Hello,

Recently, I was searching my Dell INSPIRON laptop, and I noticed that there is something called "USB Emulation". I searched the web for this term, but I got ambiguous answers. I read that USB Emulation is related to treating the USB as Floppy drive or hard drive when plug it in the computer, so how it makes differences in my computer, and how it affects reading my USB drive? The options for the USB Emulation is "Enable" or "Disable". Please give me any clarifications for it.

Thanks

Basically your laptop can emulate the HID USB interface for you and pass it through to your OS as a PS/2 interface if your OS does not have the appropriate HID drivers to support the USB keyboard/mouse.

If you are using an OS and USB...

USB Emulation is BIOS option in dell related to USB Keyboard and Mice,
it's useful only in bios if you enable it, bios will control USB in that stage, until operation system is loads,

basically if you control laptop using separate USB wired or wireless keyboard or mice, and it does not want to work in bios, you enable it so you can control bios

It is usually disabled by default

If you are using an OS and USB keyboard/mouse without proper driver support, put it to "enabled". If you are using a modern version of Windows, just leave it as disabled since Windows ships with the proper drivers.
