Re: [OM] Image Storage on the Road

Why is it necessary to have a USB interface in order to recognize a 
hardware interrupt?  In fact, if it doesn't recognize a hardware 
interrupt you are at risk of problems if you change cards and write to 
the card since the computer will probably be using the cached directory 
of the first card inserted.

That leads to much ugliness which occurred in the early days of PCs with 
diskettes but has long since been solved.  Are you also required to 
rescan when cards have been changed?  I don't think so.  If a rescan is 
required I would consider the hardware and/or software to be defective.
