I don't think there's an easy way to tell, at any given point in time,
which USB device is which. About the best you can do is say that
devices are enumerated in the order they're plugged in, and know in what
order they're plugged in. Of course, for devices that were there at
boot, it isn't quite that simple..

The best way I know of to deal with devices like this is to watch the
system logs when you plug the device in. For example, my laptop has a
built-in memorystick reader, which is recognised as a USB device. On
bootup, I see the following in /var/log/messages:
...
Jul 30 23:16:28 fizgig kernel: usb.c: registered new driver usb-storage
Jul 30 23:16:28 fizgig kernel: scsi0 : SCSI emulation for USB Mass Storage devices
Jul 30 23:16:28 fizgig kernel: Vendor: Sony Model: MSC-U02 Rev: 1.00
...
And the reader is under /dev/sda...
