Hi, 

I was fortunate enough to buy USB 3.0 pendrive, 
which actually works with FreeBSD just ripped from 
package! (normal _empty_ FAT filesystem, no
garbageware added, no need to format).

It actually bounces from 40MB/s limit when reading
from it.

Writing is about 18MB/s.

Device is supposed to be "467x" which should 
be about 70MB/s.

And USB 2.0 hard limit is 60MB/s.

Wouldn't be nice to squeeze few additional
MB/s?
