I'm looking for a way to see if a driver is installed on a PC

Question

Hi All I'm looking for a way to see if a driver is installed on a PC it is for a USB to serial converter The problem is I want to check to see if there is a driver for it installed. At the moment I have the code ServiceController[] scDevices = ServiceController.GetDevices(); foreach (ServiceController scTemp in scDevices) lstDrivers.Items.Add(scTemp.ServiceType +  + scTemp.ServiceName +  + scTemp.DisplayName); This appears to list several files that could be the driver I am looking for...

You can get more information about a driver using WMI and in particular the Win32_PnPSignedDriver class. http://msdn.microsoft.com/en-us/library/windows/desktop/aa394354(v=vs.85).aspx Here's some code to list the properties and their values for each driver. You'll need to add a reference to System.Management.dll to your project if it's not been added already: using System; using System.Management; class Test { static void Main() { ManagementObjectSearcher searcher = new ManagementObjectSearcher(SELECT * FROM Win32_PnPSignedDriver); foreach (ManagementObject obj in searcher.Get()) { foreach(PropertyData prop in obj.Properties) { Console.WriteLine({0} : {1} prop.Name prop.Value); } Console.WriteLine(
Press any key to view info for next driver); Console.ReadKey(); Console.WriteLine(); } } }

Forgot I asked that(!) the problem is I have at least drivers it could be and I think the device uses a standard FTDI driver that I don't want to uninstall as I have several non-related bits O' hardware attached...

Seems similar to your previous problem in detecting whether a driver was installed or not (link below). Are you saying this time that you're not in a position to install the driver you just want to know whether it's installed already? http://www.c-sharpcorner.com/forums/thread/177238/checking-for-a-usb-to-com-port-driver-using-C-Sharp.aspx
