[Irwandi]

Dear vusb users
I interest to make java based application to control the vusb devices.
I want to connect to custom-class firmware by using java via libusbjava.
Can someone help me how to connect the vusb device by using libusbjava library?

Best regards,

, I got it

I hard worked, and tricky I got connection between my java program (modified form ReadWrite.java)
the parts of modified code are:

dev.open(1, 0, -1);
dev.controlMsg(0x40,1,value,0,data,4,5000,false);
// dev.writeInterrupt(0x81, data,data.length , 2000, false); //not yet working


// nBytes = usb_interrupt_read(handle, USB_ENDPOINT_IN | 1 , (char *)buffer, sizeof(buffer), 700000 * 1000);
//readInterrupt(int in_ep_address, byte[] data, int size, int timeout, boolean reopenOnTimeout)
for(int i=1;i<10;i++){
dev.readInterrupt(0x81, readData, readData.length, 700000*1000, false);
System.out.println("keypressed "+readData[0]+" "+readData[1]+" "+readData[2]+" "+readData[3]);

the firmware modified form CustomClass especially from custom-class. From host to device use controlmsg, while from device to host use interrupt.
I have problem to use interrupt for both.

If finish I will attach my projects in V-USB, and thank for this company for my hobby.

Best regards.
