What happened?

This appears closely related to #927.

Unlike the original report, I reproduced the issue with VirtualBox 7.2.22 and different USB devices. Disabling VBoxUSBMon prevents reproduction so far.

WinDbg_VBox_7.2.22.txt

The Windows host reproducibly crashes during USB hot-plug with:

PNP_DETECTED_FATAL_ERROR (0xCA), Arg1 0x2 (Invalid PDO)

The crashes occurred when connecting different USB devices (USB-UART and USB-Ethernet) through a Lenovo ThinkVision USB hub / Lenovo docking station.

WinDbg reports:

IMAGE_NAME: VBoxUSBMon.sys
SYMBOL_NAME: VBoxUSBMon+3dc3
FAILURE_BUCKET_ID: 0xCA_2_VBoxUSBMon!unknown_function

Relevant stack:

nt!KeBugCheckEx
nt!IoGetDevicePropertyData+0x9b
VBoxUSBMon+0x3dc3

The affected device object belongs to:

\Driver\USBHUB3

The same failure was previously reproduced with VirtualBox 7.2.14. Updating to 7.2.22 did not resolve it.

As an A/B test, I disabled VBoxUSBMon and rebooted. I then repeatedly connected and disconnected the same USB devices through the ThinkVision USB hub and docking station without another crash.

Expected behavior: USB hot-plug on the Windows host must not cause a host OS bugcheck, regardless of whether VirtualBox is running.

How can we reproduce this?

1. Run VirtualBox 7.2.22 on a Windows 11 Enterprise 24H2 host, Build 26100.x.
2. Ensure VBoxUSBMon is enabled and running.
3. Connect the host through a docking station / monitor with an integrated USB hub.
4. Start a VirtualBox VM.
5. Hot-plug a USB device, e.g. USB-Ethernet or USB-UART, into the downstream USB hub.
6. The Windows host may crash with PNP_DETECTED_FATAL_ERROR (0xCA), Arg1 0x2.
7. WinDbg !analyze -v identifies VBoxUSBMon.sys.

Workaround / A/B test:

sc.exe config VBoxUSBMon start= disabled

After rebooting, VBoxUSBMon reports Stopped / Disabled. The same USB hot-plug operations have not reproduced the crash so far.

Re-enabling VBoxUSBMon is therefore currently avoided.
