Yes - just run the command as root and it will continue running and printing events to the terminal until you interrupt it with Ctrl-C. Here's some sample output showing an add/remove cycle for a USB flash device (although this machine has an SD reader I don't have a card on me right now so a USB stick was the closest I could get): http://fpaste.org/UwHH > I will have to do that when I get home this evening.

Make sure the usb-storage module is loaded and check to see if a SCSI host exists for the storage device. To do this you need to look for an entry in /sys/class/scsi_host that corresponds to the USB bus address of the card reader. E.g. the key from the example above shows up like this: $ ls -l /sys/class/scsi_host/ | sed 's/.*\ host/host/' total 0 host0 -> ../../devices/pci0000:00/0000:00:1f.2/host0/scsi_host/host0 host1 -> ../../devices/pci0000:00/0000:00:1f.2/host1/scsi_host/host1 host2 -> ../../devices/pci0000:00/0000:00:1f.2/host2/scsi_host/host2 host3 -> ../../devices/pci0000:00/0000:00:1f.2/host3/scsi_host/host3 host4 -> ../../devices/pci0000:00/0000:00:1f.2/host4/scsi_host/host4 host5 -> ../../devices/pci0000:00/0000:00:1f.2/host5/scsi_host/host5 host9 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/host9/scsi_host/host9 That last one is the one we're interested in. $ ls -l /sys/class/scsi_host/host9 lrwxrwxrwx. 1 root root 0 May 29 17:07 /sys/class/scsi_host/host9 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/host9/scsi_host/host9 If you've no other USB storage on the system this is easy enough to spot. If you do then you'll need to look at the PCI addresses and USB addresses to figure it out. If in doubt look at the info option to udevadm - it can print out all the attributes it can find for a device and often there's something in there that will identify the thing.
