Determining your firmware version in Windows
To determine the firmware version of the auxiliary processor using a Windows computer:
1. Connect the Orangutan SVP to your computer via USB.
2. Open up the Device Manager.
3. Double click on the “Pololu Orangutan SVP Programmer” entry in the “Ports (COM & LPT)” list.
4. In the Details tab, select the “Hardware Ids” property in the dropdown box.
5. The first value displayed should be something like USB\VID_1FFB&PID_0087&REV_0101&MI_00 . The
number after the REV_ is your revision code. You can determine your firmware version by inserting a decimal
point after the second character of your revision code. If the revision code is “0100” then you have firmware
version 1.00. If the revision code is “0101” then you have firmware version 1.01.
