I tried this on my 2013 Macbook pro retina, but usb.generic.allowHID = "TRUE" is not in the list of possibilities to edit per this link
HowTo: Setting up VMware Fusion to work with HID devices
I have done this in the past with my 2010 macbook pro so i wonder if having a usb3.0 machine is part of the issue. here is the list of things i can edit. Any help would be greatly appreciated. I have Mavericks running on the MAC, Fusion 6.0.4 (1887983), and Windows 7
