OS X 10.10 & usb4Java - Unable to claim interface: Access denied

[David Sargent]

I am trying to use usb4java (high Level interface) in OS X 10.10 environment. Things are going well until I try to claim the interface, then I get the following error:

[java] Error: javax.usb.UsbPlatformException: USB error 3: Unable to claim interface: Access denied (insufficient permissions)
[java] javax.usb.UsbPlatformException: USB error 3: Unable to claim interface: Access denied (insufficient permissions)
[java] at org.usb4java.javax.ExceptionUtils.createPlatformException(ExceptionUtils.java:39)
[java] at org.usb4java.javax.AbstractDevice.claimInterface(AbstractDevice.java:430)
[java] at org.usb4java.javax.Interface.claim(Interface.java:102)
[java] at JavaUSBTester.main(JavaUSBTester.java:236)

I have tried running the code as root, did not work either.

Is anyone currently using this in OS X 10.10 environment?
Any ideas how to correct the issue?
If I need to go to low level to make this work, will do if that is required.

Thanks

I have been running under OSX with the low level libs.
It's important to release the interface. OSX will remember
the claim over restarts of your device. It this is your issue,
rebooting OSX will allow you to do a claim it again, once.
May not be your issue, give it try
