[anotherpatient]

After changing to the new Mavericks multi beast, my usb3 pcie express card is working no more!
So i decided to switch back to 6.0.1 but that didn´t work!
That is not very good while i want to use the USB3 for shooting Films and to save fast my Memorycards.

Please can someone help me out?
Thanks and regards

Try installing your USB 3 kexts of choice with tools like KextWizard and don't forget to repair permissions and rebuild the cache

Thank you!
I use the standard USB3 Kext what comes within MB 6.0.1, i have not such as one for his own.
An over installation of this one is not working, like for audio not too.
Is it so that an kext can´t overwritten with an older one?
I have the same with audio, someday i try an other voodoo and know the old one is no more working and i get some strange special signs like question mark that is standing head!
Can you help me?
Thanks and regards

To reinstall a kext (this also applies to another version) you simply have to delete the old one and rebuild caches + repair permissions with KextWizard (for example) then install the new one and again don't forget to rebuild caches + repair permissions.
