No usb without -f on hp DV6 laptop

[veda95]

Hi,

I just update from ML to Mavericks, and every things is ok and working if i use the flag -f.
If i don't, my usb doesn't work at all, i saw in the console that there is a problem with appleusbehci.kext (unable to get filter interrupt event source and error occurred 0xe00002be.

I don't think that's a dsdt problem because everything was working normally on all the osx version since 10.6 to 10.8.3 (or .4 can't remember)

My laptop is hp dv6 with core i3 2330, i have a custom dsdt,ssdt,patched aicpm.kext, no nullcpu, last fake smc and last chimera.

At the beginning when i updated to mavericks, that was the same, i had to use -f, but without it i didn't can boot at all, because of the cache rebuild, a message said me that the time is passed so rebuild iocatalogue...after searching, i use my hack who rebuild my cache and make me boot without -f (but without usb).
So i deleted all cache i made with my hack , and i can still boot without -f, and we are here!

If you've got an idea, it's not a big deal to have to type -f, but i like my system to be clean!
(i'll try to rollback appleusbehci with the 10.8.3 for testing, i waiting the combo update to download to take this kext)

Thank you.

So, that the same with the 10.8.3 iousbfamilly.kext, so i replace with the mavericks kext and have no idea left.

I found something, in system description, with -f there is 2 usb concentrator who use appleusbehci, when i don't boot with -f there is just one usb concentrator, where is connected my built in webcam...I think i'm on the way!

Hello veda95,

I have the same problem as yours. I have to boot with -f flag for my Two left USB ports to work.
Were you able to solve this issue?
I think the problem is that some kexts are not cached as a result of invalid signature. However, I don't know how to figure out which one.

Thanks.

AFAIK, invalid signatures don't matter. Use DPCIManager to rebuild your cache. Check for errors that prevent cache from being built.
