RetroUSB SNES to USB Adapter buttons not recognized properly

[thorr]

Hello,

I have been using a RetroUSB NES to USB adapter without problems. Today I received a RetroUSB SNES to USB adapter. I tested it on my PC and every button works properly and maps to different buttons. When I connect it to my Mister FPGA, the following buttons both act as the same button:
A and B
X and Y
Select and L
Start and R

When I am defining the buttons from the menu, once I press A for example, I can't press B (or A) for any of the following button assignments because it was already defined. Once I press X, and I can't use Y, etc. After mapping, I can press A or B and they both act the same. I tried turning off fast USB polling, but it did not help.

Do you have any suggestions to try to fix this? Thanks!

Update: It is being detected as a two axis, two button gamepad:

Windows sees it as having 8 buttons.

Any help would be appreciated. Thanks!

I found this site that shows a similar issue: https://askbot.fedoraproject.org/en/que ... f-buttons/

In his case, the kernel version was affecting the number of buttons showing up.

$ uname -a

$ jstest /dev/input/js0
Driver version is 2.1.0.
Joystick (RetroUSB.com SNES RetroPort) has 2 axes (X, Y)
and 8 buttons (BtnA, BtnB, BtnC, BtnX, BtnY, BtnZ, BtnTL, BtnTR).

$ uname -a

$ jstest /dev/input/js0
Driver version is 2.1.0.
Joystick (RetroUSB.com SNES RetroPort) has 2 axes (X, Y)
and 4 buttons (BtnA, BtnB, BtnC, BtnX).


In my case, I was looking at the wrong device. Mine actually is showing as having 4 buttons which makes sense because it has 8 and they are paired up giving me 4 usable.

So, I am guessing a Kernel update might fix my issue, but I have no idea.

Same problem here. Here’s hoping the right people will see your posts and fix the issue via a kernel update.
BTW, the Raphnet SNES to USB adapter does not have this issue.

Here is a patch for the kernel to fix the RetroUSB adapters: https://github.com/torvalds/linux/commi ... 31cdeb3d26

Apparently they need the HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE quirk. You can test this by adding usbhid.quirks=0xf000:0x00f1:0x100000 to /linux/u-boot.txt

Thank you for your help. I tried putting the line you suggested all by itself to take out any other variables, and it did not change anything. I have ordered a ralphnet adapter in the meantime (waiting for it to arrive), but I would still like to get this working just because. Do you have any other suggestions about what to check in order to get the line in the u-boot.txt working correctly?

Not sure if something changed on the MiSTer side, but I've been using the RetroUSB SNES to USB adapter to connect a OEM SNES controller to my MiSTer for the past four months and it has worked flawlessly. I didn't have to do anything special.
