USB 3.0 Kext Causes System Freeze - Mavericks 10.9.2

I have recently updated to 10.9.2 with no problems. I just purchased a Western digital Elements 1TB USB 3.0 portable external drive.

When plugged in to the USB 3.0 port it appears, and is accessible, but if I run a program (usually from the dock), it freezes the whole machine, and I have to reset. I booted from an identical build of Mountain Lion using the same DSDT file, same settings and the drive works perfectly yet there is no kext in ML extensions related to USB 3.0 that I can find. I removed the generic kext on the Mavericks build, and now the drive doesn't even show up, and no freeze. I can't figure out how the drive even works in ML without a kext. I'm stumped.

I am running a Gigabyte GA-H61MA-D3V Rev2.0 Bios F4 with a custom DSDT not created by me. I have tried using Chameleon and other software to extract my own working DSDT, so far unsuccessfully. The DSDT was made by someone else with an identical board, and is has worked flawlessly. I read somewhere here that the generic USB3 kext in MultiBeast was modified from a LaCie kext. Could it be that it fails with WD drives? Why then would it work in ML with the same hardware and no kext?

The drive works fine in USB 2.0 mode, and It's the only USB 3.0 device I have to test with so far. Hope someone can help me.

Also, The Mavericks build is booting from an SSD, and the ML is running off a standard HDD, if that makes any difference.

I have been having the same issue with a GA-Z87X-UD3. Most of the time it works fine, other times inserting a device will cause system wide lock requiring reset/reboot. Anyone else having this? Could it be a conflict with another Kext?

Same problem here.

Motherboard GA-B85M-D3H, after using a few minutes a Western Digital via USB 3.0, system gets locket totally, even mouse and keyword stop responding.

I'm using Mavericks 10.9.2.

Any idea?

Is everyone in this thread using Western Digital external HD's when the freeze happens? At least 2 of you are. Firmware upgrades from WD? I'm using the universal USB3 driver on my external WD drive (with the latest firmware update from WD) without issue. On both the onboard and front USB3 ports.

Yes, my HD was a WD Password.

I've never upgraded firmware from a USB drive. Is that possible?

I did. Did you even go to the WD support site to check?

Edit,

Sorry, that came across as kind of snippy, not my intention!

I have the same behavior and I have a WD passport. I just upgraded from 10.9.1 (which was very stable) and only used multibeast to update audio and TRIM.
When booting with "-s" the system doesn't freeze.

I'm going to backup my WD and update. I'll report if it fix the issue for me.

Updated the WD passport firmware and no freezes yet.

Edit: Still no freezes!

Good to hear of your apparent success in solving the problem!

Well, my conclusions were wrong. I recently got freezes, even with the external WD unattached.

Edit: I'll try to unattach all usb connected to usb 3 ports and only use a mouse and keyboard connected to usb2. I'll have to see if this solves the problem.
