This is largely to be expected -- there's a umass device being found, it's
being mapped to a SCSI disk device, it has a lousy transfer rate because you
plugged it into a USB1 port, and it's 250MB (a weird size, maybe). I get very
similar output with either my USB1 key (64M) or my removeable HDD (12G
leftover piece of junk in a generic USB HDD enclosure).

That's odd. I don't particularly see why one device would show up as two SCSI
disks (though it's not impossible).

Typicaly missing quirk. There was a quirks table early on in 5.X's life which
I believe has been removed by now. The quirks documented weird behavior that
specific USB devices have. In fact, I have a 128M USB stick that -- once I
had put in the right quirks -- worked fairly well, but now crashes the system
hard on removal.
So it's not _just_ you, there's more USB devices out there that give trouble
-- at least on 5-STABLE still. Whether any of my rambling applies to
6-CURRENT, I don't know.
