Hi!

I have a fairly stable vanilla install of 10.6 updated to 10.6.2 via System Update.

The only problem is, no USB devices mount with a single exception of USB keyboard. Replugging or trying other ports do not work. Devices don't even light up their LEDs. Console logs has this line on every boot:

USBF: (varying x.xxx numbers) AppleUSBEHCI (0xb7a7000, 0xba3b000, 0xba4000, 0xba0a000, 0xba2a000 and such numbers):: Start unable to initialize UIM
USBF: ditto::UIMInitialize - Error occured (0xe00002be *- this number stays the same)

I have tried automatic DSDT patching with DSDTGUI, but it didn't help. When I open dsdt.aml, there is no Device node, no HPET, no USB...


I'm on a HP XW4400, which has HP 068a mobo. Search doesn't show anything on any OSX86 forum. There is NO legacy option in my BIOS.

Anyone care to point me to right direction? Thanks!

BTW my DSDT.aml is here:
http://dl.dropbox.com/u/1273571/dsdt.aml

EDIT:I've also noticed FireWire goes on and off in the same fashion. Either both USB ports and FW works and is present in Profiler, or not. Weird, huh?

It seems removing AppleHPET.kext solved both problems, USB as well as FireWire works now. Are there any repercussions with removing this kext?

Well, it appears that your HPET device is grabbing IRQs and conflicting with your USB ports. I have been fighting with the same issue on a Dell D620 that I've been working on. The best solution that I've found thus far is to remove the IRQ entries from your HPET, RTC, TMR and PIC devices in your DSDT and apply the DSDT USB patch found here:

thanks,man,i try many ways ,but just ur way fix my problem!!!

Hello,

I am having the same trouble with an xw4400 and 10.5.8: USB not working reliably.

Disabling the useless built-in Ethernet chip helped a bit, removing AppleHPET.kext apparently solves it, great thanks for the tip, but I really would like to have it fixed good at the dsdt level.

However, as you pointed, the dsdt is rather unusual, and there is no Device node, no HPET, no USB, except a list of (more or less) arcane acronyms with a valuer following. So if you'd care to share your patched dsdt, my xw4400 will be VERY happy

Here is the initial dsdt:

So... thanks for your help!

I need you help Stoovie .. How did you get OSX on your xw4400 and get everything working ? .. I've got a xw4400 with a Core 2 Duo E6700 .. An XFX 9600 GT and 4 gigs of Ram ... Thanks in advance for the help ...

Thanks
