@lostless said in RPi4 USB ports guide: @gordonfreemanjr Ignore what the controller is showing on its LED face. I agree. My bluetooth Wii U Pro clone gamepads also only light the first player LED even if they are working fine for different players in Retropie.

@mitu After running lsusb, I can see the adapter as follows: Bus 001 Device 004: ID 1292:4154 Innomedia Retro Link Atari cable Using the vendor and product codes from above with 0x appended to each to look up 0x1292:0x4154 with the search term quirks, I found documents referencing this is the option that corresponds to the vendor and product info for my device: options usbhid quirks=0x1292:0x4154:0x040 Some of these include the following sites: https://github.com/libretro/Lakka-LibreELEC/blob/master/packages/libretro/retroarch/modprobe.d/usbhid.conf https://github.com/msteinbeck/hid-retrobit/blob/master/DETAILS.md I edited the /boot/cmdline.txt file and added the following to the end of the line of text: usbhid.quirks=0x1292:0x4154:0x040 After rebooting, I can use the following commands to test that both controllers are working: jstest /dev/input/js0 jstest /dev/input/js1 Thanks for the help!

Try to test the encoder using jstest - (see here) - to check if the joystick and buttons produce correct results. Is there a schematic you've followed to wire the joystick and buttons to make sure they're correctly wired ? Or does the encoder has labels for each connections indicating the correct wiring ?

@mitu thanks very much for the quick reply

I should probably just tell you that i did order and received the 2x Tomee NES to USB adapter. They work flawlessly with my two original NES-004E controllers. I have been using them for the past 2 weeks playing top NES games. :-) I am still waiting for the PSX to USB adapter to arrive. At the moment i have no way of testing my PSX Analog controller.

@tjayhawk32 I don't think the order matters. The Pi has only 1 internal USB hub, any port would go over the same data path.

@mat Element 14 is one of the main distributors for raspberry pi, it is probably as official as it gets.

Please include the information requested https://retropie.org.uk/forum/topic/3/read-this-first in when opening a support topic. Have you read the documentation for enabling a 6 button controller in RetroArch ?

Final Update: Turns out it was my charger all along . Here is what I ended up doing. From my Pi3 I run a DC Barrel Jack to Micro-USB B Male Connector (http://a.co/d/4yVdU3c) . Then from the barrel jack I have a normal power supply (http://a.co/d/7j0vMr3) . No voltage issues at all and everything seems fine.

@cyperghost Alas, I don't now how ES and its emulators will react to this on runtime. I didn't use it myself (yet), but researched it only because of this thread and a general interest for future use. As for specific drivers, I don't have any experience in that either, but as long as they depend on the devices in /dev/input/, they should react to disabled devices there accordingly, I suppose.

@edmaul69 Great :-( Thanks for the warning

@chrisbati Unfortunately, c64 and spectrum joysticks only had one fire button command, no matter how many physical buttons there were. The adapter may support more buttons on the output, but if it has no difference in the incoming signal, it won't be able to do anything else.

For default controller mapping here is a link: https://github.com/RetroPie/RetroPie-Setup/wiki/RetroArch-Configuration#default-joypad-hotkeys Oops mitu just beat me to it

@xd3l Turns out that I can't use any of my USB hubs with this. If I do, the Tomee Adapter doesn't pick up, though everything else does. If I take the hub out of the equation then the NES adapter works every time without issue. This is unfortunate because I was hoping to rig up a player 2 port, thus needing a USB hub.

Ah... Thanks DD_Indeed. I'll give it a shot tomorrow and see how it goes.

@richiep I have the deadzone issue as well. I'm using the Ram controls USB adapter, and I think the deadzone is programmed in the controller. When I run a jstest on it, I can see the deadzone in the numbers, so I haven't gotten into the mame settings. I use advmame, so I'm not sure about the parameters in Mame4all, but there must be some. Can you try advmame? What is the USB adapter you're using? I was going to try to configure a Teensy. ws
