调研方向
Start by reproducing the issue on Fedora Linux with Sunshine's Nintendo Switch Pro emulation and compare it with the working Xbox 360 mode. Investigate the libvirtualhid UHID behavior associated with Steam's HIDAPI read failure while evdev continues receiving input. Done means the virtual Pro Controller remains available throughout a Moonlight session without repeated disconnects.

描述
Describe the Bug
When Sunshine emulates a Nintendo Switch Pro Controller via libvirtualhid on Fedora Linux, Steam and KDE repeatedly lose and rediscover the controller after a few seconds.
The virtual input device itself does not disappear from the kernel, and evdev input continues working.
Steam logs:
Controller using HIDAPI driver, vid=0x057e, pid=0x2009
Nintendo Controller subtype 3
Controller device closed after hid_read failure
Controller PollState Changed from 2 to 0
"/proc/bus/input/devices" remains unchanged during the disconnect:
N: Name="Sunshine (libvirtualhid) Nintendo Pro Controller"
P: Phys=libvirtualhid/uhid/057e:2009/7
H: Handlers=event28 js1
N: Name="Sunshine (libvirtualhid) Nintendo Pro Controller (IMU)"
P: Phys=libvirtualhid/uhid/057e:2009/7
H: Handlers=event27
"udevadm monitor --kernel --subsystem-match=input" and:
udevadm monitor --kernel --subsystem-match=hidraw
produce no add/remove events while Steam/KDE report the controller disconnecting.
Expected Behavior
The virtual Nintendo Switch Pro Controller should remain continuously available to Steam/KDE for the duration of the Moonlight session, without HIDAPI read failures or repeated disconnect/reconnect cycles.
Additional Context
"evtest /dev/input/event28" continues receiving input immediately even while Steam and KDE consider the controller disconnected.
Example:
Event: type 3 (EV_ABS), code 0 (ABS_X), value 1104
Event: type 3 (EV_ABS), code 1 (ABS_Y), value 4321
-------------- SYN_REPORT ------------
Sunshine logs creation normally:
Gamepad will be Nintendo Switch Pro controller (auto-selected by client-reported type)
Gamepad 0 will be Sunshine (libvirtualhid) Nintendo Pro Controller
Switching Sunshine's emulated controller type from Nintendo Switch Pro to Xbox 360 completely fixes the issue. Steam remains connected and input works normally.
