Q1 : What you mean is you are confused at the set or get data by ways of
the Report_ID via USB. Java and Linux have nothing to do with it.
A1 : Because I never succesfully get the response(data) so i confused a lot.
Q2 : Did you claim the interface? And specifically what endpoint are you
tring to get?
A2 : Yes, I have claimed that interface and it only has only one endpoint
(In-Endpoint)
===================================================================================
1. I could get the data(115) by the ReportID(29) in Windows.
2. In fact, i am so dubitable about the parameter to that 4 parameters
(UsbControlIrp)
3. Please give me any advise, direction, or correct if you have any doubts.
4. Below are my code and Thank your reading
===================================================================================
class PacketAPP extends Thread{
public static UsbEndpoint endpoint = null;
public PacketAPP(UsbEndpoint endpoint){
this.endpoint = endpoint;
}
public void run(){
try{
UsbPipe pipe = endpoint.getUsbPipe();
byte bmRequestType = (byte)0xA1;
byte bRequest = UsbConst.REQUEST_SET_FEATURE;
short wValue = 0x1D03;
short wIndex = 0;
UsbControlIrp irp = pipe.createUsbControlIrp(bmRequestType,
bRequest, wValue, wIndex);
byte data[] = new byte[3];
irp.setData(data);
pipe.open();
while(true){
pipe.syncSubmit(irp);
irp.waitUntilComplete();
for(int i=0; i<data.length; i++){
System.out.print(data[i]+" ");
}
irp.setComplete(false);
sleep(1000);
}
}
catch(UsbException e1){
System.err.println("Exception : Class ReceivePacketAPP : run() : e1 : " +
e1);
}
catch(Exception e3){
System.err.println("Exception : Class ReceivePacketAPP : run() : e3 : "
+ e3);
}
}}
