What's the problem? Describe what went wrong.

When the controller is disconnected and then reconnected is like if I continuously pressed «Up» (on the D-Pad or Control Stick). It doesn't matter if the controller was already connected before starting the game, or if the controller is connected afterwards. In both cases, if I disconnect the controller and then reconnect it (without quitting the game), the issue occurs. I can reproduce this issue with both a DualShock 4 CUH-ZCT1E (connected through USB or bluetooth, using the "hid_sony" driver in the Linux kernel) and an Xbox 360 USB controller (using the "xpad" driver in the Linux kernel).

Note: the issue always occurs when I reconnect the controller with the game started (so it is 100% reproducible, at least here). Also, the issue doesn't prevent me from using the controller (e.g.: I can use the «A» button on the controller to enter a menu o make the character attack).

Note²: I can reproduce this issue only on SoulCalibur II (USA), with other GameCube games (and Wii games as well), such as Mario Kart Double Dash and Sonic Riders, the issue doesn't occur.

What steps will reproduce the problem?

  1. Connect the first controller (now or after you started the game).
  2. Start the game "SoulCalibur II (USA)" with Dolphin (dolphin-emu, dolphin-emu-wx or dolphin-emu-nogui, it doesn't matter).
  3. Press the Start button to reach the MODE SELECT screen.
  4. Disconnect the first controller.
  5. Reconnect the first controller and you should see the modes are automatically selected, just like if you were continuously pressing «Up» on the D-Pad or Control Stick.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, version (as shown by dolphin-emu-nogui --version): "Dolphin [HEAD] 5.0-7735-dirty" (commit 3d44dc39814197e43bf1b8c2524684252251ee7b).

Is the issue present in the latest stable version?

I tried to reproduce the issue with the latest stable version (5.0), but apparently it doesn't have hotplug support yet (when I reconnect the gamepad it doesn't work at all, in any game).

configuration files, savefiles, savestates)

Works fine when using GameCube Adapter for Wii U.

Could you get a screenshot of the controller configuration screen before and after the glitch?

#2 Updated by Scall almost 3 years ago

There are no differences in the controller configuration screen before and after the glitch (the red dot of the control stick is always at the center and doesn't move, unless I move the stick on my controller; also, the D-Pad assignments are not highlighted, unless I press it). You can take a look at these videos I recorded: - part1 - part2

#3 Updated by Scall almost 3 years ago

I cleared the controller assignments just to do one more test, but I've seen that reconnecting the controller is enough to trigger the glitch, even if it doesn't have assignments any more:

Seems like it's something weird elsewhere in Dolphin.

I'm not familiar enough without inputcommon works to address it though.

#5 Updated by Scall almost 3 years ago

I noticed there's a loop of "PAD 0 set to mode 3" as soon as I disconnect my controller in SoulCalibur II. The lines from 348 to 489 in the attached "dolphin.log_soulcalibur_ii" are shown when the controller is disconnected. Reconnecting it immediately stops the loop (and, as you already know, triggers the glitch as well). This means the longer I wait before reconnecting it, the more consecutive "PAD 0 set to mode 3" there will be in the log.

I'm attaching a "dolphin.log_mario_kart_double_dash" as well, so you can compare the logs and see there's no such a loop in other games after I disconnect the controller.

Note: I get this "PAD 0 set to mode 3" loop with both my DualShock 4 and Xbox 360 USB controller.

#6 Updated by leoetlino almost 3 years ago

Just had an idea: can you try checking 'Always Connected'? This will make the game detect the controller as always connected (duh) even when the actual controller is unplugged. If the bug doesn't happen with that option enabled, then that means InputCommon is not to blame.

#7 Updated by Scall almost 3 years ago

Forgot the logs. Here they are.

leoetlino: sure, I'll let you know.

#9 Updated by Scall almost 3 years ago

leoetlino: yeah, when 'Always Connected' is enabled for the controller the glitch doesn't occur. Also, there's no "PAD 0 set to mode 3" loop, as you can see in the attached log.

#10 Updated by JMC4789 over 2 years ago

It seems Dolphin isn't recentering controllers that get plugged in and unplugged right then?

FYI. This is caused by our means of emulating a "Null" device when a "GCController" is chosen but the user's gamepad is not present.
We send the appropriate responses of CSIDevice_Null in this situation but we never call SetNoResponse like ChangeDeviceCallback does.
Adding this call does fix the issue but calling it directly isn't really a clean solution.

I don't know why only SoulCalibur II is affected.
