Dan
Cheers for that, that has now enabled me to get my usb radio to switch on. The
Snoopy log I posted was the wrong message, not sure what that one does, but for
information, the snoopy log that turned on the radio was:-
00000027 0.00464249 UsbSnoop - IRP_MJ_CREATE

00000053 0.00961938 UsbSnoop - IRP_MJ_CLOSE
I achieved this by doing the following:-
byte bmRequestType = (byte)0xc0;
byte bRequest = 0x02;
short wValue = 0x01;
short wIndex = 0x00;
byte[] buffer = new byte[8];
UsbControlIrp usbControlIrp = usbDevice.createUsbControlIrp(
bmRequestType, bRequest, wValue, wIndex);
usbControlIrp.setData(buffer);
try {
usbDevice.syncSubmit(usbControlIrp);
} catch ( UsbException e ) {
logger.error("DCP submission failed : " + e.getMessage());
}
Thanks again......
