Question: With JPOS driver version 1.13.3 in dual cash drawer situation what used to be cash drawer 1
appears as USB0 before it was USB1, why?
Answer: JPOS driver prior to 1.13.3 used cashed drawer USB1 to define the first cash drawer
mistakenly. With JPOS driver version 1.13.3 this was corrected to use USB0 for the first
cash drawer. One can go into “C:\HP” folder and edit the JPOS XML file manually to define
which cash drawer is the first cash drawer (will need the HID number on the bottom of the
cash drawer).
