USB comport persistence across power-down
I'm using a ZedBoard with a Cypress CY7C64225 USB-UART controller, and a Windows 7 PC to control it. The USB comport appears in the Windows Device manager when I turn the ZedBoard power on, and disappears when I turn it off. I was told that the latest Cypress driver would persist the comport when power turned off so that my terminal emulation software (PuTTY or Tera Term) wouldn't sense a disconnect. This is important because I need to see what the ZedBoard sends as soon as power is turned on.
I downloaded the latest Cypress driver I could find, but Windows Device Manager thinks it is the same as the one already installed on my machine.
What should I do to fix this problem?
