That's easy:

lsusb shows you the bus and device number.

ls -l /dev/bus/usb/002/
for all devices on bus 2 or

ls -l /dev/bus/usb/002/006
for a single device, the 6th e.g.

> usb 1-1.2: >new full-speed USB device number 5

I think that means that you have connected the device to bus 2 which is a 
USB 1.1 bus. The kernel has given the device the number 5. This is not always 
the same. If you disconnect and reconnect it will probably have the next 
number. No idea whether there is an overrun after 999 ;-)

So you should see the access rights with
ls -l /dev/bus/usb/002/005

You may configure udev so that a symlink is created (/dev/cryptostick-0 or the 
like) and that the device rights are set accordingly. But that is not GnuPG-
