CyUSB3.sys Device not started 0x25 CM_PROB_FAILED_DRIVER_ENTRY on Windows 7 WITHOUT UPDATES solution
few days ago have got a problem with our customized CyUSB3.sys driver - on PC with fresh Windows 7 and no updates installed our driver failed to start with this string in setupapi.dev.log :
!!! dvi: Device not started: Device has problem: 0x25: CM_PROB_FAILED_DRIVER_ENTRY.
After some investigation have found that this is because of old WDFLDR.SYS. This can be fixed by installing KB2685811 "Update for Kernel-Mode Driver Framework version 1.11 for Windows 7"
Hope this information will be helpful.
Best regards, Arturas
