Controller and Bluetooth Information

Aditional note

While I've fully embraced Linux for my everyday computing, I still consider myself a Linux 'noob'. I'm more than willing to share any additional information if needed and am open to following instructions for any potential solutions. Thanks in advance for your assistance!

This is a problem we cannot really control from the driver. There are multiple causes for this:

  • Bluetooth driver problem or chipset incompatibility: the UB500 falls into this category, UB400 may work better
  • too fast rumble commands from user-space bypassing the driver crashes the firmware: if SDL or other hidraw clients use direct rumble commands, we cannot control this, disable Steam Input and/or access to hidraw
  • xpadneo really is a HID driver, it doesn't see Bluetooth at all, leaving us with no chance to control anything Bluetooth-related

Depending on the firmware version, the firmware can crash on rumble:

  • via USB (includes the Xbox ACC dongle) if intervals fall below 10ms (Windows drivers seem to force intervals of at least 10ms)
  • via Bluetooth on older firmware if intervals fall below 20ms (all modern SDL versions should work around this)
  • via Bluetooth on newer firmware if intervals fall below 50ms (recent SDL versions should work around this)
  • the Linux kernel uses 20ms intervals but doesn't prevent the issues because 20ms is per effect, not per command
  • xpadneo currently forces intervals of at least 50ms, this causes frequency aliasing with ff_memless resulting in uneven rumble effects (xpadneo v0.10 is planned to work around this)

You can check if rumble is the problem by turning rumble off: set attenuation to 100 in the module options. If games still rumble, SDL/Steam Input use hidraw: Try turning that off. If rumble is completely gone now, you can turn driver rumble back on and see if the problem persists.

But I believe you should rather look into Bluetooth issues:

  • if possible, try a different chipset, e.g. UB400 (CSR-based) instead of UB500 (Realtek-based)
  • look into bluez latency and interval settings: https://github.com/atar-axis/xpadneo/blob/master/docs/TROUBLESHOOTING.md

Tried the tweaks you suggested.

Changed the attenuation to 100 in the /etc/modprobe.d/xpadneo.conf Added the 'SDL_USE_HIDAPI=0' in the /etc/environment

Quick rundown:

  1. Disconnected after about a minute.
  2. Reconnected, and the Steam Controller Tester's rumble option vanished, played nice for 5-10 minutes (the longest uninterrupted session so far).
  3. Disconnected again, rumble option came back.
  4. Repeat.

Thanks for the quick response and guidance. Apologies if I misunderstood any steps. Will try to get a different adapter soon, and I'll report back if anything changes.
