I sent patch "Add support of WDM drivers for USB devices." in October and
received such reply from Alexandre Julliard:

I`d like to ask about better way of modifying patches which add USB device
drivers support before doing something.
Wineusb and wineusbhub can be moved to usbhub.sys. This driver creates a
device which is used as second argument for AddDevice on Windows XP. So no
wine-specific modules will be added.
Using wineserver to call AddDevice can be avoided if move code which loads
device drivers and code which enumerates devices and call AddDevice to one
process. This can be made if use one winedevice process for all drivers. This
will allow every driver to use IRP, DEVICE_OBJECTs and other structures
created by other driver and will help to implement such functions as
IoGetDeviceObjectPointer. Can I do so? Or there are some reasons which do not
