USB storage "dongles" and umass driver

[Tom Parquette]

Hi.
I was looking at the Sunday ads and I found a LEXAR JumpDrive at a price 
that I could swallow.
I looked at umass and it talks about supporting a couple of models of 
SanDisk "dongles" in flash mode.
I do not know too much about these.  If my terms are incorrect, please 
correct me.

The question I have is, are these devices generic enough that other 
manufacturer's devices will work with the umass driver?
Something like this would be nice for transporting a few things to and 
from work.  e.g. Installing Lotus Notes under wine on my FreeBSD machine 
and using one of these USB devices for carrying my Notes ID file and 
personal address book.

Comments/insights?
Thanks.
