Now in my house, this is my dmesg

dmesg | tail
[ 6549.064607] sd 4:0:0:0: [sdb] Write Protect is off
[ 6549.064612] sd 4:0:0:0: [sdb] Mode Sense: 23 00 00 00
[ 6549.064616] sd 4:0:0:0: [sdb] Assuming drive cache: write through
[ 6549.089712] sd 4:0:0:0: [sdb] 1003520 512-byte hardware sectors (514
MB)
[ 6549.096014] sd 4:0:0:0: [sdb] Write Protect is off
[ 6549.096014] sd 4:0:0:0: [sdb] Mode Sense: 23 00 00 00
[ 6549.096014] sd 4:0:0:0: [sdb] Assuming drive cache: write through

so i do:
e/germana# ls /dev/sdb 
/dev/sdb

and i can not see anything

but i use:
fdisk -l /dev/sdb

Disco /dev/sdb: 513 MB, 513802240 bytes
16 heads, 62 sectors/track, 1011 cylinders
Units = cilindros of 992 * 512 = 507904 bytes
Disk identifier: 0x00000000

and i can see this is my pen drive.... or not??

should i do something else?
