PCI daughter card with USB on a 405GP

Hi !!!

Thanks all for your response... I apologise profusely for the delay in
responding....

I did go through all of your responses and this is what I did ...

1.  lspci -vvx  : the following is the output.  I still am finding out how
to understand this..
00:00.0 Host bridge: IBM 405GP PLB to PCI Bridge (rev 01)

        Interrupt: pin A routed to IRQ 0

2. ==== arch/ppc/mm/cachemap.c
I found that this file does not exist at all in the montevista Hard hat
Linux ver 2.0.  So I downloaded ver 3.0 as a preview kit and I am checking
to see if it exists ... I suppose it does... I have made the changes
suggested. But have not able to bring it to a workable state.

3. I downloaded and built the tool chain for the 405GP. And am running into
problems trying to compile the linux 2.4.22 kernel. I am not sure of what I
must do to create the treeboot image... I think by default it does not do
it.. it creates only the vmlinux.gz

4.  Both ALi and OPTi are having OHCI support

 I am in the process of procuring a Adaptec card to see if it could make a
difference for me...

selfish to be lonely alone.

I also met this USB problem on LITE_DW board when using USB keyboard and
mouse.Has it solved or not?
