USB umass device errors and successes

Hi,

I've been trying to obtain a USB key/dongle that plays well with FreeBSD,
and found it harder than I expected. In the washup, I thought that I should
pass on my experiences FYI. I am running RELENG_5 on a P4 (Dell/Intel
Mainboard), and following output is from this machine, however I
experienced similar results on 4.8 RELEASE and 5.3 RELEASE ie devices that
worked on one tended to work on all and vice versa. As this is the -stable
list, I'm confining my report to RELENG_5 testing.

So, without further ado, here are some devices and their log messages:
