SOLVED ! Strange problem with USB ports in 4430s

Hello , I hope you can help me , I just installed Yosemite on my Probook 4430s following the tutorial I posted here , and iI used the Probook Installer and everything works fine , but I have a slightly odd problem . It since since I installed only 1 port wants to run USB of the 4 that I have , in the other 3 , when I connect a USB flash drive , for example , connects and disconnects , Yosemite recognized , but spend 3 seconds and says retired incorrectly, then re- recognized and well in an infinite loop , the same happens when I connect my Lumia . Note that this did not happen at Mavericks and Windows . Thank you for your help . :D

Try removing GenericUSBXHCI.kext. It seems to have some issues...

Just what I delete directly from the extensions folder, rebuilt the cache and only that ? Sorry for the inconvenience, but yesterday I removed another kext and I caused a kernel panic and had to reinstall Yosemite. :thumbdown:

Check that it is deleted from also /S/L/E (and rebuild cache). And you could also try it with GenericUSBXHCI.kext...

Yes, this file is not on the /S/L/E folder, in fact, it has never been there, I researched something... and I think the 6 series need that kext.. but I´ve never been and I not know where to download it...

ProBook Installer probably places it at EFI/Clover/kexts/Other. Isn't that where you found it?

Yes , in fact I 've found besides the "Other" another that says " 10.10 " , the two had the kext , so I deleted both kexts in and I rebuilt the cache , but still not working USB ports ... :(

Try installing the latest version: https://github.com/RehabMan/OS-X-Generic-USB3

It probably won't help, as it seems the kext has issues...

I've installed and did not work :(, how weird is that Yosemite could only be installed from this port , using other ports never started the installer , which did not happen when I installed Mavericks .... is a very strange bug .. :(


EDIT: And now I just try to use the webcam and I've noticed the same thing happens with the webcam for a moment says that there is no camera connected , then for 3 seconds gives an image , then off again , as with USB ....
