Writing Drivers

Hello,

I have a new laptop, and I wiped the drive to put an older OS on it. Unfortunately, I cannot find any drivers for my USB 3.0 that work with my OS. I searched for hours online and could not find any options.

I've decided to try and write one myself. I have limited computer / software experience.

How arduous a task is it to write a driver?

What languages are they written in?

I know that I have to link my OS with the USB device and I have to know how my processor handles threads, interrupts, etc. But, do I have to consider my computer's design also?

Thanks.
 
How old of a OS? I know most make USB 3.0 for XP still.

Really? I have windows 7.

But, doesn't the driver have to work with the peripheral device in question (here my USB 3.0), the processor I'm using, the operating system, and even the computer itself e.g. the motherboard?

Where can I find a driver that will work for me?
 
What motherboard do you have if its custom built or model of pc if its store bought?

I don't know what motherboard I have, but my computer model is Toshiba c55d-b5212, brand new laptop.

Is there a way to see what motherboard I'm using without having to open the case?
