SetupDiOpenDeviceInfo - adding devices based on wildcard chars
in [Device Drivers]
|
From: JY on 3 Mar 2010 08:49 Hi, I'm trying to add device instances to a DeviceInfoSet using SetupDiOpenDeviceInfo(), but the DeviceInstanceId parameter is not accepting any wildcard characters in it. For example, I want to add all device instances with "USB\\MyVendorID\\*" or "USB\\MyVendorID\\0000" if 0000 could match anything perhaps, but the call fails with ERROR_NO_SUCH_DEVINST. My question is, how do I add all devices belonging to the logical group "USB\\MyVendorID" to the DeviceInfoSet? TIA, JY
