I am attempting a project that is a basic usb keyboard logger. I plan on using a PIC32 microcontroller that has built in USB host capabilities to interface to the keyboard.
My question is, can i hang off in parallel my MCU to read the data lines without affecting what is sent to the computer? See the below picture.
Is this acceptable practice, or does the data need to be fed in series from the input->mcu->output connector? Any issues with current draw?
