If you receive the following stop error message Blue Screen :
APC_INDEX_MISMATCH

Cause of Problems :
This issue occurs because of a race condition in the Compositebus.sys driver.

When a MTP or WPD device connects to the computer for the first time, the composite bus enumerator detects the device and tries to install the WPD composite driver. During the installation process, the third-party application may run a USB device reset command. If the reset command occurs in a certain period, the race condition occurs. This certain period is after the MTP and USB driver or the MTP and IP driver is installed and before the MTP composite multiple transport driver is installed.

When the race condition occurs, the Compositebus.sys driver incorrectly releases a Windows Driver Foundation (WDF) lock when the Compositebus.sys drive does not have the lock. The APC_INDEX_MISMATCH Stop error occurs when the release function makes the asynchronous procedure call (APC) state of the current thread inconsistent.
