- Tue Jul 05, 2016 5:20 am #50225 What I want to do, is :

PC <-> WiFi router <-> ESP8266 <-> USB-TTL <-> USB device (such as webcam).

I need the help in -

* Choseing USB-TTL: Will CP2102 module I have will do? I am thinking about attaching female port to USB part

*ESP8266 programming: Will a transparent bridge cut it? I am thinking of using virtual ports at PC side.

So You need to have USB Host instead of CP2102 USB Device. Another thing is Your "USB device (such as webcam)" - it seems like You have no idea about how different devices on USB works so as I said - study USB specification first...

Even at the max baudrate 921600, you won't get the speed require for video streaming.
Also, like Pablo said, it is not simply question of changing USB connector time, there is no software/driver on ESP to do USB Host OTG.

I have some Idea. And I know what you said about "USB Host instead of CP2102 USB Device".
But what I meant by "I am thinking", I mean how can I modify it to?
