I have a 'SABRE for Automotive Infotainment Based on the i.MX 6 Series' evaluation board.
My onboard CPU is IMX6U which is i.MX 6DualLite processor.
I have successfully built U-boot and Linux Kernel.
I am using the USB OTG port (on CPU board) to work as a USB CDC ACM serial port. On my Ubuntu 12.04, I can communicate with the target as a serial port when USB cable was connected.
However, I could not get my Windows 7 64-bit PC to work with it, Window 7 failed to find a correct driver. I googled the internet and did not find a good one for it.
Do you have a Window 7 64-bit USB CDC AMC serial driver and INF file that you can send to me? It should be a generic driver for all USB CDC ACM.
