Subject: Re: [linux-usb] linux on imac

I've been able to compile up and talk to my imac via keyboard...

The combination of stuff that worked was:

linux-pmac-2.1.127.tar.gz
+ uusbd-1207.tar.gz
+ uusbd-imac-981209.patch.gz

It appears that the multiple keyboard stuff is not needed...

FYI - I compiled the usb stuff into the kernel... no modules - seems
to work.

In trying to compile up 2.1.129 - the uusbd stuff has a problem with
the definition of s_node.  Apparently it thinks that s_node should
have a "lock" field.  For the life of me, I'm not seeing why the compiler
croaks - or rather I see why it shouldn't work - I don't understand why
it works for 2.1.127 and not for 2.1.129.

I tried the kbd patches - they do not cleanly apply to 2.1.129...
nor to 2.1.127. But the kbd patch does not seem to be required 
to get the kernel booting.

Given enough eyeballs all bugs seem shallow.
