Wistar Thomson A1 Mp4 Player
 

I purchased a Wistarmedia Thomson A1 MP4 player. It worked fine under Tiger on the Macintosh. Since upgrading to Leopard it shows up in the System profiler as well as under the USB prober applications. But it won't mount on the desktop. Does anyone know if the Rockchip 2608 based devices are fully Macintosh compatible. I have tested several other devices that use Rockchip, namely Onda, JXD, Luckystar, Longhorn, Digi-In and all work perfectly on the Macintosh even under Leopard. I have four of these units for testing and they all do not get recognized under Leopard. Any ideas??
