Problem
I am experiencing a repeatable issue on my main PC where the Pimax Crystal Light headset's tracking fails to initialize unless I manually disable and then re-enable the camera device in Windows Device Manager.
Actual Behavior
* The Pimax Crystal Light headset is detected normally by the system.
* Tracking is completely non-functional upon initial connection or system boot.
* Manually disabling and then re-enabling the camera device in Windows Device Manager immediately resolves the tracking issue.
* This behavior occurs consistently with every system boot or headset reconnection.
Expected Behavior / Comparison
* The same Pimax Crystal Light headset and its associated cables function perfectly, with immediate tracking initialization, when connected to a second PC.
What I Have Tried
* Tested different USB ports and USB controllers (direct to motherboard, no external hub used).
* Disabled all USB power management settings.
* Removed all "phantom" or hidden devices from Device Manager.
* Performed a clean reinstallation of the Pimax runtime software.
* Performed a clean reinstallation of AMD chipset drivers.
* Verified that both the problematic main PC and the working second PC are running the same Windows version and utilize the identical usbvideo.sys driver.
Extra Details

My main system is heavily configured with multiple USB and PCIe devices, including a capture card. I suspect this issue may be related to timing during USB/UVC initialization or a conflict within the Windows camera stack.
I am not seeking basic troubleshooting steps, as I have already performed extensive testing. I am specifically trying to understand why the camera endpoint fails to initialize properly on this particular system only.
If you have experience debugging complex USB, UVC, or VR device initialization issues, I would greatly appreciate any insights or direction you can provide.
