Problem When Shutting Games Down (w/ Bluetooth Passthrough)

[awosaibi]

Hello everyone!


First, let me say that I have WinUSB installed and it works great when I have a game up and running. There is only one small issue...

After I close a game and try to start another, I get an endless black screen. The problem goes away when I restart Dolphin and start a game, but persists when I try to launch any subsequent titles.
I also found out that after closing a game down (using the stop button), I get abnormally high CPU usage for Dolphin:

Whenever I launch a game while it's in this state and with Bluetooth Passthrough enabled, I get the black screen.

It also spits this out in the logs:

Code:

01:50:855 core\ios\stm\stm.cpp:48 I[IOS_STM]:     IOCTL_STM_VIDIMMING
01:50:871 core\ios\ios.cpp:475 I[IOS]: Opening /dev/usb/oh1/57e/305 (mode 0, fd 6)
01:50:881 core\ios\usb\bluetooth\btreal.cpp:89 E[IOS_WIIMOTE]: Failed to get config descriptor for device 8086:a12f
01:50:881 core\ios\usb\bluetooth\btreal.cpp:106 N[IOS_WIIMOTE]: Using device 8087:0aa7 (rev 1) for Bluetooth:  
01:51:448 c:\buildbot\release-win-x64\build\externals\cubeb\src\cubeb_wasapi.cpp:377 N[Audio]: Audio device property value changed.

and nothing after that.
It seems to correctly identify and select the Bluetooth device, I'm just not sure what the 3rd line Failed to get config descriptor for device 8086:a12f means.

Obviously, this is a Bluetooth Passthrough related issue, as when I use Emulated and close a game down, I don't get the same high CPU usage.
Could it be stuck in some sort of loop...? I'm currently using version 5.0-10551.


Any help is highly appreciated. Thanks!

This seems to be a known issue for WinUSB. Try switching to libusbk.
EDIT: This may be inaccurate, see below. Sorry! Keeping an eye on the thread themanuel linked may be your best bet for now.

It is not just WinUSB, it happens with libusbK as well, but not to everyone.
