Represents a UsbDevice. Only way you can obtain one is through Context::devices https://wicg.github.io/webusb/#device-usage

Fields

configurations: Vec<UsbConfiguration>

List of configurations supported by the device. Populated from the configuration descriptor. configurations.len() SHALL be equal to the bNumConfigurations field of the device descriptor.

configuration: Option<UsbConfiguration>

Represents the currently selected configuration. One of the elements of self.configurations. None, if the device is not configured.

device_class: u8

bDeviceClass value of the device descriptor.

device_subclass: u8

bDeviceSubClass value of the device descriptor.

device_protocol: u8

bDeviceProtocol value of the device descriptor.

device_version_major: u8

The major version declared by bcdDevice field such that bcdDevice 0xJJMN represents major version JJ.

device_version_minor: u8

The minor version declared by bcdDevice field such that bcdDevice 0xJJMN represents minor version M.

device_version_subminor: u8

The subminor version declared by bcdDevice field such that bcdDevice 0xJJMN represents subminor version N.

manufacturer_name: Option<String>

Optional property of the string descriptor. Indexed by the iManufacturer field of device descriptor.

product_id: u16

idProduct field of the device descriptor.

product_name: Option<String>

Optional property of the string descriptor. Indexed by the iProduct field of device descriptor.

serial_number: Option<String>

Optional property of the string descriptor. None, if the iSerialNumber field of device descriptor is 0.

usb_version_major: u8

The major version declared by bcdUSB field such that bcdUSB 0xJJMN represents major version JJ.

usb_version_minor: u8

The minor version declared by bcdUSB field such that bcdUSB 0xJJMN represents minor version M.

usb_version_subminor: u8

The subminor version declared by bcdUSB field such that bcdUSB 0xJJMN represents subminor version N.

vendor_id: u16

idVendor field of the device descriptor. https://wicg.github.io/webusb/#vendor-id

opened: bool

If true, the underlying device handle is owned by this object.

url: Option<String>

WEBUSB_URL value of the WebUSB Platform Capability Descriptor.
