>Btw, what is USB MSC mode?
USB can have different OS drivers. MTP which is a portable player specific driver that microsoft supplies
with Window Media Player 10 and 11, and “native” on Vista.
USB MSC is the standard USB mass storage driver (same that works with various thumb drives
and USB external drives.)
The Express will default to USB MSC when MTP is not available (or better put Windows will install
the MTP driver and it wins when the Express is installed unless you change the driver in
the windows hardware manager.
Wikipedia has some good introductions. Before MTP each portable device had its own driver.
Apple and Ipods use “Isync” over USB for example.
I was thinking back a few decades, about the rumor Sun Microsystems did not burn in test
their computers. Instead they let them fail in the field, and just ship new parts. I assume MP3
players don’t get a week of operation at elevated temperatures before final acceptance testing either
