DRIVER: DLP-USB232M

Windows arbitrarily assigns COM port numbers whenever an FTDI FT part is connected, regardless of whether or not it’s previously seen that particular individual device. The FTDI drivers do track device serial numbers to try and reassign the same port numbers, check out the Windows registry for a listing. Intermittently on powering up the system the COM port assignment of one of the boards will change. This site uses cookies to deliver our services and to show you relevant ads and job listings.
