To use the CyControl software to access the second device, you need to bind this to Cypress's cyusb3.sys driver.
Double click the unknown device in the device manager, in the properties window, go to Drivers Tab. Click Update Driver -> Browse My computer for Driver Software -> Let me pick from a list of device drivers on my computer -> Have Disk -> Browse and select the INF file "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\driver\bin\win7\x64\cyusb3.inf"
Select any one of the devices say "Cypress USB Bulkloop Example" and finish the driver binding process. You can find the device on CyControl Software,
