It's an Intel D850MV motherboard, which I guess dates from 2001. My
next project will be to use a newer kernel to see if that helps.

I purchased a new stick, which at least has an active LED when plugged
in. However, this was the result:
$ sudo dd if=/opt/tmp/test of=/dev/sdd
Password:
dd: writing `/dev/sdd': Input/output error
0+1 records in
0+0 records out
0 bytes transferred in 0.009271 seconds (0 bytes/sec)
However, I don't see why this would work, for /dev/sdd is not
connected to my stick. It's not like doing dd /dev/fd0. That is,
there's no dev interface that looks to the USB bus and specifically a
memory stick. The /dev/sdd could be any scsi device.
In the Sarge /dev directory, I have a /usb subdirectory of interfaces,
but I don't know that any is designed for a memory stick. For example,
there are: cpad0, ez*, hiddev*, lp*, mouse*, scanner*, usblcd. It
would be logical to find an interface for a usb memory stick here, but
none seem like it.
