Merging devices in Windows 7 Devices and Printers

My company makes a product that includes both a display and a USB input device. Right now they show up as two separat开发者_开发百科e icons in Devices and Printers, and we'd obviously like them to be exposed as one.

According to the documentation at MSDN, the way to do this is to provide a ContainerID through one means or another, but display devices are not mentioned at all. Does anyone have an idea how to manage the ContainerID of a display device?

fix. but it's aesthetic anyway, if you right-click the printer and hover over properties, you can choose props for each individual printer, and they're seperately selectable in printer choice drop-downs, such as in word > file/ribbon > Print [choose either & go].

But either way, if you're after a fix, the link is above.
