to verify my findings. I have multiple controllers, but would like my tests ran on other platforms to broaden my results. At http://www.fysnet.net/usb_help.htm I have a bootable FreeDOS floppy image with instructions on how to run my tests. They are nothing more than finding initial register values, PCI register values, along with a few timing routines. Hopefully later, I will have a more detailed test package. If you are willing to boot a test machine with the image given above, please run the tests included. I would prefer the xHCI test, but would welcome all four test results. Please follow the included instructions[1], preferably sending the results to the given email address. However, net etiquette suggests you post them here, though either way would be fine. Obviously, if you do not have a floppy disk drive, and fewer and fewer machines do now, you will not be able to run the tests. If you do have a floppy drive, but it is an external USB floppy drive, the test results will not be recorded since the test will reset the controller which in turn resets the drive to the default state. With a strong desire not to create a flame war, my primary development platform is not Linux or Unix based. Therefore, I do not have the knowledge to develop these tests for a Linux based platform. I apologize for this, and ask that any derogatory remarks be kept to a minimum. Thank you for your time, Benjamin David Lunt P.S. I tend to include the names of all who have assisted in any way. If you do not wish for your name to be included in my book, please let me know in your reply. Thank you, Ben [1] The included instructions are designed for a DOS based platform using the included INSTALL.COM app to install the image to a floppy. However, since you most likely will be using Linux, please use the Linux based procedure to copy an image to the floppy device. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
