USB HID Problem - Works in Windows but not MAC OSX or LINUX

I am having some problems with an HID Device that I have created. I have been battling this for a few months now, trying nearly everything that I can think of.

It works fine in Windows. However, it fails to connect to Mac OSX or Linux. Even if I dual boot my machine, it will work fine in Windows and fail to load the device in Linux. This leads me to strongly believe that it is a software issue. The error in the linux syslog is "Device Descriptor read/8 error -75" I have not been able to track down this error message relating to a particular problem.

The device is a fairly straight forward extension of the USB Mouse. It is simply a USB Mouse and a gamepad.

Rather than paste the code here, I have posted it on my website: www.zero-soft.com/CCS_Code/

I really think that the problem is somewhere in the descriptor, but I can't track it down for the life of me.

I would greatly appreciate any help/advice/feedback/thoughts.

Sincerely,
Drew

I tried my CDC device on the Mac and it found it as a serial port. and I spoke to it using the Screen command in the terminal. This was a work Mac but I will be hopefully getting one soon, I hope you have success with your project and please post if you have success.
