I thought any kernel could handle USB, this is news to me!

Royce 10 months ago

I think the controller chip is crucial too.

Blair 11 months ago

Wait, do we really need a USB 2.0 device?

Beckie 11 months ago

Totally agree, hot-pluggable support is also essential!

Emmanuel 11 months ago

A kernel with USB driver support is a must.

Dominque 11 months ago

I’m leaning towards option B being the answer, but I remember reading that the controller chip is also crucial for USB functionality.

Kathrine 12 months ago

I practiced a similar question about USB drivers, and I feel like the kernel needs to support hot-plugging, but I might be mixing it up.

Aja 12 months ago

I think a USB 2.0 compatible device is definitely needed, but I can't recall if the controller chip is essential for enabling support.

Roselle 12 months ago

I remember that USB support is tied to the kernel, but I'm not sure if hot-pluggable support is strictly necessary.

A kernel with USB driver support is definitely required, but I'm not sure if that's the only thing. I'll have to read through the options again and see if I'm missing anything.

Okay, let me break this down. We need the USB device, the controller chip, and the kernel support for hot-pluggable devices. I'm pretty sure A is the answer, but I'll double-check the other options just to be sure.

Hmm, I'm a little unsure about this one. I know we need the kernel to support USB, but I'm not sure if that's the only requirement. I'll have to think this through carefully.

This seems pretty straightforward. I think the answer is A - a kernel that has USB driver support is not required to enable USB support on a Linux system.

Joseph 1 year ago

But without a supported controller chip like DHCI, UHCI, or EHCI, USB support won't work properly.

Tandra 1 year ago

I disagree, I believe the answer is D) A kernel that supports hot-pluggable devices.

Joseph 1 year ago

I think the answer is B) A USB 2.0 compatible device.
