deviceiocontrol returns error 1

NTDEV
1

I am using an out of the box Umdf driver, testapp.c as for the code and the osrusbfx2 board for the c# host interface. The device is recognized and I get a valid path and get the handle in file create. I get an error code 1, Invalid function when I execute FileIO.DeviceIoControl

Import the dll methods:
[DllImport(“kernel32.dll”, SetLastError = true, CharSet = CharSet.Auto)]
internal static extern IntPtr CreateFile(string lpFileName, uint dwDesiredAccess, uint dwShareMode, IntPtr lpSecurityAttributes, uint dwCreationDisposition, uint dwFlagsAndAttributes, IntPtr hTemplateFile);
[DllImport(“kernel32.dll”, ExactSpelling = true, SetLastError = true, CharSet = CharSet.Auto)]
internal static extern bool DeviceIoControl(IntPtr hDevice, uint dwIoControlCode,IntPtr lpInBuffer, uint nInBufferSize,IntPtr lpOutBuffer, uint nOutBufferSize,out uint lpBytesReturned, IntPtr lpOverlapped);

The actual calls:
IntPtr pDeviceHandle = FileIO.CreateFile
(myDevInfo.myDevicePathName,
(FileIO.GENERIC_WRITE | FileIO.GENERIC_READ),
FileIO.FILE_SHARE_READ | FileIO.FILE_SHARE_WRITE,
IntPtr.Zero,
FileIO.OPEN_EXISTING,
FileIO.FILE_ATTRIBUTE_NORMAL | FileIO.FILE_FLAG_OVERLAPPED,
IntPtr.Zero);

// IOCTL_OSRUSBFX2_GET_CONFIG_DESCRIPTOR
success = FileIO.DeviceIoControl
(pDeviceHandle,
CTL_CODE(0x65500, 0x800, 0, 0X80000000),
pBuffer,
size,
pBuffer,
size,
out nBytes,
IntPtr.Zero);

What am I doing wrong?

Did you define CTL_CODE somewhere? How are you pinning the buffers?

Most likely your IOCTL’s Access parameter (see CTL_CODE macro and
IOCTL_OSRUSBFX2_GET_CONFIG_DESCRIPTOR definition) has invalid value.
In your code you specify 0x80000000 which is definitely not the same
as FILE_READ_ACCESS value defined as 1.
Btw. you should share declarations of common data structures or
defined constants between app and drv whenever is possible to avoid
such mistakes.

I don’t know where I got the 0x80000000 and it was a very long day, but I changed the FILE_READ_ACCESS value to 1, and I got 39 bytes of data!!! And I will share declarations!!!

My hats off to you as the best there is!!!

For one thing, you opened the file with FILE_FLAG_OVERLAPPED, but you
did not supply an OVERLAPPED structure in the DeviceIoControl call.
When you open a file in overlapped mode, EVERY I/O request must be done
with an OVERLAPPED structure. It doesn’t crash (at least not every
time), but that violates the contract.
