umass troubles again

[Andrea Venturoli]

Hello.

I've a 4GB USB memory which is formatted as a single FAT32 partition.

When I insert it, I get:

> root: Unknown USB device: vendor 0x1e3d product 0x2092 bus uhub5

(I'd expect da6s1, instead of da6a...)

Now... isn't that a tenfold error?

> # df -h
> Filesystem                                  Size    Used   Avail Capacity  Mounted on

The partition should be 4GB, not 400MB...

Any hint on this?

System is 8.1-RELEASE-p2/i386.
