How to get the imanufacturer number of USB device on windows?

As the title, I want to get iManufacturer number of a webcam, how can I do?

If I install special driver of libusb module to get iManufacturer number, I can get the number, but the webcam became a disk on my computer, and I can not use it as a camera. How can I do without installing the special driver of libusb module?

The iManufacturer number is contained in the usb device descriptor. You can get the device descriptor in user mode by using DeviceIoControl with IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX. Take a look at the usbview microsoft example, which does this in its enum code. http://code.msdn.microsoft.com/windowshardware/USBView-sample-application-e3241039
