Yeah -- this sounds like your usb stick/thing has no filesystem or 
partitions... If you don't mind experimenting with it then you can create 
those.

If it's a music player the chances are it expects a FAT16 (msdos) file system. 
If it's a memory stick that you want to use only with Linux (and maybe Mac) 
then you can go with an ext3 file system.

*Beware* You can toast your usb device if you don't research it and work 
carefully. I have one stick that I killed that way ;)

Try these:
1. At the command line type [fdisk -l /dev/sdc]
Here's an example from my pc:
Disk /dev/hdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xbfbaecdd

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1               1       60801   488384001   83  Linux

This shows an ext3 (83) fs on my drive - one big partition.

2. You can create a partition by using fdisk (try man fdisk) -- I don't have 
time right now to explain further.

3. After that you create a fs by [mkfs.msdos] or [mkfs.ext3] on the sdc1 
device that will exists after fdisk does it's job.

IHTH, a bit rushed, sorry,
