SetupAPI.DLL to HID.DLL
- by lexdean
With the SetupAPI.DLL I execute
Function SetupDiGetClassDevs and get a pointer or handle
Then Begin a loop
Then I run
Return = Function SetupDiEnumDeviceInterfaces with SP_DEVICE_INTERFACE_DATA.cbSize = 0 to get my size of what SP_DEVICE_INTERFACE_DATA needs to be
Then I set size and execute again
SP_DEVICE_INTERFACE_DATA.cbSize = return (the size)
Function SetupDiEnumDeviceInterfaces
From the data structures I get
DevicePath from SP_DEVINFO_DATA
And a heap of information from the registry if I want it I beleave
What I’m realy wanting is to access the HID.DLL and call
HidD_GetAttributes to get VendorID, ProductID, and VersionNumber
To this Enumerated device, so I can ID the device.
I expect this particular info would come from the USB device its self.
Can any one show me how to do that.
By the way in my version of windows XP I’m using the registry path, I cannot find
HKEY_LOCAL_MACHINE\Enum\HID...\Class
I do not even get HKEY_LOCAL_MACHINE\Enum\
I think this is because I have not executed the SetupDiEnumDeviceInterfaces Function
Why?
I find Lake View Research the only data that is in complete
And does not cover this subject. Why is it all over the net when its junk????????
Thanks in advance,
J Lex Dean.
