USB Development

USB Development

[michael cardenas]

I recently bought a 3 button unimouse to use in linux with my imac, but
when I tried it out, I discovered that it uses the 1.16 spec and the usb
patch in linuxppc4.1 only handles up to 1.0.

But, I am a programmer, and I'm very interested in helping develop
linux.

My question is, where can I get the kernel source to get started and
what compiler do I use? Is there a kernel build faq? I recently
purchased the 4.1 cd, but I already had 4.1 installed.

I'd be willing to install pre r5 if I need to to work on the usb source.

Any pointers here will be greatly appreciated.

thanks,

Well.  4.1 ships w/ BootX (and a recent kernel then, yes? 2.1.125?).  Goto
http://cvs.on.openprojects.net (I think that's it) and see howto checkout
the kernel source there.  It's the most current for ppc.

Not needed..  R5 is nice tho <g>.

There are a few "problem" right now.  The current USB dev is being done on
Linus' USB stack.  OHCI (what's in most non-intel chipset based computers)
doesn't work.  OHCI is the main controller.  There is some hope tho.
linux-usb@suse.com is the current list.
http://soap.suitenine.com/usb/ has the current USB-ohci work and links to
the other OHCI driver for Linus' stack (merging soon).

	Go to w3.one.net/~johnb for a lot of information on iMac linux. It
also has instructions for compiling a newer kernel with USB support, and
the UUSBD has been updated several times since the 2.2.1 kernel that you
are probably using. I think you can also find links to the development
homepage for the UUSBD project. Finally, there is a new USB driver project
for the kernel that will merge with the UUSBD code base in the future (at
least, I'm betting on it). I'm running the 2.2.6 kernel on the iMac right
now from the instructions on the iMac linux page.
	Good luck!
