POS MSR problems on WinXP

[Jeff Burton]

I'm having a problem with using Mag Stripe Readers on a Windows XP 
deployment of the OFBiz POS.  While I can observe the proper behavior 
on other platforms, on WinXP it seems the data isn't getting captured 
and waiting when paymentEvents.payCredit is run.  I can swipe a card 
in a text editor and various MSR's give the correct data, and the 
same readers work in Linux or MacOSX.

I 'm using both an ID Tech USB MSR using ID Tech's JavaPOS driver and 
a Magtek USB device with the GenericMSR driver.  When installed on 
Windows they show up as HID's and Keyboard's in the Windows Device 
Manager.  I suspect there's some setting in WinXP/Java/OFBiz I'm 
missing which allows the data to flow through to the Msr object.
