miniHID driver with my own GUID ?
in [Device Drivers]
|
From: joshuachuang on 28 Jan 2010 06:20 Hi, I try to create my own GUID in Elo-Pen Driver sample by using WdfDeviceCreateDeviceInterface(). But when I use that GUID to try to CreateFile, system always return error code 31. Which means the driver is not functional ... but the driver is still alive and I could use it as a mouse ... What's going wrong? Joshua
