Tuxera NTFS driver with USB key

I've recently upgraded our ZCM server to version 11.2 and I've been happily testing out the new Tuxera drivers.

The only problem I'm having is trying to get the tuxura drivers to work on a USB key (The popularity of ultrabooks with our users makes USB booting a must), the tntfs module doesn't load.

I'd appreciate any insight into this problem.

Thanks

Aaron
