From: francois on 27 Mar 2008 06:19 In the AddDevice() handler from our driver for USB device, we call the IoGetDeviceProperty() and it returns STATUS_OBJECT_NAME_NOT_FOUND. We use the same PhysicalDeviceObject given as a parameter in the AddDevice() handler. Can you see one possible reason for this ? Our driver is BDA driver with USB WDM lower edge. The strange thing is that problem occurs only on Windows 2000 platform with USB composite device. On Windows XP/Vista, or if the device exposes only one single USB interface, the call to IoGetDeviceProperty() is successful. Thanks for your help Francois

From: francois on 27 Mar 2008 10:52 We are trying to pull "DevicePropertyBusTypeGuid" property
From: Doron Holan [MSFT] on 27 Mar 2008 14:25 is it a multi function device and usbccgp is your parent driver? -- Please do not send e-mail directly to this alias. this alias is for newsgroup purposes only.

Yes, it is a multifunction USB device. The parent driver is usbccgp.sys on Windows XP. On Windows 2000, it should be usbhub.sys. |
