You want the 'ls' command. In any case, try
tail -f /var/log/syslog
and reconnect your USB. I saw my device name (sdb1 for me) show up in the log.
I also used FAT32 and it looks like that nukes the dists/stable -> dists/hardy simlink, so you may need to cp/mv the correct dist subdirectory to dists/stable.
