I am connecting a ZED board to HP laptop , Windows 7 enterprise OS. I installed the CypressDriveInstaller_1. When I connect both the USB ports on the ZED board to the PC (J17 - PROG & UART) , "USB to UART Adapter" does not show up in the device list. If connect just the UART only (and not the programming cable), I still do not see anything in the device tree. When I connect the programming cable, it shows up as "USB serial Converter" in the device tree and as "COM3" in the COM & LPT ports list. Only COM3 shows up in that list. No other com port. If I open the serial port terminal (Teraterm) , it won't let me program (Vivado cannot open the hardware). After I kill the serial port I can program and when I open the Teraterm and connect to COM3, I get a message "Cannot open COM3". If I right click on COM3 in the device tree and look at the driver details, it shows the driver as "FTDI driver". This is happening on 2 HP computers ( a desktop and a laptop). The board works fine with the serial port on a Dell laptop with windows 7 professional. I would appreciate any help to resolve the problem.
Thanks,
Mohan
