USB 3.0 HDD ILLEGAL REQUEST asc:20, 0 (Invalid command operation code)

[Janaka Withana]

Sorry,

Seems one of the author suggested a fix.

Any other workarounds you could suggest that would not require me to 
recompile? I am using nas4free embedded.

I am using FreeBSD 9.1 to p4 (Nas4Free 9.1.0.1.804) and get the following
repeated errors using a USB 3.0 hard drive via a USB 3.0 port
