New Revision: 54791

URL: http://svn.reactos.org/svn/reactos?rev=54791&view=rev
Log:
[USB-BRINGUP]
- Implement HidClassFDO_DeviceRelations
- Implement IOCTL_HID_GET_COLLECTION_INFORMATION,  IOCTL_HID_GET_COLLECTION_DESCRIPTOR
- Implement IRP_MN_QUERY_ID, IRP_MN_QUERY_CAPABILITIES, IRP_MN_QUERY_BUS_INFORMATION,
IRP_MN_QUERY_PNP_STATE, IRP_MN_QUERY_DEVICE_RELATIONS, 
- HIDClass PDO is now created and starts initialization, needs IRP_MN_START_DEVICE request
implementation
- Tested in Vbox 4.1.4 + WinXP + ReactOS hidusb,hidmou,hidclass
