I'm supposed to get 10 hours of mp3 playback on one charge, yet when I record
using the line-in function, I get only about 2.5 hours of recording time before
the battery is wound down. Is there any wall outlet charger that supplies the
power of USB 2.0 ports for these portable devices?

The mp3 unit instructions says not to plug it into a hub, but plug it directly
into the computer USB 2.0 ports.

Right now, the player is charging on my 98SE machine yet it isn't recognized as
a device in Device Manager or My Computer. Maybe after it finishes charging, it
will let me install the device drivers for 98SE from a floppy.
