    I am sorry to ask this here because it is not relevant to OS X on aa1, but it did related to aa1

    Here is what happen:
    I brought a Made in China MP4 player, it is recognized, plug and play in Windows XP, however, it is not recognized in Mac OS X 10.5.6(never recognized). I also tried to plug it into my AA1 linux version, with the original Linpus, it works! I found this in the "system profiler". It shows that the system did recognized the device, but just .... i don't know....

    USB High-Speed Bus:

    Host Controller Location: Built In USB
    Host Controller Driver: AppleUSBEHCI
    PCI Device ID: 0x27cc
    PCI Revision ID: 0x0002
    PCI Vendor ID: 0x8086
    Bus Number: 0xfd

    USB Device:

    Product ID: 0xa4a5
    Vendor ID: 0x07c4 (Datafab Systems Inc.)
    Version: ff.ff
    Serial Number: A
    Speed: Up to 480 Mb/sec
    Location ID: 0xfd300000
    Current Available (mA): 500

    OS X is not particularly friendly to non-Apple MP3 players ... especially those that use "plays for sure" or whatever Microsoft's latest name is for their proprietary MP3 player interface. If it works in Linpus, you might want to investigate XNJB: http://www.wentnet.com/projects/xnjb/. I was able to use that to get my Creative Labs MP3 player recognized under OS X.

    FWIW I have seen two different "MP4" players on the local market, made in China,
    neither of which could play any MP4. Both were recognised as generic mp3 players
    in Windows XP, one was not seen at all in OS-X (real Mac), the other was seen
    as a USB generic storage device.

    The firmware on these devices is almost certainly designed to interface with
    Windows Media Player. If it works in Linpus somebody has done some work for you.
    Next you need to get the source code, (if you can for Linpus) and see how
    much hard work is involved building it for OS-X...

    There are a number of open source mp3 player/managers which build on OS-X,
    somewhat fewer m4a/aac, then getting your random player to work is as much
    luck as skill. Welcome to Apple's world where we know it works because
    they tightly control hardware and software.
