USB card reader not detected in fdisk -l
 

I am having USB card reader.
I plugged in machine, it won't show in fdisk -l command.
When I am giving dmesg | tail in command prompt as superuser, it gives me output like:

Type: Direct-Access ANSI SCSI revision: 02
Attached scsi removable disk sdc at scsi9, channel 0, id 0, lun 0
USB Mass Storage device found at 10
usb 1-5: USB disconnect, address 10

please help me to detect my usb card reader

You might be omitting some lines or reading the wrong part of the dmesg output. Run "sudo tail -f /var/log/messages" before inserting the thumb drive or SD card. Then insert the drive and monitor the live kernel messages. An SD card reader may have an /dev/mmc# device node instead of a /dev/sd# node.

Try different USB drives. The one you tried might not have a file system on it. My desktop creates fixed nodes for it's media drives before a card is inserted. So I have a /dev/sde for one of the slots set up at boot time. After inserting a card, an sde1 node is created.
