#52615 With USB, to get the host's attention as a low-speed device, a pull-up resistor must be between D- and VCC... but I'm not sure if the pullups on the ESP are reliable enough to be that pull-up. If that is possible, we could have USB on the ESP with 0 external components. I've just read so much about various properties of the pullup resistors. Does anyone know if they would be suitable?

#52639 From my experience probably not, very weak pullups, very!
