COMPortAssignment is a free utility that is used for assigning the COM Port numbers of FTDI devices. It runs under Windows XP, Vista and Windows 7. COMPortAssignment utility is available for download as a.zip file by clicking here. Here's the very minimum code required for Windows device manager to allocate the memory resource used by our PCI card. Since it's a WDM driver, it works in WinXP/2000/98. The entry point of a WDM driver is a 'DriverEntry' function (like the 'main' of a C program). Its main purpose is to publish addresses of callback functions.
is it possible for the Pnp manager not to send IRP_MJ_READ or
IRP_MJ_WRITE to a driver when user mode call ReadFile(...) or
WriteFile(...)?
i ask this because i'm having Debug messages:
PCIDEMO - Enter DispatchCreate: DeviceObject 826D33E0
PCIDEMO - Enter DispatchClose: DeviceObject 826D33E0
PCIDEMO - Exit DispatchClose
the fact that from my UserMode application i called:
HANDLE hDev = CreateFile(...);
ReadFile(hDev,..);
WriteFile(hDev,...);
In my DispatchRead() and DispatchWrite() i only have there KdPrints...
just to test if IRP_MJ_READ/WRITE was sent, could that be the reason?
IRP_MJ_WRITE to a driver when user mode call ReadFile(...) or
WriteFile(...)?
