So Im doing a project and got a question, I have a Pi Zero with a USB-controller soldered on the tabs... so what if I connect the micro USB-port to a computer, what would happen?
1) Damage the computer
2) Damage the Pi
3) Damage the Controller
4) No damage, but you could not use the pad to controll the computer
5) No damage, and controller would work
6) Just dont do this, you could destroy everything, including planet earth!
8) stupid idea - do not do it !
The BCM2835 SoC has a single USB Bus and even with the controller connected further connecting to a PC will not achieve anything, except feasibly damaging either the Zero or PC USB.....
By default the single USB is in Host Mode, whilst your PC is also by default in Host Mode, USB works on Host /Slave.
If you put the Zero in Gadget Mode (similar to OTG) it will become a USB Slave and then the USB Controller which is a USB Slave will not function but your PC will recognise a Slave Device has been plugged in, but will feasibly get confused as 2 Slaves present on the single USB Bus.
