It sounds like there is already a driver driving your device (in the 2.6 kernel at least). In the file /proc/bus/usb/devices, if you find your device, does the I: line say that it has a driver? If so, you need to remove the driver if you want to drive it via javax.usb. If you use the UsbInterfacePolicy with the forceClaim() option set to true, you can kick the existing driver off and drive it yourself. You need a kernel version 2.4.23 or later (including 2.6).
