USB-8473s Bus Monitor Won't Start

Question

Hello
I have an 8473s USB CAN module I am trying to get working.
I have MAX 5.5 and CAN 2.7.5 on Windows 7
The 8473s sometimes starts with a nice yellow USB light, sometimes with one that flashes green-yellow, sometimes one that flashes in a pattern yellow two short two long (I think, it's been a while since this one happened and I didn't take good notes on the pattern)
I can expand Devices and Interfaces, and then NI-CAN Devices, and then USB-8473s. Then in the right pane I click on Bus Monitor. And that's the last thing I can do before I have to task kill MAX.
Sometimes I am able to Self Test the unit, sometimes not. Bus Monitor used to take a long time then pop up a confusing message: "NI-CAN: (Hex 0xBFF62103) The firmware of the CAN or LIN hardware no longer responds to commands from the Windows driver, usually due to frequent CAN/LIN or timer interrupts. Solution: For CAN, use comparator/mask (filter) properties to reduce received trafic." After that the Bus Monitor would show it's user interface, but if I tried to Start, it would go Not Responding and never come back (or at least not after a half an hour).
I have two 8473s units, and both respond the same. I have tried different USB ports with no difference. I have tried to repair the CAN 2.7.5 driver, and it did not help.
What else should I do to get Bus Monitor to work?
I wish I had a PCI CAN interface. I don't trust the USB.
Thanks
Keith

Thanks for the input.
The machine that is the subject of the original post is the customer equipment. It is an Advantech industrial PC.
I tried it on my development system, a Lenovo Laptop, and it works perfectly.
My current best guess is an incompatibility with the Advantech, some kind of motherboard driver or USB thing. Ugh.
Unfortunately at the moment there's a different fire pulling me away for a little bit here.
I did get an "nicanerr.txt" dump, if it is useful:
