Hello,

in my 100% assembly operating system, i NEED to use usb port to connect my camera. If my UEFI integrates usb boot, does that mean that it already manage usb port, i mean all its features ? If yes, are there interrupts to do that ? If not, do you know if this site http://www.usb.org/developers/docs/ allows me to write a driver with all features of USB 3.0 ?

Thanks in advance. What operating system is this? Are you making your own OS? I don't know a thing about writing device drivers, but I'm curious.Yes but i am not a competitor to Windows and others, that is intended to a robot.Would you be able to EXPAND more on this project? I really can't THINK of a reason to build your own OS for anything other than a simple learning project (which you wouldn't need USB for) when there are already so many different existing operating systems out there to fit basically every project. And even then, you wouldn't do it entirely in assembly - You would maybe have to write the EXTREMELY low level bootloader.etc in assembly but you would then write everything else in a high level systems language like C.
It has nothing to do with the topic but this OS is intended to control a humanoid robot. I know what I'm doing and assembler is my choice. Please i need the answer as soon as possible.Quote from: Block on July 31, 2016, 12:48:29 AM
