Xenith Pro USB support

Xenith Pro USB support

I am trying to configure USB support in my Windows 7 VM using the Xenith Pro. I was able to do this very easily before I managed the device with the xen.ini file but now that i have configured it to pull the config from the ini file the USB support for flash drives does not seem to work. I have tried the following in the ini file and it does not appear to work.

SessionConfig=All \
DefaultColor=2 \
MapDisks=Yes \
vusb_disks=yes

I am looking for the USB drive to show up under the Win 7 explorer to allow read/write access which I was getting before I started to manage the device with the ini file.
