USB : Overview USB Is Like A Railroad |
This Master/Slave relationship between the PC or "Host" (Master) and the peripheral (Slave) means that the USB hardware on each end is very different.
A USB peripheral device does not have the right kind of USB hardware to command another USB peripheral, so please don’t expect to be able to turn your microcontroller-based USB peripheral device into something that can control another USB device like a printer. It can’t happen.
