I am having a slightly weird problem relating to reading a USB device on the Mac. The device is a Amplifier so it passes audio and HID messages.
OSX 10.9.4 Using IOKit USB Debug logging library.
When plugging in and attempting to setup the USB device for reading and writing, it fails when opening the Interface with error 0xE00002D5.
I should say that this device has worked correctly on the Mac with a different ProductID. Changing the ID to any other value apart from it's original value causes the above error. Prior to this issue, the USB has worked correctly with three other devices for the past few years. If I change the ProductID back to one of the released values this works fine.
I am just a little confused about this sudden change of behavior. The USB device works well on the Windows platform.
I have traced the USB via logging enabled libraries and USB Prober, I'll include the failed log output (I'll apologize in advance for placing in question) I have removed the name of the amplifier and also the vendor and product id:

You may have guessed that I'm not a Mac expert, so any assistance would be greatly received.
Thank you.
