What was the difference between the first test and the second?
It worked with my hub, and just realized I should probably of put that test under the analyzer as well. Need to find a 2.0 PCI card and compare my results with that as well.

The test that worked is test3. Test1 did a write-through of any hardware cache that may exist between the write command and hardware. Test2 was an attempt at overlapped asynchronous I/O with notification of each report finishing.
Test3 I forced a flush and wait after each HID report is sent.

It is only about 45k.
This appears to fix the problem on my Athlon64 4800+ with nforce4 chipset.

I just tested this new one (I'll call it testbench3).
Without a clean boot, all my outputs saw quickly seven times, then once a little slower, then it repeats the sequence.
I'll try doing a clean boot now...
With a clean boot, it performs the same sequence (all my outputs saw quickly seven times, the once a little slower), but not as fast as without a clean boot.
Again, I've only got nine outputs hooked up (4,5,6,7,8,9,30,31,32).

What you should see is a fade in from 0 intensity to full intensity and then a couple of sawtooths.

Now that I look at it again, it does start with a fade in (what I thought was a slow sawtooth), then six or seven sawtooths.

Sweet. This really excesses the PBA command that has been gaging hubs and Nvidia Cripsets.
