What's the problem? Describe what went wrong.

Building Dolphin with SDL enabled on Linux causes Dolphin to be unable to connect to the GameCube Controller Adapter, with the emulator declaring "Resource busy", unless the adapter is unplugged and replugged while Dolphin is running.

What steps will reproduce the problem?

1. Build Dolphin from source on Linux with default CMake settings
2. Set up GC Adapter support
3. Boot Dolphin and open Controller Configuration
4. Change Controller 1 dropdown from "Standard Controller" to "GameCube Controller Adapter (USB)"
5. Configure Port 1. Dolphin will report "Error opening device: Resource busy"

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. Repro'd on build of latest source (2412-347 at time of writing).

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

Yes, the issue is present in 2412.

If the issue isn't present in the latest release, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

As far as I can tell, this has been an issue ever since SDL input was re-added to Dolphin (5.0-16861).

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

CPU: Intel Core i7-13700k @ 5.4 Ghz
GPU: NVIDIA GeForce RTX 4060 Ti w/ 16 GiB VRAM, driver 570.124

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
