interfacing 8086 with usb

[saeedmmmm]

Hi everyone!
Is there any way to interface 8086 with usb? I need its simulation in proteus.
And how can i do that with 8051 instead of 8086?
Is the circuit in link below true?

Thanks all

The circuit is wrong. You need USB to TTL converter.

The circuit is wrong. You need USB to TTL converter.

I guess you mean USB-to-serial bridge, e.g. FT232.

Thanks FvM! Is there any library for FT232 in proteus?

 

[FvM]

Obviously not. Proteus is supporting USB communication simulation for a few USB microcontrollers only.

Thanks for reply. I tried Altium designer too, but it seems doesn't have FT232R simulation model file too.
What simulator should i use? I have a project with the final circuit like this: https://chetanpatil.info/1/post/2012/03/interfacing-usb-lcd-8051.html
I'm really grateful helping me doing this project.

I don't know what you want to achieve with simulation in this case.

Regarding the said link, jayanth already stated that the circuit can't work as shown.

It's not even clear what's the intended pupose of USB interface in this case. Apparently the author has only vague ideas about USB, e.g. when he mentions communication with USB sticks, which actually requires an USB hist interface.

My project is simulation of receiving data from USB and showing it in LCD display.

I fear that won't work. Contact your tutor to update the specification.

It might work with a PIC18 USB controller and Proteus.

Is there any way to load a code or firmware into 8051 or 8086 to work just like PIC18 USB controller? I mean like v-usb for AVR: https://www.obdev.at/products/vusb/index.html

I didn't expect that you are referring to VUSB or a similar solution. It's limited to low speed USB. It surely can't work with standard 8051 that is working at 1 MIPS only. And it rarely can be simulated with Proteus.
