Sorry for a mistake.
The code is working fine but I am facing problem if I want to change the
outData i.e. either increase the size, reduce the size or change the data.
Thanks,
Sanjay Gupta

Title : [javax-usb-devel] Hang problem with UsbPipe.syncSubmit(byte[])
Hi All,
Please look below the sample scenario:-
final byte[] outData = new byte[] {
(byte) 0x00, (byte) 0x01, (byte) 0x02, (byte) 0x03,
(byte) 0x04, (byte) 0x05, (byte) 0x06, (byte) 0x07,
(byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,
(byte) 0x08, (byte) 0x09, (byte) 0x0A, (byte) 0x01B,
(byte) 0x0C, (byte) 0x0D, (byte) 0x0E, (byte) 0x0F,
(byte) 0x00, (byte) 0x01, (byte) 0x02, (byte) 0x03,
(byte) 0x04, (byte) 0x05, (byte) 0x06, (byte) 0x07,
(byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00 }
final byte[] inData = new byte[13];
log("Synchronously submitting the byte[] to UsbPipe ...");
outUsbPipe.syncSubmit(data);
//Synchronously read the status from IN UsbPipe
log("Synchronously reading the status from IN UsbPipe ...");
inUsbPipe.syncSubmit(inData);
This code is working fine but I am facing problem if I want to change
(reduce/reduce/modify) the outData.
The control gets hang on reading the status data from the Input UsbPipe.
Any suggestion on below points will be helpful:-
1. Is there any specific data format (may be starting header) in the actual
data being transferred?
2. What is the data size which can be transferred using single invocation of
syncSubmit()?
3. What is the status data size which is received on Input Pipe as a result of
out data transfer?
Thanks in Advance..
