I have some card-swipe reader code in experimental stages that was loosely based on the MouseDriver example. I have been running into a problem, though. It seems that if a device is claimed, released, and then re-claimed in the same process, the second claim fails with this error:
Could not claim interface to drive HID device: Could not claim interface : Device removed (or no such device) (error number -19) I was able to make a very simple modification to the MouseDriver program to make this fail... if I simply enclose the whole program in a loop (so the device is unclaimed when "Enter" is pressed and then re-claimed when the loop starts again), and take out the checks that ensure it is a mouse (because I'm not using a mouse in this particular application), it will have the same problem. I can work around this by passing a UsbInterfacePolicy with forceClaim() always returning true and it works fine. However, I am not sure if this is the correct way to do this. Any info would be helpful. A final note, I'm using these versions: javax-usb : 0.10.2 javax-usb-ri : 0.10.2 javax-usb-ri-linux : 0.10.5 Apparently there are new versions in the works, should I just upgrade to whatever is in source control now? OR will there be an "official" release soon?
