I would suggest leaving off "as-primary", but that's probably not the  
cause of your problem. "as-primary" was required in JUNOS 7.4 and  
earlier if you were using a USB to CF adapter and you planned on using  
the resulting CF in the primary CF slot. It's essentially a no-op for  
7.5 and later. Either way, it's not required for a USB stick.

I would also leave of the "swap-size 0" and stick with the default  
partition sizes. Again, that's unlikely to be the cause of your actual  
problem.

Does "show chassis hardware detail" show the USB stick?

If not, I would simply suggest removing and re-inserting to see if  
it's recognized.

If it has anything like San Disk's U3 "smart technology" you may want  
to repartition/reformat in a PC in order to remove that. Even so,  
you'll still need to use the "partition" keyword to "request system  
snapshot".
