Thanks MH,

Ja,  I think it is mostly probable due to the the USB host device driver for SL811 in Linux-Arm Branch.
The reason I posted it I think that there must be many people who works Bluez in ARM-based system, (at leaset next large number for developers to x86), So I am asking how they solved this problems and whether I made some dull mistakes for using bluez.
Since the bluez site anounces that it support Xscale machine, I believe someone can answer me.

I am still need your help, Help me.

this don't look like a BlueZ problem. This really looks like a problem 
with the USB host controller.
