Hello, I have a board using the Keil Middleware USB device software. The included driver is mcb1800-vcom.inf DriverVer=05/13/2013,5.3.0.0 Is there a newer version available that is signed? I'm using Windows 7 Embedded, and none of the usual workarounds have worked to get around having an unsigned driver, I have to press F8 at every boot. Thanks!
Hello Matthew,
Our .inf file makes calls to the USBSER.sys file. Perhaps your version of that file is out of date or missing? This appears to be an issue many Windows 7 Embedded users face:

Having a modern version of usbser.sys may allow you to install the driver.
