Strange, I just tried it here and got a serial number as usual (OS X 
10.7.2 and also 10.6.8):

             STORE N GO:

To check if your device does have a serial number can you run the 
attached python script using Windows?
The above device reports:

USB Device Id is USB\VID_13FE&PID_3623\079A1111814F57E3 (VBscript)
