This article explains the different ways your Point Grey USB 3.0 camera may appear in the Windows Device Manager.
The way that Point Grey USB 3.0 cameras appear in the Windows Device Manager depends on the driver configuration that is currently in use. In general, there are two ways to run a Point Grey USB 3.0 device:
- Install the Point Grey PGRxHCI (pgrxhci.sys) driver on a USB 3.0 xHCI card or built-in port. Although not the default installation configuration, this configuration is recommended, unless specified otherwise in TAN 10359. In this configuration, the USB 3.0 xHCI card or built-in port appears under the 'Point Grey Bus Host Controllers' node in Device Manager. The camera does not appear. This is shown as (A) in the figure below.
Note: The PGRxHCI driver may be incompatible with other (non-Point Grey) USB 3.0 devices that run on the same bus.
- Use the driver provided by the manufacturer of the USB 3.0 xHCI card or built-in port. In this scenario, the Point Grey PGRUSBCam (pgrusbcam.sys) driver on the camera works in conjunction with the USB 3.0 driver installed on the card. The camera appears under the 'Point Grey Research Devices' node in Device Manager, and the xHCI card or built-in port appears under the 'Universal Serial Bus controllers' node. (There is no easy way to differentiate between a card that is installed separately and a built-in port.). This scenario is the default configuration when Point Grey USB 3.0 drivers are installed during the setup process for your USB 3.0 device. This is shown as (B) in the figure below.
