Revision history for Device-USB

0.21    2007/04/16
        Thanks to Vadim Mikhailov for spotting a problem with use of the macro
        Inline_Stack_Vars that prevented compilation under Windows. Applied
        Vadim's patch.
0.20    2006/11/18
        Added support for interface objects and corrected the code
        returning the code. Previous versions had only returned the first
        setting of the interface.
        Deprecate the Device::USB::Device::config method as badly named and
        incomplete. Replaced with Device::USB::Device::configurations and
        Device::USB::Device::get_configuration.
0.19    2006/09/18
        Modified Inline::C code to be correct C. (reported by Craig DeForest.)
        Changes Device::USB::Device interface to automatically open the
        USB device if needed, as requested by Ray Brinzer.
0.18    2006/09/17
        Added CLASS_* constants to the Device::USB module.
        Added class support for the configuration objects.
        Try again to fix assumption in tests, this time found by Ray Brinzer.
0.17    2006/09/04
        Added FAQ document. Added new Device::USB::list_devices_if() and
        Device::USB::find_device_if() methods for more flexible device
        searching. Minor documentation cleanup.
0.16    2006/09/01
        Modified Device::USB::list_devices() to support listing all devices.
        Thanks to Tony Awtrey for pointing this out. He also spotted an
        invalid assumption in the tests; that has been corrected.
0.15    2006/08/08
        Applied patch from Mike McCauley that adds
        Device::USB::Device::get_driver_np() and
        Device::USB::Device::detach_kernel_driver_np() methods, as well as
        extending the debugging modes.
0.14    2006/07/10
        Corrected the bInterfaceClass field in the interface
        descriptor. Thanks to Josep Monés Teixidor for spotting it.
