WebUSB: Add exclusionFilters to USBRequestDeviceOptions
Browse files Browse the repository at this point in the history
This CL adds a new "exclusionFilters" option in
navigator.usb.requestDevice() options so that web developers can
exclude from the browser picker some devices that are known to not work
as expected.
