Bug Check 0x1D4: UCMUCSI_LIVEDUMP
The UCMUCSI_LIVEDUMP live dump has a value of 0x000001D4. This indicates that the UcmUcsi class extension has encountered an error. For example this can be because a UCSI command has timed out, or because a UCSI command execution failed because the client driver returned failure.
The UcmUcsiCx.sys is the included UCSI Class Extension. For more information, see USB Type-C Connector System Software Interface (UCSI) driver.
(This code can never be used for a real bug check; it is used to identify live dumps.)
