getUsbDevices
Instantiates a list ofUsbDevice
objects, representing devices connected via a usb port (including internal devices).If the value of
tree
is true, the top level devices returned from this method are the USB Controllers; connected hubs and devices in its device tree share that controller's bandwidth. If the value oftree
is false, USB devices (not controllers) are listed in a single flat list.- Parameters:
tree
- If true, returns a list of controllers, which requires recursive iteration of connected devices. If false, returns a flat list of devices excluding controllers.- Returns:
- a list of
UsbDevice
objects.
