Digitizing audio cassettes and extracting the contents of digital cartridges.

I think this is one of the side affects of using open software. If the 
Talking Book Player had used custom firmware, no one would be 
complaining about the code used in the firmware unless it resulted in 
bugs or a lack of features. I don't have a problem that the Talking Book 
Player is using an older Linux kernel, and I won't until I start 
noticing bugs or missing features.

As I understand, one of the issues has to do with our practice of suspending and resuming connections with USB cartridges, so that they don't draw power from the battery continuously. We really didn't want to mess up something that is working quite reliably for most patrons most of the time.
