I need help with supporting a particular USB device under wine. I have to start by saying that although I am an experienced C/C++ programmer with some Linux experience, I have almost no Windows or wine experience.
The Windows code for which I need to provide support uses CreateFile() to get a handle to the device. The name of the device is something like "\\.\MyDevice0" "\\.\MyDevice1" and so on. Then, the code uses DeviceIoControl() to read and write from/to the device. The requirement is not to change the windows code.
I looked through the wine code and I found this in device.c:
static const struct VxDInfo VxDList[]
I could add another entry into the table and write a deviceio handler (BOOL (*deviceio)(DWORD, LPVOID, DWORD, LPVOID, DWORD, LPDWORD, LPOVERLAPPED);). I wrote some test code in Linux using libusb reading and writing to the device so I know what to do inside the deviceio handler.
Is this the right approach? If so, what do I need to do to get CreateFile to return the right handle?
Or should I write an external driver that gets loaded by wine? If so, how would I do that? What are the chances that the Windows driver for this device would just work with wine?
Thanks,
