Remarks
A class representing USB request packet. This can be used for both reading and writing data to or from a android.hardware.usb.UsbDeviceConnection. UsbRequests can be used to transfer data on bulk and interrupt endpoints. Requests on bulk endpoints can be sent synchronously via UsbDeviceConnection#bulkTransfer or asynchronously via #queue and UsbDeviceConnection#requestWait. Requests on interrupt endpoints are only send and received asynchronously.
Requests on endpoint zero are not supported by this class; use UsbDeviceConnection#controlTransfer for endpoint zero requests instead.
