[Bug] IR Emitter fails to trigger after system suspend/resume (Device 2b7e:b663) #246
Description
Description
I am using linux-enable-ir-emitter to configure my infrared emitter. It works perfectly after a fresh boot. However, after the system wakes up from suspend (s2idle), the IR emitter fails to turn on.
The regular webcam functionality continues to work fine after suspend (verified via sudo howdy test), but the IR emitter remains inactive. I am unsure if this is directly related to this software or a kernel/driver issue, but I have run out of ideas after trying multiple troubleshooting steps.
Hardware Information：
Device: Yilong15Pro Series GM5HG7A (Laptop)
CPU: AMD Ryzen 7 8845H
Webcam ID: 2b7e:b663 (SunplusIT Inc HD Webcam)
Sleep Mode: [s2idle] (cat /sys/power/mem_sleep)
Software Information：
OS: Arch Linux
Kernel: Linux 6.17.9-arch1-
Desktop: Niri (Wayland)
Steps to Reproduce
Boot the system (IR works).
Suspend the system (systemctl suspend).
Wake up the system.
Try to invoke the IR emitter (e.g., via Howdy or linux-enable-ir-emitter run).
IR emitter fails to turn on.
Troubleshooting Attempted
I have tried the following commands after resuming from suspend, but none of them restored the IR functionality:
Re-running configuration:
sudo -E linux-enable-ir-emitter configure
OR
linux-enable-ir-emitter run
Reloading the kernel module:
sudo modprobe -r uvcvideo
sleep 0.5
sudo modprobe uvcvideo
Resetting the USB device:
sudo usbreset "HD Webcam"
Adding Kernel/GRUB parameters:
GRUB_CMDLINE_LINUX_DEFAULT="... uvcvideo.quirks=640"
sudo sh -c 'echo 0x4 > /sys/module/uvcvideo/parameters/trace'
