Problem installing USB driver

[AndyMitchell]

I have a USB driver for an Atmel micro-controller that i am tring to automatically install when the USB cable is plugged in. At the moment when the USB is plugged in it correctly finds the .inf file and ID's the device. But then it displays the 'Found New Hardware Wizard'. If i then select the 'Automatic install' it finds the driver file as specifed in the inf and installs correctly. Is there anyway to stop the found new hardware screen appearing. It already knows the correct driver and its location from the .inf. I would like it to install like a USB key, where it just goes ahead and installs the driver.

Many thanks.

After a bit of hunting around it appears that it may be that the driver is not signed. Perhaps someone can confirm this. It seems that the driver signing process is a bit of a nightmare!
