Not sure why we had so many issues on this particular computer but at this point we are just moving on, but thanks for a reply</P> Mon, 18 Jul 2022 15:30:16 GMT https://community.nxp.com/t5/LPC-Microcontrollers/USB-Windows-Driver-Support-on-LPC55S69-when-in-ISP-mode/m-p/1491138#M49629 elemindengineer 2022-07-18T15:30:16Z
