Re the USB driver, I found some additional info at the Ingenic's web-site.
The Ingenic's web page in the development section for JZ4740, has downloads for USB Boot tool, but it looks like you need to develop your own drivers ?

My "Conversion Free-3" TFT 16:9 screen" mp5 player with TV-out, has an Ingenic JZ4725 CPU chip, and an overview of the JZ47xx chip is shown here...

The firmware is Version 1.3.0.12
The toolbox has two options regarding the firmware:
Recover System and Updating.
Does anyone know how the "Recover System" option works for this Ingenic player? Does it have a copy of the compressed firmware on-board and makes a recover from that file, or do you need a backup copy of the firmware?
...thanks for any additional info
p.s. If anyone is interested, I can post a review of this player with some pics. For the cost of ~$40US, it is actually quite a nice player.
