I don't know the protocol of your device, so I can't tell you why it
responds the way it does...I looked briefly at your code and I have 2
suggestions:
1. in your Usbread class you should repeat the input continually, i.e.
the run() method should have a while (true) {} loop where you
syncSubmit() a UsbIrp and once it is done you repeat. Or, use a
UsbPipeListener (and resubmit the UsbIrp with that).
2. You are sending out more than just the 4 bytes. If you want to
limit the size to just the 4 bytes you want to send out, use
UsbIrp.setLength(4) or create a byte[4]. As your code is now you're
sending out extra uninitialized bytes that may confuse your device.
