Maybe you did not install the USB HID quirks for Raspbian? It is a known issue with the older Linux kernels and is described here in the section "Installing USB HID Quirks for the GamepadBlock" at https://blog.petrockblock.com/2017/10/10/tutorial-gamepadblock-raspbian/.
Doh, OK, re-running the script after rebooting fixed it. I must not have rebooted since updating the kernel version. Now I can run jstest /dev/input/js0and see the buttons work as well as shutdown view soft power switch and see LED indicate status.
I'm not sure if this post will be useful to others, but one never knows. In any case, the process of writing it out probably helped me figure out what went wrong.
I don’t know the exact pi out of the pi2scart, but you can find the used pins of the PowerBlock at https://blog.petrockblock.com/powerblock-raspberry-pi-power-switch/:
S1: pin 12
S2: pin 11
If this does not collide with the pi2scart, it should work.
I have just pushed an update for the ControlBlock driver. You can now connect a button to P2, "A": Pressing that button will lead to a simulated press of Start + B, as well as a keyboard button press of "F1".
Does this work for you?
You mean you need a tutorial for updating or reinstalling the PowerBlock driver, right?
What you could try is to run
wget -O - https://raw.githubusercontent.com/petrockblog/PowerBlock/master/install.sh | sudo bash
from the command line to execute the auto-install routine of the PowerBlock driver (as described at https://github.com/petrockblog/PowerBlock#quick-installation). Maybe that solves your issue?
Can you post the output here?
I just checked the installation script with the current RetroPie image and everything went fine for me. I have also added a screencast that shows the console output for the installation. You can find it in the "Videos" section at https://blog.petrockblock.com/powerblock-raspberry-pi-power-switch/.
@paulkosm I think this is just the nature of the powerblock. The problem would be that the latching switch would still be latched in the on position (which is why you get a restart) and there's no way to automatically unlatch it. It might be more annoying to have to unlatch then latch again to turn the system on after a soft shutdown.
Personally I just use the powerblock switch to shutdown every time and never use the menu shutdown option now.
I know this is an old thread but I'm just getting into RetroPie (and Raspberry Pi's in general!)
@LeatherOtter Out of curiosity, did this end up working the way you expected? If so, I'm thinking the Powerblock might be a very easy way to modify my just arrived Retrflag NESPi case to make the power and reset buttons functional as expected. The Power button would just shut it down, and the reset button (which just momentarily cuts power) would cause a restart.
