The USB-IF is responsible for issuing USB vendor identification numbers to product manufacturers. The cost for issuing this number is US$6,000 per year. Additionally, the use of a trademarked USB logo to identify certified devices requires a license fee of US$3,500 for a 2-year term. [6]
Common devices such as keyboards and mice send reports that are compliant with standards set by the USB Implementers Forum (USB-IF). [8] When a vendor makes a custom USB HID class device, the reports formed by the device need to match the report description given during enumeration and the driver installed on the host system.
As the standard is defined at a protocol layer, the software vendor providing the driver may be a different entity than the company designing the camera. [ 12 ] Register Access includes mandatory USB3 vision registers as well as camera specific registers which may control parameters such as shutter speed or integration time, gamma correction ...
navigator.usb.requestDevice() will prompt the user to select which USB access is to be given, or navigator.usb.getDevices() will return a list of USB devices that the origin has access to. To better search for devices, WebUSB has a number of filtering options. These filters are passed into navigator.usb.requestDevice() as a JavaScript filtering ...
The Device ID (DID) and Vendor ID (VID) registers identify the device (such as an IC), and are commonly called the PCI ID. The 16-bit vendor ID is allocated by the PCI-SIG. The 16-bit device ID is then assigned by the vendor. There is an inactive project to collect all known Vendor and Device IDs. (See the external links below.)
The vendor ID identifies the vendor of the device. The device ID identifies a specific device from that manufacturer/vendor. A PCI device has often an ID pair for the main chip of the device, and also a subsystem ID pair that identifies the vendor, which may be different from the chip manufacturer.
(USB-PD A and B plugs have a mechanical mark while Micro plugs have a resistor or capacitor attached to the ID pin indicating the cable capability.) USB-PD Devices can request higher currents and supply voltages from compliant hosts—up to 2 A at 5 V (for a power consumption of up to 10 W), and optionally up to 3 A or 5 A at either 12 V (36 W ...
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
