Hmm...  Yeah, don't worry about the 3" cable that came with the 801e.
I just asked because I've seen 6 foot cables that had issues.

I suspect this is probably some issue with the USB host chipset.  The
error messages you provided suggest a problem sending commands to the
dib0700 USB bridge, so this does not appear to be related to the
s5h1411 or the xc5000.

I'll have to take a look at the code and see what I can figure out.
Do other high speed USB devices work with your host without any
problem (like USB hard drives, etc?)
