  • After you configured correctly symbols, you should simply type on the command line:

    bu kernel32!DeviceIoControl

  • Problem is that all this command I've tried (bu, bp also before) but result is always "Couldn't resolve error at 'KERNEL32!DeviceIoControl'" :(

    Symbols are downloaded to folder d:\sym automatically - inside I have kernel32.pdb, ntdll.pdb, pingme.

  • You may try searching for symbol with wildcards, like
    0:007> x kernel32!*deviceio*
    76b350ef kernel32!DeviceIoControl = <no type information>
    76b11054 kernel32!_imp__NtDeviceIoControlFile = <no type information>
    or
    x *!*deviceio*
    which should do a search over all modules, (down)loading pdbs for all loaded modules.
    Diagnostic output for symbol loading you may get with
    0:007> !sym noisy
    noisy mode - symbol prompts on
    0:007> .reload /f kernel32.dll

  • bp kernelbase!DeviceIoControl should do what you need.
