Author: vmikayelyan Date: Fri Aug 19 16:29:16 2016 New Revision: 72382 URL: http://svn.reactos.org/svn/reactos?rev=72382&view=rev Log: usb: hub: FDO: Removed dublicated functions and fields FDO_QueryInterface() is unuseful beacuse we have more generic QueryInterface() function which is able to replace all functionality which provides FDO_QueryInterface(). Also we do not need to have two "USB_BUS_INTERFACE_USBDI_V2" fields in "HUB_DEVICE_EXTENSION". FDO_QueryInterface() was added in svn-rev 55983, and on review of that commit I have found some copypasta issues and also tricks which was not documented and marked by me as wrong. For example changing if buscontext which was fixed in previous commits of this commit set.

Author: vmikayelyan Date: Fri Aug 19 16:22:18 2016 New Revision: 72379 URL: http://svn.reactos.org/svn/reactos?rev=72379&view=rev Log: usb: hub: FDO: Fix CreateUsbChildDeviceObject() There were code dublication on copy device interface, also after copying interface, we should call InterfaceReference() routine of interface, to prevent interface provider deleiton. I have moved RtlCopyMemory() and InterfaceReference() to the end of this function to siplify cleanup part, because otherwise we should call InterfaceDereference() in cleanup part. The changing of interface context seems wrong for me, let me give just one example. When we are changing only buscontext, then when upper layer calls interfaceDereference(), which is "thinking" that works with it's buscontext, and tries to work with it using it's buscontext pointer. So changing of buscontext is completely wrong.
