  • Sorry, but this is not clear. A USB port certainly cannot display anything, and I doubt you can type simultaneously on two keyboards. Jun 29, 2021 at 12:43
  • no no. sorry if not understood. its my bad. i want to type in single keyboard and want to display on two pc. in keyboard emulation example, otg port i am connecting to pc that i want to see on another pc also. single keyboard(single input) and two output like 2 otg. but in rpi4 only one otg is there. so i have to use one usb if possible. so usb can be used in such a way?
