AU9540 -> AU9520 to be able to use the below readers on a Mac
Works on the following IOGear CAC reader models:
GSR202, GSR202V, & GSR203
Some IOGear CAC readers have a firmware version that will not work on a Mac (AU9540), this page will show you how to change it to AU9520, which will work on your Mac using a program called EepromMP.

2.1 Install the AU9540_V184.108.40.206 driver (from the CD in the box), then plug in the GSR202, GSR202V, or GSR203 to your Windows computer. You may also download it from: http://www.iogear.com/support/dm/driver/GSR202
2.2 Double click EepromMP.exe found at: http://militarycac.com/CACDrivers/iogear/AU9540_EEPROM.zip AU9540 reader will look like Figure 1. Click the Setting button (DO NOT insert your CAC in the reader).
