Just beware that porting V-USB to ESP is quite a big challenge, because current V-USB has a lot of AVR dependencies.
Also, beware that WiFi activities can disturb the critical timing of V-USB interrupts, so maybe you will need to turn off WiFi during the USB transactions.

- Sun Jul 10, 2016 8:24 pm #50538 I was wondering now that I have learned of the esp8266 esp-14, timing is no longer a problem because there is a separate 8bit micro-controller that can support vusb. The problem I need help with is that all(most) vusb tutorials and wiring diagrams deal with 5v micro-controllers(zener diodes). In a earlier post it was mentioned that the zener diodes that are used in 5v vusb circuits are NOT needed because the esp8266 runs at 3v. Does this mean that I can connect two io pins on a 3v micro-controller directly to the D- / D+ of a usb host for vusb?
