Finding USB serial ports from a .NET application under Windows 7
问题 I have an application that looks for a specific FTDI serial port with customised USB descriptors. My current code uses the example from Code Project, which searches the MSSerial_PortName WMI table under root\WMI , and pulls out extra USB information from root\CIMV2\WIN32_PnPEntity . This worked well under XP, but the application must also run under a standard user onWindows 7. In this environment access of root\WMI results in an "Access Denied" ManagementException . Can anybody suggest a way
