Hi Dan and thank you for your answer.
To make my request more comprehensive, I'm trying to drive a CM15 module
which is a X10 controller for home automation (domotic) with Java. Here is
the component :
http://www.automatedhome.co.uk/New-Products/X10-CM15-Pro-Review.html
Thanks to that stuff, I'm trying to light on and light off X10 module AM12 (
http://www.reallycleverhomes.co.uk/acatalog/Marmitek_AM12_X10_plug_in_appliance_module.html)
and I need to give orders by my CM15.
I have installed driver for CM15 on my debian system using this generic USB
: http://www.linuxha.com/USB/
My CM15 is well detected by the system.
In my test class, I detected this material with this code :
UsbHub virtualRootUsbHub = ShowTopology.getVirtualRootUsbHub();
List allUsbDevices = FindUsbDevice.getAllUsbDevices(virtualRootUsbHub);
List usbHubs = FindUsbDevice.getUsbDevicesWithDeviceClass(virtualRootUsbHub,
UsbConst.HUB_CLASSCODE);
System.out.println("Found " + allUsbDevices.size() + " devices total.");
System.out.println("Found " + usbHubs.size() + " hubs.");
allUsbDevices.removeAll(usbHubs);
UsbDevice usbDev = (UsbDevice) allUsbDevices.get(0);
udbDev in this code corresponds correctly at my CM15 component.
I have used this script perl example to verify that all is well configured :
use Fcntl;
sysopen( CM15A, "/dev/cm15a0", O_RDWR |O_NOCTTY | O_NONBLOCK ) || die
"Cannot open device $!";
syswrite CM15A, pack( "CC", 4, 0x61 ), 2;
sleep 1; # can be less
syswrite CM15A, pack( "CC", 6, 0x62 ), 2; # ON
#syswrite CM15A, pack( "CC", 6, 0x63 ), 2; # OFF
close( CM15A );
When I try this example, I can light on and off my lamp without a problem.
I'm trying to do the same in Java with javax.usb.
As I write in my previous mail, here is my code :
byte bmRequestType =
UsbConst.REQUESTTYPE_DIRECTION_IN |
UsbConst.REQUESTTYPE_TYPE_STANDARD | UsbConst.REQUESTTYPE_RECIPIENT_DEVICE;
byte bRequest = UsbConst.REQUEST_GET_CONFIGURATION;
short wValue = 0;
short wIndex = 0;
byte[] buffer = new byte[256];
buffer[0] = (byte) 0x62;
UsbControlIrp usbControlIrp =
usbDev.createUsbControlIrp(bmRequestType, bRequest, wValue, wIndex);
usbControlIrp.setData(buffer);
usbDev.syncSubmit(usbControlIrp);
I reuse code I see in examples on SourceForge but this doesn't work...
I'm not sure because I'm not familiar at all with javax.usb but my
bmRequestType and/or my bRequest mustn't be well declared.
Concretly, I need to send this data : 0x62 to my USB component...
What is wrong in my code?
Thanks again for your help!
