Can I install WinUSB for a USB to UART Bridge? RRS feed

  • Question

  •  My concern is that its class is Ports (Shown in Device manager->Properties->Details->Class).  Does its class HAVE to be USB to install the WinUSB.sys driver for it as described here http://msdn.microsoft.com/en-us/library/windows/hardware/ff540283(v=vs.85).aspx ?

  • you can use winusb, but then it won't look like a serial port to an app. What makes it a serial port is the driver, not the class.

    NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

  • If it is under Ports is then the system has detected it will be act as a UART.  Does the device show up with a driver, such as the system supplied one?  If it does you will need to do more to use it with WinUSB.  If it is supported do you want to do something different? 

    The device can be used with WinUSB.sys if it is connected via USB, so yes you can install it.  The question is if a driver has already recognized the device, you will need to do work to replace that driver.
