Windows 7: USB composite device, one part fail to install

USB composite device, one part fail to install

I have a USB device, an external audio card, that installs as a four-"part" composite device, with a W7x64 installer from the device manufacturer. This has installed and worked fine on two computers. Now I've built a third one that seems to run W7x64 just fine, except... when installing the USB audio card I get a failed install on one part of the composite device. The other three parts install ok.

Does anyone have any ideas how to troubleshoot this?
Could the fact that the new computer is AMD-based (the others are Intel) have anything to do with it? Any suggestions are welcome...
