tks for your great help.
I was just assigned an project at work, an wireless remote scan device will
send remote wireless data to an local receiver(an usb device attach to SUSE
linux), the protocol being used is called Zigbee.
as u told me for the past reply, javax-usb is just transfer protocol. if so,
could you tell me how javax-usb API interact with Zigbee or other wireless
protocol? any example will be greatly appreciated.
tks in advance
john

USB is ONLY a data transfer protocol. It doesn't specify actual
device protocols. So no, I can't possibly tell you how to talk to
your specific device(s). You need to know your device protocol. You
haven't even told us what your device is.
