Never mind; I found the problem.  I had forgotten that at SuperSpeed or 
faster, the device descriptor uses a logarithmic encoding for 
bMaxPacketSize0.

The patch below should fix things up.  Let me know how it goes.

Quick test for Gen 1 and 2 devices work fine now. Highspeed also works
as expected before. I didn't test Fullspeed with various MPS, but I
don't expect any problem looking at the change.

Thanks for the fix,

And thanks for testing it.  Is it okay to put your 
"Reported-and-tested-by:" tag on the submitted patch?
