This is the latest version AFAIK. Ver. 1.0.8.

And yes multibeast uses it also.

But not everyone wants to download 30MB for just one driver of ?100Kb.

Ok. Thanx for the reply. If this is the same one then no point of me trying since the one in MB{censored} doesnt work for me in DP4. Works fine in lion. Strange, but oh well.

Hey John,

Thanx for the tip. I am good with hackintosh, but not as good as you guys. I did a fresh install of DP4 with PXHCD from MB{censored}. So correct me if I am wrong, I don't have to rollback right ? Just install IOUSBFamily.kext, and IOUSBMassStorageClass.kext right ? Also, a n00b question for you, what exactly do you mean my rollback ? Re-installation of PXHCD ?

Thank you for help.

btw I prepared USB key with myhack 3.1 and then installed MB{censored} with necessary kexts for normal boot.

What I meant by rollback was that those 2 kexts in DP4 needed to be "replaced" or "overwritten" in S/L/E by the ones in DP3. As for the PXHCD ikext, it can be installed any way you find convinent. In my case I do this when building my USB installer so it can R/W to my USB3 ports and when I actually use it to install MtnLion.

I have a USB 3.0 SATA harddrive Docking Station to store stuff like disk images.

When I use the Lacie kext with the DP3 kexts, My USB Drive appears but my Bose Companion USB speakers are not registered. When I use the Lacie kext without the DP3 kexts, the speakers work, but the USB drive doesn't. Can anyone help? Maybe those DP3 kexts are missing some files?

Thanks a lot JohnJCash for DP3 kexts, it works with Mountain Lion GM. Before that I try IOUSBFamily rollback in MB{censored}, it works too but Chimera or Chameleon r2003 keep ignore kernelcache.

Now my USB 3 in GA-X58A-UD3R can mount external USB 3 drive.

Thanks

Hi,Thanks for this as it revived my etron usb 3.0 ports. However like the fellow who posted about his Bose system, my USB audio devices are also disabled now. Can you please post the (i assume) DP# version of AppleUSBAudio.kext that will match these USB kexts? I imagine that will resolve the problem until new 10.8 compatible Lacie USB drivers come out.

be careful installing the DP3 kexts, after install, I couldn't even boot in safe mode or single user, when i booted to another drive to delete the kexts & -f boot it still wouldn't boot

Dell Inspiron 17R N7110:

I had USB3 working for a while (before this package) but at some point the ports stopped showing devices in System Info. The ports themselves were still giving power but no device would actually work.

Using "IOUSBFamily.kext" and "IOUSBMassStorageClass.kext" from DP3 (above) fixed my problems. I didn't have to remove "IOUSBAttachedSCSI.kext".

Thanks much for this fix.

I'm only able to get this to work if I don't use kernel cache (either run with -f, or don't add UserKernelCache=Yes).

In case of using cache, PXHDC seems to be initialized after some of the usb controllers, which causes usbs to fail initialization and sometimes also leads to kernel panics.

This is not a big deal for me, since I don't restart very often, so a little delay doesn't affect me much. However, if anyone has a solution, I'd love to hear it.

I have a hp Pavilion g6-2012sq (chipset Intel hm76 express), and tested on 10.8 retail.

Thanks for the kexts, they help me a lot.

Hello All!

I have a mid 2010 Mac Pro v5,1 OSX 10.6.8 and am having trouble trying to upgrade it by installing a USB 3.0 PCIx card. From reading this and many other forums, it seems like so many others have had great success with this.

Unfortunately, however, when I tried it doesn't seem to work. When I installed a similar card with the NEC D720200F1 chipset, hooked it up to the internal power, and after trying various PXHCD.kext files mine doesn't seem to want to recognize anything plugged into it, USB 3.0, 2.0, or otherwise. What really doesn't make sense is that the PCI card and USB 'superspeed' both show up perfectly in the system profiler. The only thing I can think of is that there is some other kext or some other file that is interfering with the proper functioning of this card. (I had a similar type of problem a while back with a LexarUSB.kext that was interfering with reading DVDs in my optical drive, but once removed it was golden....how someone figured that one out baffles me lol). It seems as there are a lot of ppl really up on there stuff about this on here, so if anyone has any suggestions out there, I would love to try them out.

Thanks in advance for all your help.

Cheers!
