Xenith lpt ports not mapping after firmware 2.0 upgrade

Xenith lpt ports not mapping after firmware 2.0 upgrade

Using Xenith Pro (Rx0L) under firmware 1_7_122 the local usb receipt printer was automatically mapped to lpt1 using xenapp 6.5. Apps could print directly to lpt1 and everyone was happy.

After ugrading the Wyse to firmware 2_0_015, the lpt ports are no longer mapped. What's changed? Dropped back down to 1_7_122 and all working fine again.
