Function rusb::disable_device_discovery
source · pub fn disable_device_discovery() -> Result<()>
Expand description
Disable device scanning in libusb
init.
Hotplug functionality will also be deactivated.
This is a Linux only option and it must be set before any [Context
]
creation.
The option is useful in combination with [Context::open_device_with_fd()
],
which can access a device directly without prior device scanning.
