I have a resource dll . It consists of an icon that I want to use for my windows driver
.First I compiled the dll for windows XP. I tried to install the driver in XP. The driver installed successfully and the icon is picked up by the device manager properly.Then I compiled the dll for Windows 7 (64 bit).I tried to install driver in windows 7.The driver was installed successfully and the device name is listed in the device manager, but there is a small blue question mark over white circle on the icon picked up by device manager . When I took the properties of the device in the device manager, it shows that the device is working properly.The problem was the blue question mark over white circle on the icon .
Please let me know the possible solutions if any one has an idea why there is a blue question mark over white circle on an icon picked up by device manager in windows 7
