I've got a problem with my USB Wi-Spy dbx and Chanalyser lite on mac os.

Everything worked fine, when one of my colleague used it on a chanalyser 4 on Windows.

Since that moment, the chanalyser lite stops to detect the USB Wi-Spy on my Mac, but it still working on Windows and the USB Wi-Spy works with soft like Eakiu on my Mac.
My colleague told me that there has been an upgrade of the USB Wi-Spy when he plugs the device on his laptop.

Have you ever met something like that ?
