Win7/64 - The drivers for this device are not installed. (Code 28)

[Jay_Harbath]

My dual channel StarTech used to work just fine.
I have three older DisplayLink adapters at home that still work.
This is the second DisplayLink device I have tried to plug into this computer in a month that has utterly failed.
I'm pretty sure something is wrong with my computer, but I'll be darned if I can figure it out.

When I pull up the properties for the StarTech, it says "The drivers for this device are not installed (Code 28).
I've tried the earlier instructions in this thread to no avail.
If I need to send log files, how do I gather them?
I LOVE DisplayLink products and recommend them to all my geek friends, but I am at my wits end with this problem.
I'm on the verge of a complete reinstall of Windows 7, which I'd like to avoid.

PLEASE HELP!
