XBOXDRV Guidance Needed
@mediamogul Thanks, I'll take a look at it soon as I finish dinner!

So these "paths" will never change as long as I keep the adapters connected on the same ports?
EDIT This still won't work for me. I did an evtest of each
event-joystickand it only gives me the player 1 port of the adapter.
Did two listings show up with

@mediamogul When I do
ls /dev/input/by-path, I get this:

I tested each
event-joystick, and I came up with this:
Xbox platform-3f980000.usb-usb-0:1.2:1.0-event-joystick Raphnet platform-3f980000.usb-usb-0:18.104.22.168:1.0-event-joystick MayFlash platform-3f980000.usb-usb-0:22.214.171.124:1.0-event-joystick MayFlash platform-3f980000.usb-usb-0:126.96.36.199:1.1-event-joystick
So while it would work with the MayFlash (Atari/Sega) it only saw one entry for the the Raphnet (NES). When I do an generic
evtestI get this:
No device specified, trying to scan all of /dev/input/event* Not running as root, no devices may be available. Available devices: /dev/input/event0: Xbox 360 Wireless Receiver /dev/input/event1: Microsoft Microsoft® 2.4GHz Transceiver v8.0 /dev/input/event2: Microsoft Microsoft® 2.4GHz Transceiver v8.0 /dev/input/event3: Microsoft Microsoft® 2.4GHz Transceiver v8.0 /dev/input/event4: raphnet.net nes2usb /dev/input/event5: raphnet.net nes2usb /dev/input/event6: Mayflash Ltd Mayflash MD USB Adapter /dev/input/event7: Mayflash Ltd Mayflash MD USB Adapter
So it looks like it sees multiple events but for a single device (which makes sense). But it doesn't do it that way with the MayFlash.
EDIT - If I run
evtest /dev/input/by-path/, I get this:
evtest: can't get version: Inappropriate ioctl for device
EDIT 2 - If I run
ls /dev/input/by-id, I get this:

Looks like it's only seeing 1 raphnet there too. :(
The adapters that have multiple ports are notoriously difficult to map outside of Windows and they're all pretty much set up the same way. An example that I've worked with personally is the Mayflash Gamecube to WiiU adapter. In it's USB mode, all the ports register as being one device also. The only way I could get it working with my RetroPie setup was to use Toadking's driver in WiiU mode. It's been a while, but as I recall, there's a certain aspect of the USB HID spec that is responsible for delineating the multiple ports and it's unique to Windows for some reason.
I think I need to do this:
Looks like your right as per:
"The way multi-player adapters and boards are implemented make them appear as one single controllers in Linux. For instance, the adapters based on the 4nes4snes board (eg: Four SNES to USB) used to register as a joystick with 4 pairs of axes, and 32 buttons (8 per controller). But at some point, this became 2 axis (a mix of all controllers) but still 32 buttons.
To fix this problem, I wrote a kernel patch to make the adapters appear as a set of independant controllers in march 2015 and it was included in the Linux kernel starting at version 4.2.0. With this patch, things are cleaner than ever. But as 2016-05-02, the kernel included in the RetroPie SD images is still one of the 4.1 series... So besides waiting, what can one do? Of course geting the kernel sources, applying the patch, compiling and installing it! But there is an easier way."
This will likely do the job and it's great to see that this addition is waiting around the corner in a future kernal update. Seeing as how several adapters use this same method, hopefully this will solve the issue all around.
Yeah I tried to run his script to update the
cmdline.txtbut it didn't work after rebooting. I think it's because I've updated the kernel in the past without including his patches. So I'm going through that now. Gonna take a good couple of hours. I sent his support email a message though to see if he suspects the problem I'm having is related, and see if he has any tips or suggestions.
Let me know what he says. This is an interesting development and I might make use of it myself sometime in the future.
Sure thing. It's interesting the things we discover along the way trying to solve a problem. This all started because I wanted to get the latest version of RetroArch to have Leaderboard support. That led to the config files getting broke and needing to get replaced with the generic default. That led to all the custom changes I did for my controllers to work on the fly to disappear and stop working. Now I'm back to rebuilding the kernel so I can have a more permanent XBOXDRV solution. I still can't figure out why nobody else is having all these problems lol.
Ha! Let's face it, solving these issues is the real game, saving the princess is just a bonus round.
@mediamogul You sure got that right! But this is fun too. This is what keeps me spending money where I shouldn't. :)
Well after fully rebuilding the kernel with the correct patches, I'm still having the same symptoms. My Raphnet NES2USB adaptor is being identified with 2 event ID's, but only one device ID.
This ONE hindrance is causing me ALL my issues. :( If I can distinguish a specific device for Controller 1 and Controller 2, I'm SOL. Does anybody have any idea on a different approach here?
Does anybody have any idea on a different approach here?
Seeing as how the focus has shifted to something so different, it might help to start a new thread focusing on these types of multi-port adapters.
@mediamogul I agree. I'll continue to update in a new thread.
