Examples of Usb_Device_Descriptor

ch.ntb.inf.libusbJava.Usb_Device_Descriptor
Represents the descriptor of a USB device.
A USB device can only have one device descriptor. It specifies some basic, yet important information about the device.

The length of the device descriptor is {@link ch.ntb.inf.libusbJava.Usb_Descriptor#USB_DT_DEVICE_SIZE} and the type is{@link ch.ntb.inf.libusbJava.Usb_Descriptor#USB_DT_DEVICE}.
