WDTF_SIMPLE_IO issue in UMDF driver RRS feed

  • Question

  • Hi,

    I have customized the sample SPBAccelerometer driver for windows7 for a customer device

    When I do HCK test for UMDF Accelerometer driver, DF - PNP (stop) rebalance device test fails with the following test log: WDTF_SIMPLE_IO : - Open(Accelerometer Device ACPI\xxxxxxx\1 ) Failed : Device is reporting a problem code (Status Flags=0x1802400 (DN_HAS_PROBLEM DN_DISABLEABLE DN_NT_ENUMERATOR DN_NT_DRIVER) Problem Code=a (CM_PROB_FAILED_START)) HRESULT=0x80004005

    Can anyone tell me how to fix it?

  • I have developed a sensor driver based on SPBAccelerometer sample for Win 8.1. This sample has good quality to pass HCK test. DF - PNP(stop) rebalance device test failure usually caused by resource allocated but not released properly. Please check that.
