CyUsb.sys driver failure

Question: CyUSB.sys driver fails with the screen dump message: DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS. What is the solution for this?

 

Answer:

 

The DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS bug check has a value of 0x000000CB. This indicates that a driver or the I/O manager failed to release locked pages after an I/O operation. This error message usually appears if the registry value \\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\TrackLockedPages is equal to DWORD 1. More information can be found on Microsoft website at the following link: DRIVER_LEFT_LOCKED_PAGES_IN_PROCESS.

  

Please use the updated driver available through SuiteUSB SDK which does not have this bug.
