I first want to say great stuff here. By far the most centralized resource for getting my d630 up and running on SL.

I have read through every post so far and found solutions to all my problems. The one issue that seems outstanding is USB ports working. I have found that my USB ports seem to be somewhat randomly working.

Most of the time the two ports in the back work. Occasionally it will change and one in the back will work and only one on the side will work. It's a big deal because I use external keyboard and mouse as well as an external HD.

My main question here is: Which specific kext file is responsible for USB ports? I haven't seen solid documentation of this anywhere. I would love to know which kext file i should be trying different versions of to resolve this issue.

Thanks for any help.
