[winstonace]

anyone tried this fix?
http://www.projectosx.com/forum/index.p ... topic=1138
very close to real imac 11,1 ssd
but I can't get it to compile...
I feel that the solution is out there in the hub section under the ehci devices

Re: Possible fix for usb

If you use iasl to compile your dsl, use old version
the new versions can't compile the PLD
(require Package instead of Buffer)

like in iMac

Already downloaded it and been studying.

My goal is also to have just the 2 EHCI ports like the iMac.

Check your irq's in ioregistry explorer. I had the same issue and by reserving FOUR IRQ's to hpet in dsdt and removing irq's for TIMR, RTC, etc....both of my EHCI controllers work with the native 10.6.3 kext. Before I assigned the irq's to hpet (2, 4, 8, 14 I think) hpet would grab the same irq as the second ehci controller.

Re: Possible fix for usb

Both EHCI devices work natively and you can attach as many devices as you want without sleep issues
but you can only "mount" USB 2.0 devices
USB 1.1 devices (like mouse and keyboards) doesn't show up (unless you attach them to a HUB)
If you have succeeded in doing these (have two EHCI which act as a hub for USB 1.1 devices) please attach your dsdt.

Re: Possible fix for usb

I think my config matches your's and yes I only have 2 ehci controllers (no uhci) and both 1.1 and 2.0 devices work flawless. I attach my aml, you can decompile (sorry I don't have dsl any longer).
