If not for ppc440epx (Sequoia board), ppc440ep (Yosemite) code will also help (according to CPU user manual USB device interface is practically the same). If this is already present in Linux kernel tree (from what version?), where it is located?=20 Thanks, Leonid.

USB mass storage works on 440EP already. It'll be in 2.6.25 in arch/powerpc. I would suspect 440EPx works as well.

I am very sorry if I have done so, I'll be more careful. Regarding USB Mass Storage there are device drivers (Host side) of course. However I am asking regarding USB device implementation itself. Can you point me to source files where this implementation is present for 440ep/epx? Linux has several examples of devices (like Zero Gadget) and I have used it with ARM CPUs. But I am not sure it is working on 440epx also.
