When I install PQI SD 512Mb Card into cardreader and plug it (the reader) into 
USB, lamp on the reader blink once.
Then I try:

# dmesg
...

scsi14 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 15

Attached scsi removable disk sdb at scsi14, channel 0, id 0, lun 0

# fdisk /dev/sdb

Unable to open /dev/sdb

When I try it via card reader All-in-one, the lamp shine and:

# dmesg

Why it can't find sdb1 when I use SDcard via Pretec SD Cardreader???
