It's been a while since I took another look into this, but I have a lead that this forum could possibly help with. On a side note, the Arduino forum was not very helpful at all. The only thing that I could think of was if the Arduino was being driven too much power (or if the power is inconsistent somehow), and the switched I have in the dance mat are acting as capacitors and letting some current through. I haven't done any measurements or math to look into this, but it seems very unlikely to me.

Asking chatgpt, I got lead to check permissions of the usb device, and even giving the decide all permissions does not help. However, I decided to check the dmesg log, and noticed something. I am transcribing this from a photo I took of the text on a CRC tv, so I apologize if there's errors.

A couple things I noticed here: The arduino is being read as an input into input 4, and it is being read as a HID joystick into input 2, and it is being read as an ACM device. Do any of you think that being registered as multiple inputs/systems could cause the issues I am seeing? And if so, how can I make Debian only recognize the arduino as one device? I am not linux savvy enough to know how to do that.

Thanks!

So, there is no way to make this work? :(

I don't think so, but since it's also not working in Windows, the board may be broken ?

I found this mail chain reporting some fix in Ubuntu 19.10 for another very similar Saulabi model, I don't know if helps in any way : https://www.mail-archive.com/search?l=ubuntu-bugs@lists.ubuntu.com&q=subject:"[Bug+786955]+Re%3A+Saulabi+4K+Joystick+(Buttons+not+working)"&o=newest&f=1

That doesn't seem to have any useful information for your problem.

Could someone publish this patch on
RetroPie-Setup/scriptmodules/supplementary/customhidsony ?

yes, I've posted to DFRobot Bluno Bee forum. Hopefully, there'll be a reply soon.

There's a suspicion on the Raspberry PI forum that BLE devices are not supported in Raspbian. Interesting ...

Anyway, if anyone has a BLE device or gamepad working in RetroPI, that'll help a lot!

@rbaker Hi!
retroarch.cfg I'll post few hours later, when I'll get home.

Regarding power supply - I use an external 5V 2A USB power adapter and the joystick works fine in Emulation Station, I can scroll pages, select menu items, etc. with it, but it stops working in any configuration tool from RetroArch I try to start.
