Check dmesg, when something happens that the kernel logs it goes
into dmesg and /var/log/messages on centos. Different distros and
other unixes have different log file names for this, but dmesg is
pretty much everywhere. It should say that the usb stick was
detected as a storage device and what partitions are on it. Then
you can mount the filesystem on the partition, or maybe there are
no partitions and the filesystem is just on the whole disk like a
floppy. Dmesg should say it was detected though, then you would
run something like mount /dev/sdb1 /mnt or maybe
mount -t vfat -o uid=yourusername /dev/sdb1 /mnt which would say
its a vfat filesystem and make everything owned by you instead of
