USB device for ppc440epx

[Leonid]

Hi, Josh:

Ooops, I didn't notice I have hijacked someone's thread, I thought I
created a new one. 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.

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.

BTW, it's considered impolite to hijack a thread to ask a completely
unrelated question.
