Every once in a while driver, running latest version of programmer, Designer 5.2, will become an "unknown"
device in Vista Device Manager. If I uninstall driver, then scan for HW changes, it comes back as "unknown".
Additionally if I try to update driver by using http://www.cypress.com/?id=4&rID=30858
, Vista device manager
indicates no driver installed, but when driver file is pointed to Vista reports best driver already installed.
