Because you set it as bootable? Guest had no clue what the thread was about, ignore that and read my thread before his. You may need to format the USB because it's new, manufacterer may not had done it:
fdisk /dev/sdc
mkfs -t vfat /dev/sdc

All new problems require investigation, and so if errors are problems, try to learn as much as you can and report back.

So do I need to set it as bootable? How do I do that to a device?

When I booted back into Knoppix, the name of the drive changed from sdc to sdb. Does that have anything to do with why it didn't show up?

fdisk /dev/sdc
mkfs -t vfat /dev/sdc


The only problem is that fdisk is an interactive program. I can't just type that command and hit enter. What should I do in fdisk? Should I delete the partition?

I deleted all partitions and made the filesystem, then mounted /dev/sdb on /mnt. The directory showing up in /media is sdb not sdb1, and I checked the mount.

knoppix@Microknoppix:~$ mount -l | grep --color=always sdb
/dev/sdb on /media/sdb type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0000,dmask=0000,allow_utime=0022,codepage=cp850,iocharset=iso8859-1,shortname=winnt,errors=remount-ro) [Debian Inst]
/dev/sdb on /mnt type vfat (rw,relatime,uid=1000,gid=1000,fmask=0000,dmask=0000,allow_utime=0022,codepage=cp850,iocharset=iso8859-1,shortname=winnt,errors=remount-ro) [Debian Inst]

It appears that there is now a FAT filesystem on the drive containing all the files, with no partitions. I will try rebooting now.

I tried rebooting. The USB drive still did not show up in the boot menu. I'm going to try booting off an empty drive and see what happens. This drive is obviously corrupted.
