Hi,
I want to disable my running virtual storport miniport driver using devcon.exe (devcon.exe disable …) or the device manager.
When I disable the driver right after initialization (HwStorInitialize) without doing anything else, it works fine. It works also fine after I created and reported a new virtual disk.
But when I sent a device io control code from my userspace application I cant disable the driver anymore (device manager and devcon.exe are stuck without doing anything).
My driver is not getting any message (no pnp, no adapter control code, nothing).
I have no idea how to debug this…
What I tried so far:
1)
- Install/Start driver and initialize it.
- Disable driver
- Works, no problem
- Install/Start driver and initialize it.
- Create and report new virtual disk
- Disable driver
- Works, no problem
- Install/Start driver and initialize it.
- Send a code with DeviceIoControl to my driver:
Use_decl_annotations
VOID HwStorProcessServiceRequest(
In PVOID DeviceExtension,
In PVOID Irp
)
{
// doing nothing for this test
PIRP irp;
irp = (PIRP)Irp;
irp->IoStatus.Status = STATUS_SUCCESS;
irp->IoStatus.Information = 0;
IoCompleteRequest(irp, IO_NO_INCREMENT);
} - Close the userspace application to close the opened handle
- Disable driver
- devcon and device manager stuck without notifying my driver about anythig.
I have no idea how to debug this…
Thank you…
