i was wondering if someone did a library to make the arduino a USB Host (sure low speed 1.5Mbs).
I know that there is some hardware solution out there but i want to be on the low cost.
i would like to interface a Yubikey. it’s generate a one time code, and to the host it is exactly as a HID (Human Interface Device, or Keyboard)
And if nobody did it do you think that a simple dedicated USB host (to keyboard) would be feasible in the 16k/32k of the Arduino
