A client is unable to install the USB CDC driver on Windows 7 Embedded. They were previously able to install it on Windows XP embedded. We used the usb_dev_serial.inf with modifications for the correct PID and VID as well as strings. The error they're receiving is the following:
Windows found driver software for your device but encountered an error while attempting to install it.
Driver is not intended for this platform.
Any help is greatly appreciated.
